Group of answer choices
a.Variations between individual organisms lead to differential survival chances.
b.The conditions in an ecosystem support a wide range of living organisms

- Which of the following is the best description of sexual selection? a. Sexual selection is the differential reproductive success due to variation in acquiring immunity from mates. b. Sexual selection is the differential reproductive success due to variation in survival from social selection. c. Sexual selection is the differential reproductive success due to variation in acquiring mates or mating success. d. Sexual selection is the differential survival success due to variation in avoiding mates or mating success.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_forwardDarwinian fitness is a measure of a. survival. b. reproductive success. c. heterozygosity of the gene pool. d. polymorphisms in a population.arrow_forward
- Which of the following statements about natural selection is a misconception? a.Most species don't produce more offspring than the environment can support b.Natural selection acts on heritable variations in a population c.Natural selection involves differential reproductive success d.Natural selection occurs as a result of competition among individuals in a population e.In natural selection, traits that are favoured depend on current environmental conditionsarrow_forwardAlfred Russel Wallace and Charles Darwin argued that evolution by means of natural selection involves all of the following steps except: a. variation is present in all species b. species can produce more offspring than the environment can sustain c. all individuals within a species have equal chances to improve their fitness d. those individuals that are more fit will survive and reproduce in the greatest numbers e. over time, the species will evolve as the more fit individuals replace the less fit individualsarrow_forwardYour 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? A. overproduction of offspring leads to a struggle for survival 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 disappearancearrow_forward
- Indicate whether each of the following statements about natural selection is true (T) or false (F). Put either a T or an F in each box provided. a. Natural selection alters a population's gene pool b. Natural selection creates new alleles which increase the reproductive success of their owners c. Natural selection favors traits which it anticipates will be beneficial to a species in the future d. Natural selection can at times be observed in nature over the course of just a few decades e. Natural selection acts directly on an individual's phenotypearrow_forwardWhat is the difference between evolution, natural selection, and artificial selection? A. Evolution is a genetic change in a population over time which can occur through natural selection. Artificial selection is the differential reproduction of individuals in a population to promote the characteristics chosen by the breeder. B. Natural selection is the change of allele frequencies in a population over time. Evolution leads to differential survival and reproduction of individuals. Artificial selection has produced domesticated animals and plants. C. Evolution is a mechanism of artificial selection. Natural selection is a form of artificial selection in which nature selects the characteristics that are most beneficial to a species. D. Artificial selection is a mechanism of evolution and is the main process of domesticating animals and plants for human use. Natural selection is the same as evolution.arrow_forwardWhich of the following best explains the role mutations play in natural selection?A. Most mutations are negative and result in the extinction of the entire speciesB. Mutations may appear for one or two generations, but they usually disappear quickly.C. If the environment changes, an existing organism develops a mutation that will help them to survive.D. Some mutations give individuals an advantage in their environment, allowing them to survive and reproduce.D is my answer is it correct?arrow_forward
- Which of the following statements is true? A. Evolution involves a change in gene frequencies from one generation to the next B. Natural selection is the only mechanism through which animals evolve to become adapted to their environment C. Genetic drift results in evolution but not adaptation to the environment D. For natural selection to occur, differences in genetically-based traits must result in differential reproductive success E. All of the above are true A blastopore... A. Is the opening through which food enters a gastrovascular cavity B. Is an opening to the water-filled central cavity of a sponge C. Is the opening to the primitive gut that gives rise to the mouth in a deuterostome eucoelomate D. Is the open end of the archenteron that appears during gastrulation E. None of the abovearrow_forwardUnder 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.
