Trace the Scientific Method in a Primary Research Scientific Article

Written Assignment 1: Trace the Scientific Method in a Primary Research Scientific Article

Addresses the following course goals/objectives:

  • recognize and explain how the scientific method is used to solve problems
  • weigh evidence and make decisions based on strengths and limitations of scientific knowledge and the scientific method

Before attempting this assignment, you will want to revisit the Scientific Method Tutorial in the Science Learning Center under the Course Content area.  In addition, you will need to read and review the following article in your reserved reading area in the WebTycho classroom.

Yamauchi et al. (2010). Coffee and caffeine ameliorate hyperglycemia, fatty liver, and inflammatory adipocytokine expression in spontaneously diabetic KK-Ay mice. Journal of Agricultural and Food Chemistry58 (9), 5597-5603. May 12, PMID: 20405946, ISSN: 1520-5118.

Based on the paper above and using lab mice, researchers investigated whether or not coffee prevented the development of high blood sugar (hyperglycemia). The mice used in this experiment have a mutation that makes them become diabetic.(see http://www.sciencedaily.com/releases/2010/06/100609111316.htm)

A group of 11 mice was given water, and another group of 10  mice was supplied with diluted black coffee (coffee:water 1:1) as drinking fluids for five weeks. The composition of the diets and living conditions were similar for both groups of mice. Blood glucose was monitored weekly for all mice. After five weeks, there was no change in average body weight between groups. Results indicated that blood glucose concentrations increased significantly in the mice that drank water compared with those that were supplied with coffee. Finally, blood glucose concentration in the coffee group exhibited a 30 percent decrease compared with that in the water group.

(In the original paper*, the investigators acknowledged that the coffee for the experiment was supplied as a gift from a corporation.)

Answer the following questions by providing a clearly organized, explained, and written set of responses. Be sure to explain “why” observations occurred when requested.  Please clearly number your responses to match up with the numbered questions below.  A well developed paragraph will suffice for each question.

1. What was the hypothesis of this experiment? (Reminder: Hypothesis is a statement.) What question(s) was (were) the investigator asking?

2. Which group of mice represents the control group and which one represents the treatment group? Why?

3. Did the researchers follow the scientific method in their experimental design? Explain.

4. Do you think that there may be any possible biases or other problems in this experiment? Explain.

5. Based on the data, was the hypothesis supported, and what can you conclude from this experiment?

 

Written Assignment 2: Biology in the Real World (Position Paper)

Addresses the following course goals and objectives:

  • use knowledge of biological principles to ask relevant questions about the natural world
  • make observations and discriminate between scientific and pseudoscientific explanations

1. Select one of the following topics as the focus of your paper.

a) Genetically modified food. What is the purpose of human-made genetic recombinations in food? Are foods that contain genes resulting from artificial genetic recombinations really safe? What foods in your supermarket result from genetic recombination? What types of regulations exist for these foods? (For example, you might search the Food and Drug Administration website.) Clearly explain your reasoning for each answer.

 

 

2. Find articles related to the topic you selected. You can find assistance with searching for articles at the UMUC Library Subject Guides at http://libguides.umuc.edu/science.  These articles must be used to support your arguments, cited in the text where they are used, and included in a reference list at the end of your paper.

3. Write two pages, double spaced, excluding references. You must read the articles that you find and summarize the information they contain briefly in your own words. Extensive quotes from the article are discouraged. This assignment demonstrates the acceptable, ethical, and academic method for citing information from a public source. You may not use online encyclopedias as a source more than once.  Use APA style for citing references (seehttp://www.umuc.edu/library/guides/apa.html).

4. Post your assignment to your Assignments folder.

Human Growth and Development

Part 1:

Many people think that human development means childhood development from birth to adolescence. This assumption had been supported by the developmental theories of Freud and Piaget. However, we will learn throughout this course that development does not end at the start of adulthood; it continues till the end-of-life. This is the life span perspective of development. Describe the importance of the life span perspective of development.
Describe some of the main hallmarks of each one of these groups, using your own life experiences and observations explain why each one of these areas is important to study.

  • Childhood
  • Adolescence
  • Adulthood
  • Old Age

Justify your answers with appropriate reasoning and research from your text and course readings. Comment on the postings of at least two peers, and provide an analysis of each peer’s postings while also suggesting specific additions or clarifications for improving the discussion question response.

Part 2:

Several theories attempt to describe human development.

  • Briefly describe how Freud, Erickson, and Piaget developed their theories.
  • Explain why there is much criticism about race, ethnicity, gender, and social and economic status when it comes to human growth and development theories.
  • Choose two theories, each from a different area (e.g., psychoanalytic, cognitive, and behavioral or social cognitive theories). Briefly describe their main features, explain their major similarities and differences.

