A lab is preformed to study the effort of pH and heat on the function of the catalase enzyme found in carrot plants what is the dependant variable in this lab

A) pH. B) tempature. C) Enzymes activity. D) Water.

The dependent variable in this lab is C) Enzyme's activity.

Due to the changing of the pH and the temperature, the enzyme's activity is going to be changing. Therefore, since this is the value that is being measured, the enzyme activity is in fact the dependent variable.
