Question: Which describes the variable that is changed to test the prediction?

A)dependent

B)experimental

C)control

D)independent

The variable that describes the changed to test the prediction is "independent."

Explanation:

The independent variable is the factor which gets changed or can be controlled to see its effect over the experiment. Only the independent variable responds to the changes. The independent variable will be shown on the x- axis. The age and time are two different independent variable. These two factors are independent of everything else. The variable which can be easily manipulated during the experiment is called as the independent variable.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
