Which of the following regarding requirements for natural selection is incorrect?Group of answer choicesa parent produces more offspring than the environment can sustainacquired characteristics in the parent can pass on to offspringspecific characters in offspring can be inherited from the parentfitness varies among offspring

Which of the following is not an observation or inference on which natural selection is based?Group of answer choicesSpecies produce more offspring than the environment can support.There is heritable variation among individuals.Individuals whose characteristics are best suited to the environment generally leave more offspring than those whose characteristics are less well suited.Poorly adapted individuals never produce offspring.

Which of the following is not a principle of natural selection?Group of answer choicesEvolution will occur as an organism gets older and learns moreIn every population, adaptations allow some organisms to survive and reproduce better than others.Organisms compete for limited resourcesMost species produce more offspring than will actually survive

The most essential element in natural selection is ______.Multiple choice question.a society increasing the amount and quality of agriculture---socializationa species changing the environment to reflect genetic variation---accommodationan individual being born into the "right" family---elitisma species adapting to the environment through random genetic variation---adaptation

Which of the following is natural selection?When animals or plants are bred by humans to produce desired characteristicsWhen a mutation in an organism that makes it better suited to its environment is passed on to the next generationWhen humans adapt to their environment, e.g. by wearing clothes for warmthWhen a pregnancy is terminated2What is selective breeding? When one species breeds with another speciesScreening of embryos to detect inherited disordersA process in which animals or plants are bred to produce desired characteristicsA natural process in which beneficial mutations are passed on from parent to offspring3How does selective breeding affect the gene pool of a species? It reduces variation within a speciesIt results in spontaneous mutations It increases variation within a speciesIt results in all individuals within a species having identical genotypes4What is a disadvantage of reduced variation within a species?   It is easier for a species to adapt to environmental changesIt is more difficult for a species to adapt to environmental changesIndividuals within a species will all look the sameDisease will be passed more easily between individuals within a species5Which of these is not a desired characteristic obtained through selective breeding?   Gentle nature in domestic dogsStrong, high-yield crops that mature quicklyBreathing problems in pug dogsHigh milk yield in dairy cows
