Question

1. Tuberculosis and cholera are agents that are single celled organisms with no nucleus these are examples of: a. Viruses b. Prions c. Parasites d. Bacteria e. Fungi 2. A major problem with cohort studies is that: a. Subjects may not follow prescribed behavior throughout study period b. Both exposure and disease are known at baseline c. Control group may not be truly comparable. d. None of the above are the correct answer for the question 3. Measuring the new and existing cases of disease in a community is would be called: a. Incidence b. Attack Rates c. Mortality d. Prevalence 4. True or false: Nazi experimentation on humans and the Tuskegee syphilis study has led to reforms and policy that have helped to protect participants in experimental studies. 5. True or False: Information on the distribution, as it relates to person, place and time, of disease gives clues about the determinants of disease.

00:01 Here the first question is about tuberculosis and bacteria.

00:07 These are the agents that are single -celled organism with no nucleus.

00:13 And these are examples of what? among the given options, the right answer is option d, bacteria.

00:22 So bacteria do not have membrane bond nucleus.

00:27 They are unicellular organism and are called procreous.

00:32 So both tuberculosis and cholera are bacteria.

00:37 So the right answer is option d.

00:40 Discussing the second question, a major problem with cohort studies is that which of their given options? actually, the major problem if this study is, it is more time consuming and often more expensive than any other type of studies.

01:07 And this is not given in the given options.

01:11 So the correct answer for this question is option d about the cohort studies is none of the above are correct.

01:26 Because it is more time consuming and often more expensive studies.

01:32 And discussing the third question, measuring the new and existing cases of disease is in a community.

01:43 Would be called it is called as option d prevalence so prevalence is equal to number of case of disease in a specific population at a particular point of time so prevalence include all new cases plus the existing case so the right answer for this question is option d and the next question is as a true or false statement...
