Question
Female spotted sandpipers aggressively court males, and after mating, leave the clutch of young for the male to incubate. This sequence may be repeated several times with different males no available males remain forcing the female to incubate her last clutch. Which of the following terms best describes this behavior. poly gunny polyandry monogamy A region of the Canary forebrain shrinks during the nonbreeding season and enlarges when breeding season begins. This change is probably associated with the annual addition of new syllables to a Canary's song r sensitive period in which Canary parents imprint on new offspring crystallization of sub song into adult songs elimination of the memorized template for songs sung the previous year Although many chimpanzees live in environments containing oil palm nuts, members of only s few populations use stones to crack open the nuts. The most likely explanation is that the behavioral difference is caused by genetic differences between population members of different populations have different nutritional requirements. the cultural tradition of using stones to crack nuts has arisen in only some populations. members of different population differ in learning ability Which of the following is required for a behavioral trait to evolve by natural selection? The behavior varies among individuals. An individual's reproductive success depends in part on how the behavior is performed Some component of the behavior is genetically inherited None of these All of these Fruit fly courtship involves a fixed set of behaviors that follow one another in a rigid order. The behaviors include orienting, dancing and singing orienting, tapping and hugging orienting, clutching and singing orienting, tapping and singing The ability to correlate one environmental feature with another is called imprinting spatial learning cognitive mapping social learning associative learning ? How are mating systems associated with sexual dimorphism? In polygamous species the male is often highly ornamented In polyandrous species the female is more ornamented than the males In monogamous species the sexes are usually equally ornamented. In polygamous species the sexes are usually equally ornamented. Why did J.B.S Haldane state that he would lay down his life for two brothers or eight for cousins? He wasn't particularly fond of his cousins. He didn't understand the concept of inclusive fitness. If he were to make such a sacrifice, his genetic contribution to the next generation would be roughly the same as he had lived He knew these relatives would care for his own offspring. Why is the human brain not perfectly adapted to making modem-day decisions? Because components of the human nervous system evolved very early in our evolutionary history Because complex adaptations developed from previously existing structures, pathways and other traits. Because genetically based decision-making strategies that boosted our ancestor's chances of survival and reproduction were favored by natural selection over those that lowered fitness. Because rapid recent advances in technology have altered our environments within just a few dozen generation creating mismatches between our evolved decision-making strategies and the circumstances we now encounter All of these.Explanation / Answer
51. Female spotted sandpipers aggressively court males and, after mating, leave the clutch of young for the male to incubate. This sequence may be repeated several times with different males until no available males remain, forcing the female to incubate her last clutch. The terms best describes this behavior is (B) polyandry.
52. A region of the canary forebrain shrinks during the nonbreeding season and enlarges when breeding season begins. This change is probably associated with the annual (A) addition of new syllables to a canary's song repertoire.
53. Although many chimpanzee populations live in environments containing oil palm nuts, members of only a few populations use stones to crack open the nuts. The most likely explanation for this behavioral difference between populations is that (C) the cultural tradition of using stones to crack nuts has arisen in only some populations.
54. Which of the following is required for a behavioral trait to evolve by natural selection?
E) All of these. (A) The behavior varies among individuals; B) An individual's reproductive success depends in part on how the behavior is performed; C) Some component of the behavior is genetically inherited)
55. Fruitfly courtship involves:
(D) orienting, tapping, and singing
-Orienting: seeing and turning toward the female (secrete pheromones to attract male).
-Tapping: male comes up to female and touches her with her foreleg (tactile)
-Singing: male sings a song.
56. The ability to correlate one environmental future with another is called B. spatial learning
57. How are mating systems associated with sexual dimorphism?
B. In the polyandrous species the female is more ornamented than the males.
58. B. He didn't understand the concept of inclusive fitness (An individual's reproductive success and the effects of an individual's behavior on the reproductive success of kin)
59. E. All of these.