Written Assignment 2: Biology and Technology in the Real World
Background: This assignment will give you the opportunity to participate in ongoing scientific research. For the past several years, I have been involved in ecological research in old-growth forests in Wisconsin. In many areas the forest floor is dominated by a grasslike species, Pennsylvania sedge (Carex pensylvanica). The sedge may exclude other ground species by interspecific competition, which may decrease the number of species in an area, which is a main component of biodiversity. The Penn sedge “lawns” are probably caused by selective herbivory by an abundance of white-tailed deer. The deer do not like the sedge but consume most other ground plants. [Please read OLI Module 51 for information on interspecific competition & herbivory and Module 53 on biodiversity.]
Another problem in the forests is that dominant trees, such as white pine and sugar maple, do not show successful reproduction to replace the old pines and maples that die, which leads to the question – does Pennsylvania sedge decrease the establishment of tree seedlings? With support from a UMUC Faculty Research Grant to create this assignment, I collected data last summer that you can use to test three hypotheses-
Hypotheses
A. Pennsylvania sedge inhibits regeneration of white pine
B. Pennsylvania sedge inhibits regeneration of sugar maple
C. Pennsylvania sedge decreases biodiversity
Choice of Study Site – Practice with Google Earth: Most, if not all, students are familiar with the use of GPS (Global Positioning System) to navigate. I assume that many of you are also familiar with Google Earth, an interactive aerial map of the globe. It is a very useful tool. When we lived in Okinawa, we chose a home to rent before our 2011 move to Rhode Island by investigating the property and its environs on Google Earth, and are very happy with our choice. Google Earth can be downloaded free at earth.google.com
I also make use of Google Earth in choosing study sites for my research, especially when I was searching for remaining old-growth white pine forests in Upper Michigan. For practice with this relatively-new technology, I have included an exercise involving Google Earth with this assignment (under “Report” below).
Methods of Data Collection
Data were collected during 2-4 August 2013 in a study plot within a forest dominated by trees of sugar maple, red oak, and red maple at Trout Lake Cathedral Point, Vilas County, Wisconsin (Figure 1). All ground species were identified in 2- x 2-meter quadrats that were positioned as a strip of adjacent quadrats in transects of adjacent across the plot. In ecology, a quadrat is defined as a sample area and a transect is a sample line. Figures 2 and 3 illustrate the method of transects of continuous quadrats. Within each of the sample quadrats, the percent cover of Penn sedge was estimated and all established tree seedlings (defined as > 20 cm in height and < 1 cm in diameter at breast height) were counted. This site was chosen to test the hypotheses because patches of Penn sedge covered portions of the plots but was absent in other parts.
A total of 189 quadrats were sampled. Seedlings of white pine were most abundant, with a total of 124 plants in the quadrats, even though trees of white pine were rare. White pine, common in a stand adjacent to the study plot, has shown a recent burst of reproduction in the forest. There were 95 sugar maple seedlings in the quadrats. Other tree seedlings were few, so we will confine our analyses to white pine and sugar maple.
[Identification notes- Species on the forest floor can be identified from field guides, or more officially, from large books such Wisconsin Flora or the 3-volume Michigan Flora. Specimens, plants that typify a species, are also deposited in an herbarium, where plants can be submitted for identification. Nowadays, sites such as Wisflora from the Wisconsin State Herbarium (http://www.botany.wisc.edu/wisflora/) are available online. Another new trick that I use is to enter the scientific names of species into “Google Images” and compare it to digital photos of the plant. In the 189 Point quadrats, 20 herb species and 9 tree species as seedlings were identified. The most common herb was mayflower (Maianthemum canadense) in 89% of the quadrats. Three species, including eastern hemlock, were only in one quadrat. The hemlock seedling was quite a surprise as there are no hemlock trees in the vicinity.]
Figure 1. Trout Lake study area with patch of Pennsylvania sedge on the forest floor. Fig1.JPG
Figure 2. Transect line entering “lawn” of Pennsylvania sedge, with scattered white pine seedlings. Fig2.JPG
Figure 3. Quadrat of 2 x 2 meters created by centering two 2-meter sticks 2 meters apart on the transect tape. This quadrat on a sedge boundary contains small sugar maple and white pine seedlings. Fig3.JPG
Testing the Hypotheses – Data Analysis
