For an investigation, mr. rose planted two groups of plants (groups a and b). both groups received the same amounts of water and sunlight and were planted in the same type of soil. group b received fertilizer while group a did not. he recorded the average growth of each group for five days. mr. rose recorded several predictions about his investigation. which of his predictions was correct, based on the data shown? a) the plants in both groups a and b will have the same growth until the third day.
b) by the end of the fifth day, group b will be more than one cm taller than group a. eliminate c) for both groups a and b, the most growth will occur between the fourth and fifth days. d) for at least one of the days, group a plants will have more growth than group b plants.
