Discussion 1 Assignment and Peer Response:

Should endangered species be protected? In 1973, the United States passed the Endangered Act (ESA) to identify and protect organisms which are at risk of becoming extinct. The ESA was passed with strong bipartisan support in Congress and had strong public support. While everyone likes the idea of saving endangered organisms, implementing the act has not been simple and opposition has grown over time. Before you respond to the discussion prompt, review the below articles for two different perspectives about the ESA.

Fecht, S. (2018, July 31). What Are the Biggest Threats to the Endangered Species Act?

undefined

O’Toole, R. (2019, August 20). Save the Endangered Species Act with Common Sense.

undefined

Your initial post should discuss two arguments that might be used to argue that the Endangered Species Act should be repealed. Your reply to two posts by other students should include arguments that the Endangered Species Act should enforced without exceptions to cost.

Signature Assignment: Pernicious Anemia Case Analysis

Teri goes to see her PCP after feeling depressed last couple of months as well as experiencing a seizure earlier this week. The physician orders a few tes ts, results are shown below:

• Low hematocrit
• Low levels of Vit B12
• Low Oxygen levels
• Presence of autoantibodies against the parietal cell
• Peripheral blood smear shows abnormal RBC (large pale RBCs)

After viewing the results, Teri is diagnosed with Pernicious Anemia; a condition in which autoantibodies destroys the parietal cells found within the stomach.

Address each of the following regarding Teri’s case:

1. Since the parietal cell is destroyed, which substance(s) is Teri lacking as a consequence?
2. What is the correlation between destruction of parietal cells and Vit B12 deficiency?
3. Due to her condition, Teri lacks Pepsin. Explain why.
4. If Teri were healthy, explain what her RBCs would look like?
5. What is hematocrit?
6. Low oxygen levels stimulate her body to create new RBCs by stimulating which process? Explain that process in depth.
7. What protein transports oxygen in our body and explain its structure?
8. What cell secretes antibodies and explain the various functions of antibodies.
9. What are the different types of antibodies and give two characteristics for each?
10. Explain the structure of an immunoglobulin.

Specifics:

• Support your opinions with evidence from your readings and research.
• You must reference a minimum of three (3) scholarly sources in your paper, which includes one non-Internet source.
• Use current APA Style to format your paper and to cite your sources.
• Your paper/total responses must be 3– to 4-pages in length not including the title page, abstract, and reference pages.

answer the question below

You have the NMR, IR, and mass spec information, and need to figure out the structure of the compound.Please attach a picture of the structures that you think your unknowns are with a clear and thorough analysis of why you think it is right (a paragraph is fine for the explanation) for each of them. Please put the number of your unknowns at the top of the document.

Since childhood, Linda has always enjoyed the outdoors. She tries to spend as much time outside in the summer as she can because she lives in the Pacific Northwest, where summers are short. Now, Linda is 62 years old and is taking her grandchildren to the same lake house where she spent long days boating, swimming, and playing sports as a child.

Linda has noticed an itchy skin lesion on the superior portion of her right ear within the past two weeks. She is beginning to worry because it doesn’t seem to be healing. She packed a large-brimmed hat for her lake trip to keep her face and ears out of the sun. She wants to make sure she is helping protect her grandchildren from any potential skin damage, too.

If Linda’s lesion is a sign of cancer, which types of skin cancer do you think it could be? What other information would you need to know to make a more educated diagnosis?

1. Linda’s son thinks a biopsy might be necessary and urges her to follow-up with a dermatologist. In your own words, briefly describe the process of a skin biopsy.

2. In your own words, what is the difference between a benign and a malignant tumor?

3. Linda had a grandfather who was diagnosed with melanoma. She is now wondering if she inherited a gene that has caused her to have melanoma, too. Could this be true? Why or why not?

4. How has Linda’s exposure to sun throughout her life contributed to her possible melanoma? (Hint: think about what happens to the DNA of skin cells.)

5. How can Linda help protect her grandchildren when they are spending time outdoors? Be specific, use your own words, and include at least 3 ideas.

Craig works in a factory and is often exposed to extremely corrosive chemicals. He always follows the proper safety precautions when necessary. One day, his coworker tripped on a staircase and Craig rushed to see if he was okay. As he tried to help his coworker stand up, Craig’s hands and arms began to tingle and burn intensely.

He looked around and realized that the box his coworker was carrying had been filled with a corrosive material and had spilled on his bare hands and arms. Craig immediately ran to the sink and began running water over his skin, while his coworkers called 911. He was rushed to the hospital. While riding in the ambulance, he was in excruciating pain. He observed large blisters forming over his right arm, while his left hand seemed to hurt less than the right, but appeared to be more damaged.

The blisters forming on Craig’s right arm indicate that his burns are at LEAST which type?

• Did Craig do the right thing by rushing to the sink to rinse his skin with running water? Why or why not?
• Craig noticed that his left hand appeared to be the most damaged portion of his skin, but it didn’t hurt as intensely as the less damaged skin. In your own words, explain how this is possible.
• Explain, in your own words, why a full-thickness skin graft may be a better choice for Craig’s wounds when compared to a split-thickness skin graft.
• Research new types of burn care/treatment. Briefly describe a new burn treatment technique that has been developed in the past 5 years. (Rasmussen’s Library and journal databases are a great place to start your research.)

Will be more I can give the 6 labs I have done but answer the question cite properly and in own words plagarism free Word, that is the preferred format.

Do your best…with quality work.

Problem 1

You have been hired to be the head of a COVID-19 task force for Suffolk County and answer to the governor, in writing, with recommendations for this area of Long Island.Begin your paper with an Abstract, which summarizes the (1) overall purpose of the study and the research problem, (2) the basic design of the study, (3) major findings or trends, and (4) recommendations. ** Sometimes it is easier to write this brief paragraph at the end when more information has been gathered! Next, include an Introduction, which explains about the details about the virus, it’s origin, timeframe and any other facts. Then, the Problem, which includes statistics of age groups effected, those not affected, mortality rates and changes in how we havedealt with the virus in the past year. Next, the Solutions and Treatments. This includes drugs, therapeutics, and vaccines; pros and cons of what was initially done and what is now recommended and any experimental treatments and how they work. Also, define a “vaccine” and why the one that has now been developed really is an “experimental gene therapy”! And lastly, Recommendations. From what you learned from your research and using the scientific method and experimental design, make logical recommendations.

I need guidance in understanding, and being able to complete the questions that will be given. it’s ten questions all calculations. please use the sheet down bellow for tables.
