Discuss 2.1: Physical Appearance No unread replies. No replies. Prompt On page 156, you will read about issues related to appearance-based discrimination. Using the Internet, find two other articles that discuss the issue of appearance-based discrimination. Be sure to review the articles, since you will need to support why you choose each. When you are finished, paste the links to the articles into the discussion board with a brief explanation of each link and why you thought it was worth including in the discussion. Check back in from time to time to read the links provided by your classmates and respond to the following: Do you think hiring/firing based on looks is an ethical issue? Is there ever a time where such an activity is justified?

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 test, 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: Since the parietal cell is destroyed, which substance(s) is Teri lacking as a consequence? What is the correlation between destruction of parietal cells and Vit B12 deficiency? Due to her condition, Teri lacks Pepsin. Explain why. If Teri were healthy, explain what her RBCs would look like? What is hematocrit? Low oxygen levels stimulate her body to create new RBCs by stimulating which process? Explain that process in depth. What protein transports oxygen in our body and explain its structure? What cell secretes antibodies and explain the various functions of antibodies. What are the different types of antibodies and give two characteristics for each? Explain the structure of an immunoglobulin.        Support your opinions with evidence from your readings and research.

In this reflective writing , I would like to agree or disagree & explain why ? And used examples in our day to day to respond to this reflective writing . You can cited a source if needed but it is not recommended Reflective writing about : I chose an article on studying dietary modifications to combat fatigue in Relapsing-Remitting Multiple Sclerosis (RRMS). The population being studied in the article is range from 18 to 70 years old, have clinically been identified as having RRMS by McDonald Criteria, are able to ambulate 25 feet with either no or unilateral support, living within 500 miles of Iowa City, and able to participate in dietary changes and shop for their food. These participants were further divided into two groups, the group values at 45 assuming a 25% attrition rate to continue with the 34 patients required in each group. To date the study has recruited 58 participants and is ongoing, with the group randomized blind to the study observer to a low fat or paleo diet. Changes in patient outcomes is measured by subjective report. As the expectation in the study is improvement in both groups, and the reported data is subjective, modifications to the study were added, with a 12 week observation of normal diet, and measure from and accelerometer for actual physical data was added. The study itself includes a 36 week, parallel, randomized trial with 2 groups broke into three 12 week intervals of observation, intervention, and follow up.

Provide an example of an invasive species found in the biome/ecosystem.  What are some of the negative impacts this invasive species has on the ecosystem?  What is being done to mitigate impacts? Provide one example of an endangered species found in the biome/ecosystem.  Briefly discuss the causes of the decline in the species and what is being done to help.    Please include at least 3 academic sources and make sure all sources are cited in your essay.  Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center.

Genetically Modified Organisms (GMOs) are a hot button of controversy throughout the world. Crop plants and animals with modified genomes are offered as ways of saving humanity from famine, but raise worries about creating monsters that may have unforeseen effects. Find and read/view internet materials about GMOs, and then write about the following questions: 1. What are the benefits and risks of GMOs? What regulations, if any, should apply to them? 2. Should there be limits on research on GMOs? Why or why not?

Briefly identify and discuss the categories of joints found in humans, and compare their overall structure and mobility features. Write your responses in a minimum of 250 words in APA format.

Question 1. For many years, the primary focus of osteoporosis prevention and management focused on calcium intake; and rightfully so, calcium is the chief mineral of bone mass development. However, in more recent years, our understanding of the role and importance of vitamin D on bone development and maintenance has increased substantially.Research and discuss the roles, interactions and physiological mechanisms of calcium and vitamin D on the growth, development and maintenance of bone mass through the lifecycle.Question2.  Colon cancer is a carcinoma that has some nutritional influences that may be more obvious than many other cancers. Proposed nutritional influence includes mechanisms involving fruit, vegetables, legumes, meat, dairy, whole grains and various beverages.Discussion this or another cancer and the specific nutritional mechanism of influence related to it.Question 3Antioxidants, such as vitamins E and C, may have considerable efficacy in reducing the deleterious effects of neuronal aging (neurodegeneration). Perhaps, even more interesting is the growing knowledge and understanding of the antioxidant/anti-inflammatory .potential of green tea, curcumin, ginger, berries and polyunsaturated fatty acids .esearch and discuss the potential role and mechanism by which these or other dietary substances may alter neuronal deficits associated with aging.Answer questions seperately and cite !Question 3.
