Affects the dependent variable.
Step-by-step explanation:
A dependent variable is defined as the variable which is being tested during an experiment.
The dependent variable is the variable which is always dependent on the independent variable.
As in the experiments if the the value of independent variable then this change in independent variable will change the value of dependent variable.
For example: A scientist is recording the effect of light and dark on the moth by turning it off and on. In this case, the amount of light is independent variable and the moth's reaction is dependent variable. It means a change in the independent variable directly affect the dependent variable
