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

Which of the following is natural selection?When a pregnancy is terminatedWhen humans adapt to their environment, e.g. by wearing clothes for warmthWhen a mutation in an organism that makes it better suited to its environment is passed on to the next generationWhen animals or plants are bred by humans to produce desired characteristics

MULTIPLE CHOICEWhich of the following best describes natural selection?A the process by which organisms adapt to their environment through mutationsB the mechanism of beneficial traits in a population being passed to offspringC the deliberate selection of desirable traits in domesticated animals by humansD the random change in common traits within a population over time

Which of the following is natural selection?When a pregnancy is terminatedWhen animals or plants are bred by humans to produce desired characteristicsWhen humans adapt to their environment, e.g. by wearing clothes for warmthWhen a mutation in an organism that makes it better suited to its environment is passed on to the next generation2Why did the black peppered moth become more prevalent than the white peppered moth during the industrial revolution?The black peppered moth ate the white peppered mothThe black peppered moth could fly faster and therefore escape predatorsThe black peppered moth was better camouflaged against polluted tree barkThe white peppered moth was killed by pollution3Natural selection within a species occurs when advantageous genetic mutations are passed on to the next generation. Which of the following is the best explanation for why this happens?Mutations cause changes in the environment that make breeding more successfulThe mutation can be passed from individual to individual by pathogensIndividuals with the mutation can escape predators more easilyIndividuals with the mutation are more likely to survive and breed successfully 4Why can bacteria evolve more quickly than other species?They are simple unicellular organismsThey reproduce at a fast rateThey are resistant to antibioticsThey have been around for millions of years

Natural selection occurs whenMultiple Choicewhen a small number of individuals of a population break away and form a new population.a factor in the environment alters the genetic information in DNA of all members of a species.only when nonrandom mating occurs.a new genetic variation occurs that allows individuals to have a reproductive and survival advantage.

Natural selection within a species occurs when advantageous genetic mutations are passed on to the next generation. Which of the following is the best explanation for why this happens?Individuals with the mutation can escape predators more easilyThe mutation can be passed from individual to individual by pathogensMutations cause changes in the environment that make breeding more successfulIndividuals with the mutation are more likely to survive and breed successfully
