Quizplus · Accepted Answer

The controls in the experiments would be the birds that did not receive the drug being tested. This allows for comparison between the group receiving the drug and the group not receiving it to determine its effectiveness. The rats given the drug and the birds given another drug that was not being tested are not relevant to the control group in this particular experiment.
