Question

"Carl puts tadpoles into two groups. Group 1 involves 100 tadpoles in a five gallon container of water, which is covered by glass (knowing that the glass will filter out the ultraviolet radiation). Group 2 will be set up exactly like Group 1, except instead of being covered with glass, it is covered with an acrylic plexiglass, which will not filter out the ultraviolet radiation. Carl then places the groups outside for a period of one month, and observes the results. Which group is the control group.

a. Group A
b. Group B

Answer 1

The control group in this experiment is Group A, which is covered with glass to filter out ultraviolet radiation.

Step-by-step explanation:

The control group in this experiment is Group A. In an experiment, the control group is the group that does not receive the experimental treatment. It is used as a baseline for comparison against the experimental group. In this case, Group A is covered with glass, which filters out ultraviolet radiation, while Group B is covered with acrylic plexiglass, which does not.
