3The following experiment is used for the corresponding question(s).A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at twodistinct times of the year: early in spring when the oak trees are flowering and in midsummerwhen flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and looklike oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oaktwigs.How does the same population of moths produce such different-looking caterpillars on the sametrees? To answer this question, the biologist caught many female moths from the samepopulation and collected their eggs. He put at least one egg from each female into eight identicalcups. The eggs hatched, and at least two larvae from each female were maintained in one of thefour temperature and light conditions listed below.In each of the four environments, one of the caterpillars was fed oak flowers; the other, oakleaves. Thus, there were a total of eight treatment groups (4 environments × 2 diets).7) Refer to the accompanying figure. Which one of the following is NOT a plausible hypothesisto explain the differences in caterpillar appearance observed in this population?A) The longer day lengths of summer trigger the development of twiglike caterpillars.B) The cooler temperatures of spring trigger the development of flowerlike caterpillars.C) Differences in air pressure, due to differences in elevation, trigger the development ofdifferent types of caterpillars.D) Differences in diet trigger the development of different types of caterpillars.Answer: CBloom's Taxonomy: Applying/AnalyzingV&C Core Concept: SF, EV&C Core Comp: PSLO: 1.1Section: 1.3
