Answer 2

These things are referred to as control variables.

• These variables might impact the experiment and are kept constant by the scientist to ensure that it is proper and fair.

• Any fundamental change in the key variable in an extensive experiment would distort the specific findings by invalidating the association of dependent variables to the independent variables.