The field data for you to use to test the hypotheses are given in an Excel spreadsheet with the file name “UMUCRiegeSedge.” UMUCRiegeSedge.xls Listed for each quadrat are the percent cover of Pennsylvania sedge, the number of white pine seedlings, the number of sugar maple seedlings, and the number of species.
So, you ask, where can I start to make sense of this big spreadsheet full of numbers? I would suggest one good way to begin is to tabulate the data by categories. For example, you might classify the quadrats by percent Penn sedge, such as 0-25%, 26-50%, 51-75%, 76-100%. Then you can average the number of seedlings or number of species per quadrat for each sedge category. [Hint- be sure to use average numbers per quadrat and not total numbers within each category, as the Penn sedge categories will have different numbers of quadrats.] If you look at scientific papers, you will see lots of tables and graphs, as these are excellent ways for the reader to understand the results. When graphing data, the independent variable (cause) is on the x-axis and dependent variable (effect) is on the y-axis. Our hypotheses have Penn sedge as the cause, hence percent sedge cover will be on the x-axis and the seedling/biodiversity data on the y-axis. In your report, use graphs and/or tables, as well as a written summary, to present your analytical results. [Although the data are presented in an Excel spreadsheet you are not required to use Excel for the report. You can copy the spreadsheet into another program or analyze it manually with a calculator if you wish.]
I caution that this exercise differs from those typically found in an introductory science course. It is not a canned lab that is designed to illustrate a process. In other words, the outcome may or may not support the hypotheses. The results may be “messy” and not as clear as designed labs. I urge you to be creative in your approach to testing the data. You need not be limited by my suggestions for categories or analysis. There is no one correct method of analysis. As this type of exercise is new to many of you, please do not hesitate to ask for advice as you proceed.
REPORT
Your report should be organized under the following bold headings (or a similar format).
Background – Choice of Study Site
I use GPS readings of latitude and longitude for reports on my study sites, so others may be able to locate them. The Trout Lake Point study plot for this Penn sedge project was approximately centered at 46o 02′ 45.00″ N latitude and 89o 40′ 07.25″ W longitude. It extended south to north about 43.0″ to 47.0″ and east to west about 6.0″ to 8.5″.
Please use Google Earth to locate the study plot (coordinates of latitude and longitude should be in the lower right corner of the Google Earth screen). The current aerial photograph on Google Earth was taken on May 9, 2013. Note the ice on Trout Lake, as it was a late spring. Note that the deciduous trees (maples, oaks, etc.) have yet to leaf, while the pines and other conifers are green. Look over the study site and its surroundings by navigating with the GPS coordinates given above and describe (1) the forest of the peninsula in general from what you can see from the aerial perspective and (2) why you think the study plot was not extended farther south or farther north.
Hypotheses
Simply restate the 3 hypotheses here.
[Normally a scientific report would next have a section on methods, but you can skip this since I already stated the methods in the assignment.]
Results
Here, report on your analysis of the data. Include tables and/or graphs and text to explain them. [Graphing reminder – best to put independent variable on x-axis and dependent variable on y-axis.]
Conclusions & Discussion
Summarize your analyses by concluding whether the data support or disprove Hypotheses A, B, and C. Then discuss how your conclusions might relate to the many factors that influence forest composition. For example, one factor not measured that may affect our data is the amount of shade. Although the study area had similar tree composition throughout, some areas contained thicker shade, which might decrease both sedge cover and species richness, thus obscuring any relationship between the two. Ecology is very complex, that’s why it is so much fun (but it makes it very difficult to verify causes and effects). Again, be creative in the discussion. Shade is just one example of many factors that influence plant growth.
One experiment leads to another in the scientific method. In your discussion, use your conclusions to generate at least one new hypothesis that could be tested to further add to our knowledge of the effects of Pennsylvania sedge.
GRADING
The written report on the assignment is due Sunday 18 July and worth 75 points (Google Earth description = 15 of the points). The report should follow the instructions given above. Full credit will be given for completing all parts of the assignment, for application of the scientific method, and for clarity of writing. There is no requirement for type of style or number of pages (remember, though, that “brevity is the soul of wit”)
Again, if you have any questions about the assignment, please feel free to ask me.

