Your friend remarks, “The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks.” Which statement is the BEST response to correct your friend’s misconception?

B.
characteristics acquired during an organism’s life are generally not passed on through genes to its offspring
C.
only favorable adaptations have survival value and unfavorable adaptations are removed from the population
D.
disuse of an organ may lead to its eventual disappearance

Short maturation time
B.
Producing offspring at many different times over the course of life
C.
Producing a lot of eggs at one time
D.

A subpopulation of a species of birds migrates to a different location from the rest of the species for breeding purposes. How might the genes change in the subpopulation?
A.
Their genes would change randomly and eventually revert to normalcy, which would allow the subpopulation to return to the main population.
B.
Their genes would change to better allow them to survive and reproduce in their new location.
C.
Their genes would not change at all and they would merely be a subpopulation living in a different location.
D.
Their genes would change so that they would continue to be well-adapted to their former location.

- Under a simple model, the evolution of asexual reproduction strategies will take over a population. The model relies on two assumptions. Which of the following are the assumptions? a. Reproductive mode does not affect how many offspring are produced by a female. b. Reproductive mode does not affect the sexual selection on males c. Reproductive mode does not affect the probability of offspring survival d. Both a. and b. e. Both a. and c.arrow_forwardIn Animal Dispersion in Relation to Social Behaviour, V.C. Wynne-Edwards suggested that animals act cooperatively and restrain their reproduction to a level sustainable by the environment. George C Williams argued that this was unlikely because ... A. animals are not able to gauge what level is sustainable B. there is little variation among individuals in reproductive output C. natural selection will favour individuals that reproduce above the sustainable level D. resource depletion is unlikely in naturearrow_forwardWhat factors influence gene flow between populations?A. The home range size of the species.B. Differences in animal behavior and life history strategies can form effective barriers to gene flow.C. Barriers to gene flow between populations are always physical geographic barriers.D. Reproductive barriers must involved anatomical differences that prevent mating.arrow_forward
- Which of the following is an example of a question about mechanism (not function)? A. What stimuli triggers a mother bird to feed her nestling? B. How does parental care benefit the mother's inclusive fitness? C. Why do some species have parental care but not others? D. Do mother birds get better at caring for their offspring over time?arrow_forwardThe best argument for how an unprotected species can evolve to mimic a second protected species (distasteful or noxious) and thus obtain protection is by A. Random changes in the appearance of the unprotected species that lead to increased fitness due to greater similarity with the protected species B. Individuals deciding that they need protection and mutating to look like the protected species C. Individuals changing their diet to increase pigment production to look like the protected species D. Natural selection for more advanced traits that are better to the inferior traits of organisms that do not look like the protected species E. Behavioral modification of the unprotected species to act like the protected speciesarrow_forwardSuppose two species of morning glories are reproductively isolated because in one species the flowers bloom in early April and in the other species they flower in mid-May. This would be an example of _______ isolation, which is a form of _______ isolation. a. habitat; prezygotic b. temporal; prezygotic c. temporal; postzygotic d. behavioral; postzygotic e. habitat; postzygoticarrow_forward
- In Darwin’s finches, a. occurrence of wet and dry years preserves genetic variation for beak size. b. increasing beak size over time proves that beak size is inherited. c. large beak size is always favored. d. All of the choices are correct.arrow_forwardIndividuals in a population of sunflowers have a range of flower sizes, and the average diameter of their flowers is 5 cm. What effect would selection have on flower diameter in this population of sunflowers? A. The average flower diameter may not change if the population is under disruptive selection. B. Small flowers are favoured if the population is under disruptive selection. C. The average flower diameter will increase if the population is under stabilizing selection. D. Large flowers are favoured if the allele for flower size is dominant when the population is under directional selection.arrow_forwardWhich hypothesis is plausible for the extinction of the dodo bird? Select all answers that apply. A. The food and other resources they required became scarce due to climate change. B. An asteroid crashed into the region where the birds lived and only affected their survival and not the other animals that lived there. C. Cannibalism within the species caused the population to decline. D. Each bird dove into the water even though it could not swim, which led to mass drownings. U E. Predators, including humans, hunted and killed the population to a point that it could not recover. red MacBook Air 80 F3 F1 DO0 F4 F2 F5 F7 % & %24 23arrow_forward
- Assume you are studying the fossil record of a certain lineage of sharks. You find that sharks in this lineage will maintain the same morphology for long periods of time and only rapidly change their morphology during a speciation event. The evidence you uncover is supportive of which of the following theories? a. Punctuated Equilibrium b. Gradualism c. Start and Stasis d. Increased Net Tempoarrow_forwardBehavioral ecology assumes a. that all behavioral traits are innate. b. learning is the dominant determinant of behavior. c. behavioral traits are subject to natural selection. d. behavioral traits do not affect fitness.arrow_forwardWhen taking the question, it would appear as: Consider global warming, a continual gradual increase in average temperatures. How might you expect this to affect natural selection? A.environmental changes are unpredictable, and natural selection is a random process, so it is difficult to predict outcome B.species from warmer climates are likely to expand their ranges into higher latitudes C.traits that increase reproductive success under warmer temperatures are likely to increase in frequency in a population D.the stress caused by higher temperatures will increase mutation ratesarrow_forward
