Trevor Bishop · Answer 1

The correct answer is that it is held constant throughout the experiment.

Explanation:

A variable that is maintained constant all through the experiment is known as a control variable, and it is not the main concern in the outcome of the experiment. In an experiment, if there is any kind of change in a control variable it would lead to an error in the correlation of independent variable to the dependent variables, thus, affecting the results.

Devan Mays · Answer 2

is held constant throughout the experiment.

the control group is used as a foundation for your experiment so you know what changes what and how to manipulate the independent variable.
