Please answer the following questions after listening to the recent episode of the Diane Rehm show from National Public Radio on childhood vaccinations. What is the argument against childhood vaccinations? What are the benefits of childhood vaccinations?  Are they outweighed by the negatives? What type of research is being performed to ensure the safety of vaccines? Do you believe that single-dose vaccines are better than administering vaccines in cocktails?

Multiple sclerosis is a condition that affects the central nervous system. In this assignment, you will explore this condition in more detail using the scenario below. Scenario: A friend of yours discloses that he was recently diagnosed with multiple sclerosis. Being the caring friend you are, you wish to know more about the condition and how you can best support your friend. You decide to research this disease further. To complete this assignment, do the following:Research this disease using a minimum of 2 sources. You can use your textbook for one of the sources. Choose the remaining source(s) from the GALE Virtual Reference Library provided on the Structure and Function of the Human Body library guide page.In a minimum of 2 pages (not counting the references page), address the following: Explain how multiple sclerosis affects the nervous system. Describe the treatment options that are available for your friend. State whether it was possible for your friend to have prevented this condition. Include a references page at the end of your document, formatted using the APA guidelines, that lists your research sources.

1. Type Microorganism you have  2. Gram reaction (if any), shape, and arrangement 3. Virulence factors  4. How the organism evades the immune system 5. Disease your organism can cause 6. How your organism can spread to others 7. Ways to prevent infection 8. How your organism will be treated  9. What a nurse needs to know about your organism 10. Prepare APA format typed essay that documents YOUR understanding of the information and how it pertains to your assigned organism.  APA is 12 point font Times New Roman with one-inch margins. 11. Include at least 4 APA  style references from scholarly articles and resources.  For each reference, you will provide an in-text citation by providing a quote or paraphrasing the author’s information.

What are the differences between polar and non-polar amino acids and what is the role of polarity in amino acids? What are the two types of absorption involved in amino acid absorption? Provide a 3 paragraph response.

Microscopy Lab Report This report is to be answered while reading the document called “Microscopy Report Instructions” and viewing the videos in that document. There are helpful hints and directions for each question in that document as well, so read carefully! Reminder: if you use sources that are not the Instructions document, include their URL after your answer for the question. Question 1. Complete the following two tables Your answer: use only -> (Bright or dark) For light field microscope Color of the background circle Color of the cells Your answer: use only -> (Bright or dark) For dark field microscope Color of the background circle Color of the cells Question 2. Explain how to achieve darkfield microscopy. What is the benefit of using darkfield vs. brightfield? There is a hint in the instructions document. Question 3. Explain how to use the oil immersion lens. Start with placing the slide on the stage. Question 4. Describe the types of motility that you saw in the video indicated in the “Microscopy Report Instructions”. Did the type of field used to influence what you saw at all? Question 5. Why might it be advantageous for a bacterium to be able to swim? instructions below for each Microscopy Report Instructions In in this document, I will walk you step by step through what you need to do to fill out the microscopy report. Notice that this is an instruction guide and will not have all of the answers for the report completely laid out for you. Goals: • Introduce the concept of different kind of microscopes. • What is the difference between light (Brightfield) microscopy vs darkfield Microscopy? • Review your understanding of how to view a specimen under oil immersion. When life was simple and we were in class, this lab report would have been filled out while you viewed different wet mounts (samples of pond water) under a light compound microscope and then under a darkfield microscope. This exercise has been adapted for our Remote lab. Question 1- should be answered while or after watching this video https://youtu.be/B9gul0IGUdM All that Question 1 is asking is for you to compare and contrast the colours (bright or dark) of the cells to the background of each respective darkfield microscope and then light field microscope. Question 2. Understand that the only difference between a light microscope and a darkfield microscope is the addition/ change of 1 single microscope part. The name of the part is mentioned in the YouTube video from question 1 between time 0:20 – 0:35. The answer for the rest of the question can be found on the same video. Question 3. I DO NOT WANT A DIRECT QUOTATION from your lab manual or PowerPoint slides. Instead, make sure to paraphrase and say it in your own words. What I want is simply basic instructions. For example: first, do this, then do this, then do that. Your answer should be provided in numbered steps. If you want to double-check your understanding, here is a good video to watch (especially from 06:10). Question 4. Make sure to answer ALL that is being asked while watching THIS SPECIFIC VIDEO and the video from Question 1. Question 5. I want you to give me a good logical answer. Think your answer through and focus more on the “why” instead of the “what”. “So that they can move around” is NOT a good answer and will get you a 0.

Energy Balance. Choose a “popular” diet to research and review. You can include The South Beach Diet, Atkins Diet, etc. Thoroughly research this diet, using reputable sources including some that are not published by the creators of the diet you have chosen. Once you have researched the diet, answer the following: Describe the diet itself. For instance, what foods are included, are any foods prohibited, what is the macronutrient distribution, etc. What claims does the diet make? Are they sound? Why or why not? Use what you have learned in class up until this point to analyze the claims. Would you consider this a healthy diet overall? Why or why not? Consider possible drug interactions with components of the diet that are emphasized. Would this diet be appropriate for any certain populations (e g., athletes, elderly, etc.)? Would this diet be appropriate for all populations? Consider variables such as cost, cultural influences, and sustainability. Why or why not? When searching the topic of diets on the internet, you will come across more false information than accurate information, so be sure and assess your sources’ reputability prior to using them to support your post.