Case Study: Cell Biology and Genetics

Below are several case studies. Your instructor will either assign you a case study or have you select one. If all of the case studies have not been covered, your instructor may assign a case study that no one has covered. Be sure to integrate your knowledge of advanced physiology and pathophysiology across the lifespan with the clinical implications for the advanced practice nurse.
Case Study Posting Requirements

  1. Make sure all of the topics in the case study have been addressed.
  2. Cite at least three sources; journal articles, textbooks, or evidenced-based websites to support the content.
  3. All sources must be within five years.
  4. Do not use .com, Wikipedia, or up-to-date, etc., for your sources.
Case Study 1
Marsha and Clement are both carriers of sickle cell disease, a disease that is autosomal recessive. Their first child, Amelia, does not have the disease. Marsha and Clement are planning another pregnancy, but they are concerned about their second child having the condition. Clement’s dad died from complications of sickle cell disease shortly before Amelia was born.
1.    Draw a Punnett square to determine the likelihood of Marsha and Clement having a baby with sickle cell disease. What is the chance the baby will be a carrier of the disease, just like the parents?
2.    Marsha suggested to the nurse at the local family planning clinic that if the baby were a boy he might have a higher risk for developing the disease, just like his grandfather. If you were this Practitioner, how would you respond?
3.    When Amelia, who does not have sickle cell disease, grows up and marries someone who does have the disease, how likely is it that her children will have the disease?
Case Study 2
Maria is a sedentary, 68-year-old woman who is overweight. She complains that her hands and feet are always cold, and she tires quickly when cleaning the house. At her most recent visit to her doctor, her blood pressure was 184/98 mm Hg. She has edema around her ankles and legs, and her physician is concerned about an echocardiogram that indicates Maria has an enlarged heart.
1.    Identify two reasons why Maria will have tissue ischemia. How might this lead to hypoxia?
2.    What two early and reversible changes occur to tissue cells when they are hypoxic?
3.     What specific type of cellular adaptation has taken place in Maria’s enlarged heart? What made you come to this conclusion?
4.    Predict why Maria’s heart has become enlarged. Why doesn’t this enlargement give her the same cardiac strength and endurance as a well-trained athlete?
Case Study 3
Kevin worked for 10 years at a uranium mine, excavating uranium for a nearby nuclear power plant. Now, 25 years later, he has small cell lung cancer. Kevin is anorexic and has lost a considerable amount of weight. His muscles are wasting, and he is weak. He tries to move around the house throughout the day but tires easily. It has been difficult for him to access care, and the treatment for his cancer is just starting.
1.    With the ongoing exposure to the ionizing radiation, DNA damage occurred. Outline the three stages of carcinogenesis that occurred after his exposure to radiation.
2.    Kevin is normally a fit and active man, and his wife often commented on how much food he used to eat after a day at mine. Why would there be muscle wasting and weight loss now? Explain your answer using your
3.    knowledge of the metabolic changes seen with cancer.
4.     In some cancer patients, muscle weakness may result from the production of onconeural antigens. Describe the effects of these antigens. What form would this process likely take in Kevin’s situation?
Case Study 4
Felicity is a very busy 29-year-old woman in a professional career. She has diabetes mellitus, and is also pregnant for the first time. Due to her busy schedule, it took her three weeks to visit the family doctor to have the pregnancy confirmed. Felicity became very concerned when her physician asked whether she had been taking folic acid. It was all Felicity could do to remember to manage her insulin levels, and taking folic acid supplements was something she hadn’t even considered. Her doctor told her to take 600 μg of folic acid daily and advised Felicity to return later for maternal serum marker testing.
1.    Explain the potential teratogenic effect of folic acid deficiency on the developing fetus. What other risk factor is noteworthy in Felicity’s case?
2.    What is the benefit of maternal serum marker testing? What other test would be particularly useful to monitor the development of Felicity’s baby in this situation?
 
3.    When is the fetus most vulnerable to the effects of teratogens and why?

Immunity and the Common Cold

Humans have been plagued by disease throughout history and just about everyone has experienced the common cold at some point in time. During your life you will probably have more colds than any other type of illness. Humans have an amazing immune system that helps them fight foreign invaders, but sometimes the way your body fights these invaders causes unpleasant side effects that are often treated with over-the-counter medications.

You can learn more about the common cold at the following resource:

During the week address the following questions:

  1. What is the common cold?
  2. Should antibiotics be taken to treat a cold? Why, or why not?
  3. Why do humans not build immunity to the common cold?
  4. Would it be reasonable to expect that science will develop an immunization for the common cold in your lifetime? Why, or why not?
  5. You all have your own strategies for preventing or recovering from a cold. Please share your favorite strategy for fighting the common cold. Find and cite a source (reputable if possible) that either supports or disputes your favorite strategy.
  6. Later in the week, compare your cold fighting strategy to some described by your classmates.
    • Can you draw a relationship between the different strategies?
    • Do they have any commonalities?
    • How do they differ?

Neurology

Imagine that you are working in a neurology clinic. One of the neurologists tells you that as his or her practice is expanding, he or she is having difficulty meeting the education needs of his or her patients. Part of this problem is explaining the basic neuroanatomical structures to the patients in layperson’s language so that they understand their diagnoses and their underlying neurological impairments. The neurologist asks you to create a written guide for the patients, including both the CNS and the PNS. He or she describes what the basic neuroanatomical structures are, where they are located, how they interact, and what function they serve.He or she asks you to name the structures by using the correct technical language but to use layperson’s language as much as possible elsewhere.Your neuroanatomy guide should cover the following:Basic neuroanatomical structures (including the CNS and the PNS, as well as the structural packaging that protects the brain from the environment)
Locations of these structures
Functions they serve (what functions damage to these areas may affect)
How they interact. Be sure to explain the information in layperson’s language . Use APA format when citing material.

