Answer 1

Answer: The dependent variable is weight; the independent variable is exercise.

Step-by-step explanation:

The dependent variable refers to the variable which depends on the independent variables which are the other factors that are measured.

The dependent variable is expected to change due to the manipulation of the independent variables. Since the researcher is investigating the effects of exercise on weight, the dependent variable is weight while the independent variable is exercise.
