Health And Human Science Class

  

A. Select one of the case studies posted in Blackboard to complete the following sections.  You will be using this case study in subsequent assignments.

(i) Problem/Situation Description:   Identify at one significant problem related to health and wellbeing in this case study. Write a brief paragraph which tells the reader what is the problem.  

Rationale as to Why this is a Problem: Write about how this problem connects to your definition of health and wellbeing (1 paragraph). Indicate what is missing or the gap that indicates the situation you have described is a problem that needs to be addressed.    

A. Alternative Perspectives:

Two different perspectives are described in the case study. Write one paragraph for each perspective in which you respond to the following questions: 

From whose point of view is thi

DNA

Imagine you were Avery Oswald and you just finished extracting transforming factor from bacteria.  Based on how DNA looks to the naked eye when floating in ethanol (not your knowledge of the molecular structure): Identify one incorrect conclusion Oswald could have made regarding the characteristics of DNA.  Identify one correct conclusion Oswald could have made regarding the characteristics of DNA. 

Responses

Write a response for each document.

Instructions: Your post should be a thoughtful response and should include outside reference material from the internet or primary literature.

HIV Question And Answer

1. In regards to substance use and HIV association, people usually only correlate that to injection drug users. What additional substance use linkages are there to HIV? If your room-mate shared with you that when they were out partying, they were "high," had way too much fun, and may not have protected themselves. How would you react? How might you advise them to get an HIV test or protect themselves in the future?

Discussion 3

Analyze and evaluate a Human Ecology Current Events article. The article must be published during the  term that the course is taken. Write an analysis and evaluation of the article, paying particular attention to the  scientific accuracy of the material and focusing on how any problems addressed in the article could have  been avoided in the first place or the lessons that can be learned and used to create a healthy future human  ecology. Be certain to provide a complete Web Address (and citation) for the article in your post. Your  Current Event Journal should be approximately 600 words in length.
