Astudent conducts an experiment to see how music affects plant growth. the student obtains four identical plants. each one is potted in the same type of soil and receives the same amount of sunlight and water each day. plant a listens to classical music for three hours each day. plant b listens to rock music for three hours each day. plant c listens to country music for three hours each day. plant d does not listen to any music at all.

8. in the experiment described in the scenario, which group represents the control group?

a. plant b b. plant a c. plant d d. plant c

The correct answer is Plant D.

The group that represents the control group is plant "D," the one that does not listen to any music at all. This is the plant that is not being tested and serves as the model that represents the control group. If you want to know what is the variable in this experiment, then it would be the type of music each plant is listening to.

temperatures get warmer — and heatwaves are more common. nothing says summer like warm weather. this rise in temperatures is caused by the tilt of the earth's axis. our planet doesn't sit perfectly straight as it spins — it has a slight lean of approximately 23.5 degrees with respect to the sun, called the axial tilt.
