Select the true statement about mutation and natural selection.Multiple choice question.Natural selection produces mutations.Mutations arise when a population needs to adapt.Natural selection acts on existing mutation.

Select the correct statement about natural selection.Multiple choice question.Natural selection produces new phenotypes when a species needs them.Natural selection does not have a goal of a perfect organism.Natural selection acts to produce successively more complex and bigger species over time.

Which statement about natural selection is true?Choose 1 answer:Choose 1 answer:(Choice A)   Natural selection happens because organisms in a population have variations in their inherited traits.ANatural selection happens because organisms in a population have variations in their inherited traits.(Choice B)   Natural selection occurs within an individual’s lifetime.BNatural selection occurs within an individual’s lifetime.(Choice C)   Natural selection can change traits in a population, but has no effect on genes.CNatural selection can change traits in a population, but has no effect on genes.

Which statement accurately describes the adaptations that result from natural selection.Multiple choice question.Natural selection does not always produce perfectly working adaptations, because it can only work on the genetic variation present in a population.Natural selection always produces perfectly working adaptations, because mutations will sooner or later provide the necessary variation for an adaptation to arise.Natural selection always produces perfectly working adaptations, because it has millions of year to work.

Mutation is an important evolutionary mechanism and occurs with a permanent change in a nucleotide sequence. Which statements about mutations are true? Select TWO correct answers.Select one or more:a.Mutations must occur in gametes in order to be passed onto offspring.b.Most mutations do not result in a phenotype that increases the individual's fitness.c.Mutations occur very rarely in organisms.d.All mutations are harmful.e.Mutations decrease genetic variation in a population.

Which of the following statements is true?Question 13Answera.Natural selection works on variation already present in a population.b.Individuals evolve through natural selection.c.Organisms evolve structures that they need during their lifetimed.Natural selection works on all genes.
