Question: 1 / 400

What changes in response to the change in the independent variable?

Control variable

Dependent variable

The other options are incorrect because they either do not directly answer the question or are not related to the concept of independent and dependent variables. A control variable remains constant throughout the experiment and is not affected by changes in the independent variable. C is the independent variable itself and is not a change that occurs in response to the independent variable. D is a term used to describe a variable that does not change throughout the experiment. Therefore, B is the best answer as it directly states that the dependent variable is the one that changes in response to changes in the independent variable.
