Question

Which plants represent the control group?the experimental group?explain.

Answer 1

The control sample or the control group is a name given to a group of samples that are not treated with anything. They are left as it is. In this experiment, Dr. Lina Reyes wants to determine the effect of additional nitrogen to the fertilizer to the growth of the plants. Group B, which was given with fertilizer but without additional nitrogen is the control group. The Group A which was treated is the experimental group.

Answer 2

Group B is the control group

Step-by-step explanation:

A control group in the experiment is the one which is not treated/acted upon by independent variable in order to compare the changes occurring in the treated group.

Here Group A receives fertilizer with additional nitrogen while Group b gets regular fertilizer without any additional nitrogen.

hence, group b is the control group in this experiment
