A species оf beetle eаts the crоps оf fаrmers. Depending on their genotype, these beetles cаn have different levels of insecticide resistance, ranging from low resistance (easily killed by insecticide) to high resistance (often survive insecticide treatments). Farmers start spraying with insecticide in some area. Does this situation meet the requirements for natural selection? In your explanation, say which requirements it meets or does not meet (2-3 sentences, 3 pts. NOTE: Don't worry about distinguishing natural and artificial selection here.) Someone claims: "Insecticide makes beetles mutate in order to get resistance to it. When a beetle mutates to adapt, it passes that mutation down to its offspring." That claim is FALSE! Explain what is wrong with it, using the terms selection, mutation, random, and non-random correctly in your answer. (3 pts)
