- 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.House sparrows (Maya) were introduced to North America in 1852. Since that time thesparrows have evolved different characteristics in different locations. Sparrow populations inthe north are larger-bodied than sparrow populations in the south. This divergence inpopulations is probably at least partly a result of natural selection: larger-bodied birds canoften survive lower temperatures than smaller-bodied birds can. Colder weather in the northmay select for larger-bodied birds. What type of evolution based on natural selectionaccounts for this observation? Explain your answer.Which statement/s can best explain how evolutionary perspective help us understand senescence? (a) Evolutionary theory allows scientists to compare closely related species that differ inhow they invest in reproduction and in body maintenance, to test for effects on the agingprocess. (b) Understanding evolution can generate predictions about how individuals with certain suites of life-history characteristics might fare in the aging process when compared to other individuals without those characteristics. (c) Because aging is a natural process for all species, explaining its evolution through natural selection is insufficient. (d) Evolutionary studies provides insight into the historical development of adaptations, such as the number of offspring an individual has, that may contribute to life-history trade-offs, such as aging. A. Three of the 4 statements are correct. B. (a) and (d) C. (a) only D. (b) and (c)
- When artificial selection is practiced over many generations, it iscommon for the trait to reach a plateau in which further selectionhas little effect on the outcome of the trait. This phenomenon isillustrated as shown. Explain why it occurs.The elaborate tail of the peacock (Pavo cristatus) is approximately 120 cm to 150 cm long, while the tail ofthe peahen is quite short. The long tail reduces the male bird’s ability to maneuver and fly and makes him moreconspicuous to predators. Suggest at least one reason why this cumbersome structure has not been eliminatedby natural selection.Which scenario would be a moder nexample of Lamarckianismm? A strain of houseflies resistant to insecticides emrges Squirrels separated by a river are found to be unable to interbreed Snails are found to have thicker shells generations after the introduction of a predator A son is bornw ith a portion of his right index finger mssing -- the same portion that was severed from his father's hand in an accident.
- Competition is most intense between members of a(n)_______ . Predators and their prey act as agents of__________ on one another, resulting in a formof evolution called______ . This results in the evolution of characteristics called______ that help both predators and their prey survive andreproduce.Ancestry prediction in 23 & Me is continuously updated as new individuals aregenotyped. This can change an individual’s personal predicted ancestry by refining theregion of ancestral origins or potentially identifying a less common ancestry in the lineage.This can similarly happen with animals where new breeds are identified in an individual’sancestry as new breeds are genotyped. Explain how ancestry prediction is done and howthat prediction can change as more individuals are genotyped.Sexual selection occurs whena. one sex has a higher fitness than the otherb. a species exhibits sexual dimorphismc. there is a male dominance hierarchy and only the alpha male reproduces. d. There is monogamous mating.e. A trait is favored by one sex such that individuals of the opposite sex possessing that trait have an increased likelihood of reproducing.
- . The upper forelimbs of humans and bats have fairly similarskeletal structures, whereas the corresponding bones inwhales have very different shapes and proportions. However,genetic data suggest that all three kinds of organisms divergedfrom a common ancestor at about the same time. Which ofthe following is the most likely explanation for these data?(A) Forelimb evolution was adaptive in people and bats, butnot in whales.(B) Natural selection in an aquatic environment resulted insignificant changes to whale forelimb anatomy.(C) Genes mutate faster in whales than in humans or bats.(D) Whales are not properly classified as mammals.I look up cougars or any animal they all look the same? Like If i type on google as example of tiger i see multiple tigers of bengal tiger but when its two unrelated bengal tigers they look so munch alike. Why can't they look differently Like me and my firend both humans but we have different facials and different hair styles and different lookig body but aniamls like bengal tiger or two dogs in same breed look so mucnh alike even though they not related to be siblingsFrom a biological viewpoint, speculate as to why many traits seemto fit a normal distribution. Students with a strong background inmath and statistics may want to explain how a normal distributionis generated, and what it means. Can you think of biological examplesthat do not fit a normal distribution?
