Please help!! 35) In the garter snakes studiod by Arnold, the feeding response to slugs was highly correlated with the feeding response to leeches (rG-0.89 in each population). Consider a population where the response to both types of prey is initially low, because both slugs and leeches are uncommon. Global warming causes an increase in rainfall with a subsequent increase in both species, while other types of prey become rarer. al slugs and leeches will comprise89% of the diet of this population will begin to each more leeches but the feeding preference will be constrained by the response to slugs ) snakes will begin to each more slugs but the feeding preference will be constrained by the response to leeches d) the population will become extinct because the feeding response to both prey species e) the population will become extinct because all snakes will eventually eat leeches 36) In the context of adaptation, the diverse beaks of the Galapagos finches represent an example of a) how b) how every trait is not an adaptation c) how all differences between traits are not adaptations d) how adaptation can constrain evolution e) all of the above 37) In northern elephant seals, the dominant males ("beachmasters") father the majority of all offspring. Subdominant males mate occasionally. These are likely to be: a) younger males b) older males c) males that resemble females d) males that are the sons of the dominant male e) males that are larger than the dominant male 38) Which of the following could not be used to estimate the heritability of a trait? a) the regression of average offspring on average parent b) the regression of sons on fathers c) the regression of sons on foster fathers d) the regression of daughters on mothers e) the response to selection 39) Which of the following is most likely to be an adaptation? a) spot pattern differences of reticulated and Masai giraffes b) red pigmentation of mammalian and avian blood c) size differences between left and right claws of fiddler crabs d) plumage differences among grouse chicks e) amount of repetitive DNA in the genome 40) In the large cactus finch, there are four distinct dry season foraging strategies. Each associated with a specific beak morphology. What is the best explanation for why the cactus finch has not differentiated into four subspecies? a) There is insufficient additive variance for beak morphology. b) There is insufficient selection on beak morphology. c) Selection is relaxed during the wet season d) Mating is random with respect to beak morphology e) All of the above 41) In Pfennig's study of Batesian mimicry in kingsnakes he used three replicas-plain brown, aposematic/non-mimetic and mimetic. What was the purpose of the aposematic replica? a) a control for warning coloration b) a control for bright coloration c) a control for novel coloration d) a control for mimetic pattern e) a control for handlingExplanation / Answer

ANSWER:- C) Size differences between left and right clawsof fiddler crab
