Answer:
The "control" is used as a baseline or reference to determine if your scientific test had a response.
Step-by-step explanation:
In a scientific experiment, a control group is used as a standard of comparison to assess the effect of a treatment or manipulation. The control group is treated identically to the experimental group, except that it is not subjected to the treatment or manipulation being tested. By comparing the results of the experimental group to the control group, researchers can determine whether the treatment or manipulation had an effect.
