Poison ivy is a weed that produces an oil which causes skin rashes. Scientists want to perform an experiment to see if poison ivy grows taller when exposed to more carbon dioxide. How should the control group in this experiment be treated?

In these experiments the control group is compared with the comparison group.

The control group will sometime be in the presence of carbon dioxide, and will be controlled, where the analyst or researcher will take an expert position and then will compare it evolutionarily with the comparison group that the ideal would be that there is not ever a carbon dioxide

Explanation:

If we have two poison ivy research groups that are representative of the poison ivy that the researchers are looking to investigate the results will have much better credibility and will be more reliable.

On the other hand, the comparison of the two groups makes it possible to rigorously analyze whether or not poison ivy grows in the presence of this gas.