Application Global Health

Application Global Health Policy Paper The international human right to health has been established through various international agreements and other documents, as depicted in “Table 12: Sources
for the human right to health” (pp. 279–280). Among the principles that are asserted as human rights are the availability, accessibility, acceptability, and quality of public health and health care services. In this Application Assignment you are asked to
analyze a global public health problem using the international human right to health as a framework. In what ways would a human rights approach to the problem help to provide solutions to the health threat? Begin by examining a global health problem, such
as a particular infectious or chronic disease or type of injury. Alternatively, choose specific public health problems such as lack of access to medical or dental care, war, or a natural disaster. Research your topic by locating and reading at least three
primary research articles. Then, write a 3- to 5-page paper in which you address the following: Explain why your selected health threat is global and not national in nature. Using the international human right to health as a framework, describe the severity
of this problem. Focus particularly on the availability, accessibility, acceptability, and quality of public health and health-care services related to your chosen global health threat. (Refer to Box 17, p. 281.) Do you think that a human rights approach is
an appropriate and effective method for addressing this particular health issue? Take a stand and justify your position. Reading Course Text: Public Health Law: Power, Duty, Restraint Chapter 7, “Global Health Law” This chapter explores public health law on
a global scale. It identifies the major intergovernmental organizations working on global health issues. It also examines how decisions are made to determine international public health emergencies with the global spread of disease. Optional Resources The

Cellular Communication: Autocrine, Paracrine or Endocrine?

As you are learning, your body and the bodies of all organisms are highly complex, comprised of many different types of cells, each with a vital function that is required for the body’s survival. There are mechanisms that act like lines of communication, allowing different cells to communicate. Messenger molecules serve to coordinate signals between cells and between organs and are described as having autocrine (internal), paracrine (local) or endocrine (system-wide) functions.  Without these messenger molecules, how else does your liver know when to produce important proteins for homeostasis?  How does your heart know when to beat faster and then slow down?  How do your lungs know when to breathe faster?  The communications between your brain and organs, and between the different organs must be tightly regulated and controlled.

For this discussion board, select two types of messengers that our body uses to communicate between organs or between different cell types. 

  • Describe the messengers.
  • Discuss where the messengers are made and what is their function.
  • Are the messengers part of an autocrine, paracrine or endocrine pathway? 
  • What would happen if the messengers you have selected were inactive?

Stomach Cells

Your organs are wondrous things, each one with a different function vital to the homeostasis of your body. While it is easy for us to view a particular organ as a single item, it is in fact comprised of many different types of cells and structures, each one unique and yet each one working together to perform the functions of the organ.

In this Assignment, you will research an individual organ and its complexity.

The organ assigned to you for this essay is listed below:

Stomach

Your APA-formatted essay should include:

  • A description of the different cell types and any special structures. 
  • An extended discussion focusing on how these different cell types work together to provide the overall function of the organ. 
  • Include why each organ requires different cell types.
  • Why can’t the organs be comprised of just one cell type? 
  • What is the advantage of having different types of cells?

Your essay should include a cover page, an introduction, the body of the essay addressing the different topics and questions described above, and a summary paragraph. Please remember to reference any statement of fact and to include a reference list in APA at the end of the essay. The essay should be a minimum of 500 words in length not counting the cover page and reference list.

Immune System

The minimum length for this assignment is 1,200 words. Be sure to check your Turnitin report for your post and to make corrections before the deadline of 11:59 pm Mountain Time of the due date to avoid lack of originality problems in your work.

Review the major aspects of how the human immune system functions. How is the proper functioning of this system of major importance to all other systems in the body? What kinds of things can go wrong with the immune function and how do these problems interfere with human life?

Primary ciliary dyskinesia (PCD)

Discuss why this reversed arrangement may be a symptom of PCD and what else cna result from the malfunctioning of cilia in PCD

Primary ciliary dyskinesia (PCD) is a recessive genetic disorder that causes malfunction of cilia. Cilia are found on cells in almost every organ of the human body, and the malfunction of cilia is involved in several human disorders.  During embryological development, for example, cilia generate a leftward flow of fluid that initiates the life-right organization of the body organs. Some individuals with PCD (see Module 4.18 checkpoint question) exhibit situs inversus, in which internal organs such as the heart are on the wrong side of the body. Discuss why this reversed arrangement may be a symptom of PCD and what else cna result from the malfunctioning of cilia in PCD.

Homeostasis

The minimum length for this assignment is 1,500 words. Be sure to check your Turnitin report for your post and to make corrections before the deadline of 11:59 pm Mountain Time of the due date to avoid lack of originality problems in your work.

After she leaves, Shane continues to scream and cry until you are able to soothe him. Lisa often gets frustrated when trying to play with other children. She takes toys from their hands and even hits children with the toys. Next, address each of the following points according to the teaching approach/setting that best reflects your style in your desired classroom setting (e.g. Montessori, Reggio Emilia, Waldorf, traditional preschool, etc.): Outline a specific plan for addressing the discipline or guidance scenario. Explain how your plan would support the teaching approach/setting. Describe how you will create an effective partnership with parents to address the discipline or guidance scenario. Describe one or two possible obstacles you might encounter when implementing your plan. Discuss how you will address these obstacles. The paper should be three to four pages in addition to the title page and the reference page. Use at least two scholarly sources in addition to your text.

