Answer: Dependent
Step-by-step explanation:
In an experiment there are usually two main kinds of variables: Dependent and indepent.
The independent variable, as the name says, does not depend on ther variables to get a value.
The dependent variable on the other hand, does depend on other variables (like the indepent variable) to get a value.
Thus, the variable that responds to the changes of the indepent variable is the dependent variable.
