- SCIENCE, TECHNOLOGY, AND SOCIETY Why is knowledge gained from sequencing the Arabidopsis genome important even though Arabidopsis has no commercial value?arrow_forwardEVOLUTION LINK Like stems in general, some vines are herbaceous and others are woody. Tropical rain forests have a greater diversity of vines than in any other environment on Earth, and most of these vines are woody. Develop a hypothesis to explain why natural selection has favored the evolution of more species of woody vines (as opposed to herbaceous vines) in tropical rain forests.arrow_forwardTest Your Understanding Know and Comprehend 9.

- What would happen to a plant that had a mutation preventing it from being ablr to perform phototropism? Compare it to a plant with a mutation that allows it to do phototropism more quickly than other plants. Explain in term of natural selection.arrow_forwardThe drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?arrow_forwardWhat would happen to a plant that had a mutation preventing it from being able to perform phototropism?