Ecosystems

Select a representative natural ecosystem in your area or one in which you are interested- such as a lake, preserve, or park- that is managed for native species.

The paper has to be 1,000 words explaining the following:

-The major structural and functional dynamics of your selected ecosystem

-How humans may have affected the cycling of matter in ecosystems, including effects to the nitrogen, phosphorus, or carbon cycle

-How knowledge about that ecosystem’s structure and function can help or has helped to develop plans for its restoration or management

-The implication of species interactions on your selected ecosystem.

Obesity Research Paper

You are the long-suffering aide to State Assemblywoman Smith, a well-meaning but excitable senior member of the California State Assembly. She has been too busy working on her re-election campaign to learn about a topic her constituents are concerned about- the rise in obesity rates. She needs to be educated on the topic of obesity. Because she knows that you are a CSUF student, and therefore highly scientifically literate, she has asked you to prepare a 1000-word (maximum) topic summary paper. Your state assemblywoman is extremely busy, has many other commitments, and is not a biologist. Therefore you need to be concise and clear, yet thorough.

In your paper, you will include the following (about a paragraph for each point):
1. How is obesity defined? What are the dangers of being overweight, even if not in the “obese” range? Support your answer with evidence and reasoning.
2. What factors strongly influence the probability of becoming obese?
3. The mayor of New York City, Michael Bloomberg, proposes a ban on the sale of large sugary drinks, while providing “Health Bucks” to use at farmers markets. Would you support a similar program in Orange County? Why or why not?
4. Propose a project or bill that the state assemblywoman could become involved in that would help decrease the obesity rates in our population (aside from the ideas proposed in New York City). Describe who you would target (i.e. people already suffering from the problem, kids, etc), and how. Remember, we are in a recession right now, so your plan must be cost effective.

Make sure to read the following articles:
“How to Fix the Obesity Crisis” by David H. Freedman, February 2011, Scientific American
“New York Plans to Ban Sale of Big Sizes of Sugary Drinks” by Michael Grynbaum, May 30, 2012, NY Times

You should also review relevant chapters in your textbook, and use other sources to fill in missing information. You must use and reference at least one additional source for this paper besides the Scientific American and NY Times articles listed above and your textbook (making the minimum references for your paper 4). Keep in mind that your paper should be well supported by evidence and having a good number of quality sources will help in this regard.

It is important that your paper be thoroughly researched and clearly written. You should define all your terms and be concise (1,000 words maximum). This assignment is designed to give you the experience of applying your knowledge of biology to a current controversy or topic of interest. You will use the same sort of method that you will later use as an informed citizen and consumer when making decisions that involve biology.

Other resources
Primary Sources: You will find information in the “primary literature,” which is where the research was originally published. You can find these articles by using CSUF’s on-line search engines, or by asking for the help of a CSUF librarian. Examples of the primary literature include Science, Nature, Proceedings of the National Academy, and Genetics.
Secondary Sources: You may also find relevant articles in recent newspapers, popular magazines, or popular science journals. These are referred to as “secondary” sources, since they describe research that was published elsewhere. Examples of these include The New York Times, The Los Angeles Times, The Guardian, Time, Scientific American, Discover, New Scientist, and Science News.
Websites: If you choose to use a website, be aware that most websites are not peer-reviewed, and often present inaccurate information. Examples of excellent websites include those of the National Academy of Science, the National Institute of Health, the Centers for Disease Control, and WebMD. If you are unsure of the appropriateness of a website, check with your instructor. Alternatively, the CSUF library has an excellent guide to evaluating websites at http://library.fullerton.edu/ under Guides for Undergraduates.

Transplant Criteria

Transplant Criteria

There are more people in need of an organ transplant than there are donor organs, and as such, there is a long waiting list of patients waiting to receive their transplant. Some of these patients will die before they receive the organ that could save their life. A waiting list is used to maintain the allocation of donor organs to patients.
For this module’s assignment, design your own 1-2 page organ transplant waiting list criteria. Some points to consider include the following: What are the factors that will establish a patient’s order on the list? How would you ensure that the most urgent cases receive proper attention? What happens if a patient exaggerates his or her condition in order to receive preferential treatment on the list?

peripheral vascular disease

Peripheral vascular disease (PVD) is a very common condition in the United States and is a leading cause of disability among people older than 50. It is more common in smokers, people with diabetes, hypertension and high cholesterol. Many people seem to think that this is a normal part of aging, and that nothing can be done or that the only alternative is surgery. Today, however, surgery is only one of several effective treatments available for peripheral vascular disease. Research and discuss the some of the debilitating issues associated with PVD and one non-surgical treatment that would be helpful for people with this condition. Be sure to give a reference for any outside sources you use

T-TEST FOR TWO SAMPLES

A drug company is measuring levels of oxygenation in patients after receiving a test medication. As the researcher, you are interested in whether Group I, which received the medication, has the same oxygenation levels as Group II, which did not.
1) Group 1: 2,3,3,4,4,7,8,9
2) Group 2: 1,2,2,3,4,4,5,5,6,8
 
Use Excel to run a t-test for two samples, assuming equal variances, with an alpha value of 0.05. Run the t-test and note:
1) Are you doing a one-tailed test or a two-tailed test (Excel will give you both)?
2) What is the probability that Group I is different from Group 2, using the p value? Is it significant against the benchmark of p < .05?
 
