Question

select the correct answer from each drop-down menu. in an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. he studies two set of people—those who exercise every day for an hour and those who dont exercise at all. in this case, the statement that people who exercise for an hour may have lower cholesterol levels is . to test this statement, the scientist would measure cholesterol levels in exercisers and non - exercisers. the cholesterol levels would be

Explanation:

1. For the first drop - down: A hypothesis is a proposed explanation or prediction that can be tested. The statement "people who exercise for an hour may have lower cholesterol levels" is a prediction that the scientist will test, so it is a hypothesis. A law is a well - established, universally accepted statement based on repeated experiments, and this is not a law. An observation is what is seen or measured, and this is a prediction, not an observation.
2. For the second part (the question about what the cholesterol levels would be, although the drop - down options for the second part are not fully visible, but based on the context of an experiment to test the hypothesis): In an experiment testing the effect of exercise (independent variable) on cholesterol levels, the cholesterol levels are the dependent variable, which is what is being measured (the data collected to test the hypothesis). But for the first drop - down, the correct option is "a hypothesis".

Answer:

First drop - down: a hypothesis
