Astudent sets up an experiment with two groups of bacteria. one group is exposed to the normal amount of mercury found in the environment. the other group gets a larger dose. which term describes the normally treated group?

experimental group

control group

variable group

independent group

control group

Explanation:

The control group is the one which is used in an experimental set up as a benchmark for the comparison of the changes that occur in the experimental variable or dependent variable. It is the group which does not receive any experimental treatment. The use of a control group in an experiment increases the accuracy of the results of the experiment. It is the group which is treated normally without causing any change.
