In the ant-treehopper study illustrated in the text, why did the scientists assign plants in the study plot to the ants-present versus ants-removed groups at random—instead of, for example, assigning all the plants on the west side of the plot to the ant-present group and all the plants on the east side to the ants-removed group?

In a lab, scientists grew several generations of offspring of a plant using the method shown. what conclusion can you make about the offspring? a. they formed from meiosis and mitosis. b. they have half the number of chromosomes as their parent. c. they have low genetic variability among them. d. they will be able to reproduce only after they grow flowers.
