Answer:

Effect of independent variable is studied on the dependent variable or subject of the experiment.

Explanation:

The independent variables are very important in an experiment. Basically the affect of an independent variable is studied on the subject or dependent variable.

Thus, it can be said that independent variable will produce the effect on the dependent variable.

Here in this case the different types of disinfectants are the independent variable and their effect will be observed on the bacteria (subject or dependent variable)
