In an experiment, a scientist hypothesizes that sunflowers that get 12 hours of sunlight will grow better than sunflowers that do not get any sunlight. They test the growth of sunflowers that get 12 hours of sunlight. After one week, they compare the results to sunflowers that do not get any sunlight. What is the control group?
