Answer:
A retrospective cohort study
Explanation:
A cohort study is an observational study in which individuals are classified (or selected) according to exposure status (exposed and unexposed) and followed to assess the incidence of the disease over a given period of time. Cohort studies can also be used to assess the risks and benefits of using a particular medication.
In the case of the research exposed in the question, one researcher analyzed the city's records to see who among the city's retirees had spent their careers working mostly indoors, without sun exposure; and outdoors with sun exposure. The sun is a major cause of hair cancer. Once participants were enrolled and screened, the scientist researched and examined the incidence of any form of skin cancer. This is a perfect example of a retrospective cohort study.
Answer:
A) A gymnast
Explanation: I have found the types of student that are in this middle school.
a. Tanner, a gymnast, is a fanatic about exercise and has lost a lot of weight during the six months since school started. Mr. Thomas rarely sees him at lunch.
b. Brit seems to be on an emotional roller coaster. Mr. Thomas has noticed that one day she may gorge on her lunch, a friend's lunch, and extra snacks, but other days she skips lunch.
c. Carson is painfully thin. In class photos, he appears to be the thinnest boy in his classroom every year. When Mr. Thomas visits the lunchroom, he sees Carson eating a regular school lunch everyday.
D. Shawna is about thirty pounds overweight and is always on a diet. She tells Mr. Thomas that she has tried one diet after another but nothing has worked for her.
- A gymnast is more likely to show signs of anorexia because the gymnast is obsessed with exercies and he lost a lot of weight during 6 months, which is a pretty long period and another factor is that Mr. Thomas rarely sees him when everybody is having lunch.
When a corporation purchases treasury stock, the acquisition <span>decreases the company’s total assets and total stockholders' equity.
These are mutually exclusive - even though they just bought the company, the assets and equity are still going to decrease, at least for the time being.
