Suppose you were studying several species of monkeys. In one, males never helped females raise offspring. In another, males provided just as much parental care as females except for actually carrying the fetus during pregnancy. How does the fundamental asymmetry of sex compare in the two species? How would you expect sexual dimorphism to compare between the two species?

A) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is small and sexual dimorphism should be lower than for species in which males always help raise offspring.

B) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is pronounced and sexual dimorphism should be lower than for species in which males always help raise offspring.

C) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is small and sexual dimorphism should be higher than for species in which males always help raise offspring.

D) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is pronounced and sexual dimorphism should be higher than for species in which males always help raise offspring.

How did the imagery of witches flying upon broomsticks originate? Historians have found evidence that some medieval European âdrug cultsâ included women who would prepare a potion by grinding up belladonna plants into an extract. Known as an anesthetic and muscle relaxant, this extract was applied using long sticks on the skin for rapid absorption into the bloodstream. The resulting symptoms included slowed breathing, dilated pupils, heavy eyelids, and a delirious sensation of flying.

QUESTION 39

Claytonia virginica is a woodland spring herb with flowers that vary from white to pale pink to bright pink. Slugs prefer to eat pink-flowering over white-flowering plants (due to chemical differences between the two), and plants experiencing severe herbivory are more likely to die. The bees that pollinate this plant also prefer pink to white flowers, so that Claytonia
with pink flowers have greater relative fruit set than Claytonia with white flowers. A researcher observes that the percentage of different flower colors remains stable in the study population from year to year. Given no other information, if the researcher removes all slugs from the study population, what do you expect to happen to the distribution of flower colors in the population over time? 22.2

		The percentage of pink flowers should increase over time.
		The percentage of white flowers should increase over time.
		The distribution of flower colors should not change.
		The distribution of flower colors should randomly fluctuate over time.
