A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers, but caterpillars that hatch in summer feed on o ak leaves and look like oak twigs. How does the same population of moths produce such different -looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below. 7 Copyright © 2017 Pearson Education, Inc. Temperature Day Length Springlike Springlike Springlike Summerlike Summerlike springlike Summerlike summerlike In each of the four environments, one of the caterpillars was fed oak flowers, the other oak leaves. Thus, there were a total of eight treatment groups (4 environments × 2 diets). Which one of the following is not a plausible hypothesis that can be tested in this experiment? A) The longer day lengths of summer trigger the development of twig -like caterpillars. B) The cooler temperatures of spring trigger the development of flowerlike caterpillars.

You determine that tumor formation requires a large amount of the plant's energy for tissue formation. How might this change the number of offspring a plant produces, and what is the most likely explanation for this change? A) The number of offspring should increase because in general, illness increases the reproductive output of organisms. B) The number of offspring should increase because the bacteria will provide energy for the plant. C) The number of offspring should decrease because the plant will divert energy from reproduction to tumor formation. D) There should be no effect of infection on offspring production because energy for reproduction is independent of infection. Answer: C Bloom's Taxonomy: Application/Analysis Section: 1.3 33) Use the following information when answering the following question. In 1668, Francesco Redi performed a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat. What hypothesis was being tested in the initial experiment with open versus sealed jars? A) Spontaneous generation is more likely during the long days of summer. B) The type of meat used affects the likelihood of spontaneous generation. C) Maggots do not arise spontaneously, but from eggs laid by adult flies. D) Spontaneous generation can occur only if meat is exposed to air.