APA format is not required, but solid academic writing is expected.
 
This assignment uses a grading rubric. Instructors will be using the rubric to grade the assignment; therefore, students should review the rubric prior to beginning the assignment to become familiar with the assignment criteria and expectations for successful completion of the assignment.
 
THIS ASSIGNMENT NEEDS TO BE DONE ON EXCEL AND ALSO ANSWER THE QUESTIONS ON EXCEL SHEET AS WELL.

characteristics of our species and the role we play in our ecosystem

Unit 2 Assignment: Where do we fit in?
This week you are exploring the characteristics of our species and the role we play in our ecosystem. Have you ever considered the characteristics of your niche or thought about what might happen if you were forced to switch to another niche? This Assignment will give you the opportunity to compare and contrast the niche that you live in with an assigned niche (described below).
Your essay should include:

  • A description of your personal niche and of your assigned niche.
  • A description of both the similarities and differences between the two niches.
  • Consider what characteristics would provide a survival advantage to you or to the individuals who currently occupy that niche.
  • How have humans adapted to the two niches?
  • What difficulties might you have living in the assigned niche and why?
  • What types of cultural adaptations have evolved from living in your niche? Your assigned niche?
  • Your discussion should consider any biological adaptations as well; things such as dealing with food spoilage, insect vector control, food and waterborne illnesses, etc.

Your essay should include a cover page, an introduction, the body of the essay addressing the different topics and questions described above, and a summary paragraph. Please remember to reference any statement of fact and to include a reference list in APA at the end of the essay. The essay should be a minimum of 500 words in length not counting the cover page and reference list.

Selective Pressure and Survival of the Fittest

ur environment puts a great deal of pressure on every organism to adapt to its surroundings. Consider the differences between an animal that must survive in the arctic cold and one that lives in a hot, dry desert. Each one has adapted to their environment over evolutionary time in order to ensure survival. For example, camels have developed toes rather than hooves like horses, giving them an advantage while walking in desert landscapes. This is termed “survival of the fittest.” In this discussion board, you will focus on selective pressure and discuss examples of this type of evolution in our world.
Select two organisms (plant or animal) that represent unique adaptations to a particular environment.

  • Describe the specific adaptations and how they affect the organisms’ ability to:
  • survive in its habitat.
  • thrive in their particular niche.

What is your carbon footprint?

The problem:
Scientists have reported recently that the world is heating up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions of carbon dioxide (CO2)  and other greenhouse gases that are trapping heat in our atmosphere.But what can we do about it as individuals?
The average U.S. household produces about 150 pounds of CO2 a day by doing normal things like turning on the air-conditioning or driving the car.  This is about five times the world average!  So how much should we reduce our carbon emissions?  Some experts say that to prevent global disaster we need to reduce CO2 emissions by 80 percent.  Can we do that?
The experiment:
1.  Calculate your current personal carbon footprint by collecting data about your lifestyle. Print off the attached data sheet and fill in the information.
2.  Once you complete the attached data prep sheet go to the website:
http://footprint.stanford.edu/calculate.html
3.  Plug in your data and calculate your personal carbon footprint.
4.  Submit your results page to the drop box.
5.  After completing the calculations answer the questions on the following worksheet.

