Explanation:

The dependent variable is the one that is measured and affected by other factors. Here, it is likely related to heart - function parameters like EDV, ESV, and cardiac cycle length as they are likely to change based on other factors. The independent variable is the one that is manipulated. The level of physical activity (resting or exercise) is something that can be changed to observe its effect on the dependent variable. Controlled variables are held constant to ensure that only the independent variable affects the dependent variable. Age, weight, height, health, and gender are factors that could influence the results and should be controlled.

Answer:

Dependent Variable: EDV, ESV, and cardiac cycle length
Independent Variable: level of physical activity (resting or exercise)
Controlled Variables: age, weight, height, health, gender
