Most bats eat insects or fruit. Vampire bats, however, suck blood from birds or mammals. Like some snakes, and unlike any other mammals, vampire bats have thermoreceptors that can detect body heat given off by prey. Is the heat-detecting ability of vampire bats and snakes a homologous trait or an analogous one? Explain your reasoning.

Voles that are born in the Spring have thin coats as adults, while voles that are born in the Fall have thick coats as adults. Most voles live only a few months; voles born in the Spring are alive during the warm summer season, while voles born in the Fall are alive during the cold winter season. The environment experienced by the mother during pregnancy determines coat thickness in the offspring. Now consider a situation in which the environment the vole mothers during pregnancy changes, such that voles born in the Fall now have thin coats. Assume in this case that the Winters are still cold. This scenario provides an example of which of the following hypotheses?   a.Environment mismatch hypothesis  b.Endocrine disruptor hypothesis c.Thrifty genotype hypothesis d.Plasticity first hypothesis
How did the presence of an adaptation change the frequency of a specific trait in hummingbirds?   Most humans enjoy candy, cake, and ice cream. As a result of evolutionary history, we have a wide variety of tastes. This is not true of all animals. Cats do not seek sweets. Over the course of their evolutionary history, the cat family tree lost a gene to detect sweet flavors. Most birds also lack this gene, with a few exceptions. Hummingbirds are sugar junkies.  Hummingbirds evolved from an insect-eating ancestor. The genes that detect the savory flavor of insects underwent changes, making hummingbirds more sensitive to sugars. These new sweet-sensing genes give hummingbirds a preference for high-calorie flower nectar. Hummingbirds actually reject certain flowers whose nectar is not sweet enough!
You are a wildlife biologist researching black rhinos. During your time in Africa, you have observed two particular traits that allow some black rhinos to be better adapted to their environment. The first trait is an extra-long prehensile lip that enables the rhino to have more efficient browsing capabilities than rhinos with the usual size prehensile lip. Second, some of the rhinos in the study have extra-large ears that allow them to hear a potential predator earlier than rhinos with normal size ears. If you could breed black rhinos that have both of these good traits (an extra-long prehensile lip (P) and bigger ears (E), it wouldincrease their chance for survival in the wild. You have chosen the following two rhinos to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Parent 1: Heterozygous dominant for prehensile lip trait. Heterozygous for the longer…