INTRODUCTION TO BIOLOGICAL SCIENCE

I need someone to help me deal with my biology assignments. It contains 32 quizzes and 3 exams. They are all online tests. I will provide enough documents which contain the answers to all the quiz and exam questions. The questions are all multiple choice and true or false question. As long as you finish them before the deadline, it is fine. I will also attch an two instruction which contains all the upcoming information you will need.
INTRODUCTION TO BIOLOGICAL SCIENCE
SYLLABUS
Course Objectives. This is an introductory biology course for non science majors, covering some most basic concepts in life science. As you explore the many facets of biology and its relevance to life in the modern world, you will see two unifying themes recurring throughout this on line course. Hierarchical organization – life is organized on many levels within individual organisms including atoms, cells, tissues, and organs. And in the larger world, organisms themselves are organized into many levels: populations, communities, and ecosystems within the biosphere. The power of evolution – Evolution, the change in genetic characteristics of individuals within populations over time, accounts for the diversity of organisms, but also explains the unity among them.
Textbook. “Biology concepts & connections” 5th edition or later edition by Neil A. Campbell, Jane B. Reece, Martha R. Taylor, and Eric J. Simon is adopted as the main textbook. ISBN: 0-8053-7160-5, paper -copy 0-853-7188-5.
The course consists of 12 units of instruction.
Dimensions of Evaluation.
Your final grade points include your grade points from 32 unit quizzes, three module exams. The 32 unit topic quizzes and three module exams (highlighted in red in the course syllabus on Blackboard) are posted to the Assessments folder. You should read the on line course documents, including various web links on a daily base, and take the quiz as you finish the reading of each unit, and take the module exam as you finish the module. There are all together three modules divided into 12 units. At the end of each study topic, there is a drop box assignment, you can e-mail your assignment directly to my e-mail address
The drop box assignment, the discussion thread activities, and other online assignments and study activities, i.e. web link activities, self check practice exams, electronic portfolio are self exam tools to see how much you have learned from each topic, and also serves as a feedback to me. The completion and satisfied answer of these assignments could help move you up to a letter grade. These assignments can also be submitted to me directly via e-mail.
50% of your final grade points will come from the total percentage of your 32 unit quiz grades; 50% of your final grade will come from the total percentage of your three module exams. Your final grade in letter from will be determined based on the following scale: 90 % or more = A 80% or more = B 70% or more = C 60% or more = D Lower than 60% = F
This grading scale will be applied only at the end of the course, and does not apply to individual exams. The instructor reserves the right to make fine adjustments on the grading scale at the end of the term.
Quiz and module exam
All quiz and module exam will consist of multiple choice questions and true/false, similar in format to the questions students encounter in each of the units of instruction.
Students may be tested on anything covered in the online course, audio lectures, required readings, external website information or discussion posts created by the professor.
Please Note: All required study work, all quizzes and module exams are expected to be completed by Friday, June 26, 2015, at 5:00 pm. All quizzes and exams will be submitted via the Blackboard for the instructor to grade.
Class Discussions and Activities
Each unit contains at least one discussion activity. These class discussions are important for developing a social learning community and a successful online course. They also reflect your class participation, so you are required to participate in the discussion thread.
Student discussions (on the Class Blackboard) are moderated by the instructor. Also, the instructor may pose questions for your thoughtful discussion and response. However, the primary purpose is for students to initiate questions and carry on discussions with each other. Your active participation not only demonstrates an understanding and appreciation of the subject matter (or lack thereof), it also contributes immensely to the overall learning experience (for all
students) in this course. Consequently, all students are expected to participate in a helpful and constructive manner in each unit’s discussion thread(s).
All postings are expected to be professional in tone, clear, competently produced and delivered; and their content should reflect an understanding of at least the lectures and assigned readings.
Failure to participate with requisite regularity and sagacity may result in a loss of points, up to one full letter grade, at the instructor’s sole discretion.
In addition to the discussion threads, each unit contains matching and fill-in-the-blank activities. Students are expected to do the required course work on a weekly basis. Preparation and participation (discussion threads and activities) can contribute materially to a good grade in this course.
It is strongly recommended that students complete TWO units per week. This will ensure uniform participation by students in the discussion threads and timely completion of all course requirements.

Format  consistent with APA guidelines. Use  Introduction, Level 1 Section Headings, Level 2 Section Headings, a conclusion and reference page. Your introduction should tell the reader what is to follow in the paper. Level 1 Headings give you the information. Each bullet point should have its own section heading. Your conclusion should summarize the contents of the paper. References (at least 3 academic quality) should be in correct APA format.

Genetic mutations and influence

in-text citation: This is a concept that eludes most people. If you are using an idea that is not common knowledge you need to provide a in-text citation (see style guide and assignment). When you are paraphrasing one of your sources, you need to cite. When you quote, you need to cite. When in doubt, cite. Not citing is called plagiarism. I will not deduct too heavily for the exact lack of citations, having a paper without any will have a negative effect on your grade.
Frequently asked questions about sources:
Once I have my academic sources can I use other non-academic ones? – Yes, you may. But do not lean to heavily on them for the content of your paper or your grade will suffer.
Can I use our book, or lecture? – Yes, but same as above, do not make them your primary sources.
Page length:
This is to be a 2 to 3 page paper. If you give me a short paper you will be marked off from anywhere from 20% to 90% of your overall grade. On the other hand, if you turn in too many pages (4+) you will also lose points. This will be a challenge for many of you. It may be difficult to write what you need to in so few pages, keep it pithy and to the point.
While this is not a English class and I do expect proper collegiate writing. Two hints: do not start your paper with a “Since the dawn of time” sentance. It is not a good way to start any paper. Also, set up what you are going to be writing about in the first paragraph. I don’t want to read a mystery research paper.
