Question

A scientist wanted to design an experiment to

determine if ultraviolet light affects the
hatching time of eggs.
Which of the following should be used as a
control group in this experiment?
A. eggs that are from different animals
B . eggs that are exposed to ultraviolet
light
C. eggs that are not exposed to ultraviolet
light
D. eggs that have already hatched

Answer 1

The control group in this experiment should be eggs that are not exposed to ultraviolet light.

Step-by-step explanation:

The control group in this experiment should be eggs that are not exposed to ultraviolet light. The purpose of a control group is to provide a baseline for comparison. In this case, the control group will allow the scientist to observe the natural hatching time of eggs without the influence of ultraviolet light.

By comparing the hatching times of the control group to the experimental group (eggs exposed to ultraviolet light), the scientist can determine if ultraviolet light affects the hatching time of eggs.
