- Why does sexual reproduction present a special problem for burrowing or sessile animals and parasites such as tapeworm? A) Lack of available food resources B) Late sexual maturity C) Difficulty encountering a member of the opposite sex D) Temperature of the environmentarrow_forwardWhich of the following statements best describes the advantage of sexual reproduction in organisms? It reduces genetic variation, which may be useful in the future. It prevents adaptation in a changing environment. It yields offspring with novel combinations of traits. It eliminates the possibility of harmful traits being passed on. tnf: Which of the following statements best describes the functions of villi and microvilli? Villi and microvilli form the inner layer of epithelial tissue in the small intestine and increase the absorption of nutrients from chyme. Villi and microvilli absorb food through the small intestine via smooth muscle contractions called peristalsis. Villi and microvilli increase the surface area of the small intestine, which increases the absorption of nutrients by diffusion. Villi and microvilli increase the surface area of the small intestine, which aids in the absorption of bile salts and vitamin B12.arrow_forwardHow might coevolution between a specialized parasite and a host be affected by the occurrence of other species of parasites?arrow_forward
- In the greater ani (Crotophaga major) (Riehl 2011) and the acorn woodpecker (Melanerpes formicivorus) (Koenig et al. 1995), a group of females shares the same nest. However, when some females begin to lay eggs in the communal nest, their eggs are often tossed from the nest by other group members. Use a cost–benefit approach to explain why females whose eggs are destroyed still remain with the group. Do you think the egg-tossing females are really cooperating with the others in their group?

A) allows animals to conserve resources and reproduce only during optimal conditions B) can produce diverse phenotypes that may enhance survival of a population in a changing environment C) yields more numerous offspring more rapidly than is possible with asexual reproduction D) enables males and females to remain isolated from each other while rapidly colonizing habitats E) guarantees that both parents will provide care for each offspringarrow_forward
- Which of the following is the most defensible stațement to make about the role of haplodiploidy in the evolution of sterile castes? sterile castes presumably would not have evolved in the hymenoptera in the absence of haplodiploidy. owing to the prevalence of multiple mating in social hymenoptera colonies, haplodiploidy has probably had a negligible effect on the evolution of sterile castes. haplodiploidy is the primary factor responsible for sterile castes in ants, wasps and termites. haplodiploidy was not an absolute requirement for the evolution of sterile castes in social insects.arrow_forwardWhy are female birds more likely to be drab while males have fancy colors or especially long feathers? A) Drab colors promote a female's survival. B) Males are under specific pressure to attract a mate. C) Females choose their mate.
