Prompt #2: Feedback mechanisms are used by organisms to maintain the steady-state
physiological conditions known as homeostasis. Explain how feedback mechanisms maintain
homeostasis for each of the following
Prompt #1: Discuss one example for the following contributions: the nonconstancy of
species, branching evolution, occurrence of gradual changes in species, and natural selection as
the mechanism of evolution
Prompt #3: describe the following reactions of plants to light, including underlying
mechanisms: phtototropism, photoperiodism in flowering plants and budding, and seed
