Select all that applySelect observations and inferences that Charles Darwin made in support of natural selection.Multiple select question.Natural selection can change the characteristics of a population over many generations.Organisms are varied and some variations are inherited.Individuals in a population share all of the same characteristics; thus, no variation can occur in future generations.Some individuals survive due to their inherited characteristics, making them more likely to reproduce.There is competition among individuals for limited resources.More individuals are born than can survive to reproduce.Resources are usually available in unlimited supply.

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.

Darwin noted that natural selection occurs becauseMultiple choice question.the sick and weak individuals in a population pass on their traits at the same rate as the healthy.adaptive traits that are heritable can pass to offspring and increase their survival and reproduction.an individual can adapt their behavior or morphology in their lifetime and pass the adaptation on to their offspring.resources are so abundant in a population that competition is not a part of natural systems.

Select all the reasonings of Charles Darwin that were influenced by Thomas Malthus's essay.Multiple select question.All members of a population are well-adapted to obtaining resources.More individuals are born into a population than the habitat can support.Some individuals in a population are better able to obtain resources than others.All individuals in a population can adapt to the habitat.There is variation in a population.

In his book On the Origin of the Species, Charles Darwin described how species change over time. Which of the following is NOT part of his observations that describes the mechanisms of natural selection? Group of answer choicesDisease and natural disaster will limit population growth.Species today descended with modifications from ancestral species.Organisms produce more offspring than can survive.Organisms with advantages will survive and reproduce.

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.
