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.

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.

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

Match the mechanism of natural selection with its corresponding description.the process by which individuals with advantageous traits have higher chances of survival and reproductionthe mechanism that allows genetic information to be passed down from parents to offspringthe period over which changes accumulate, leading to the emergence of new traits and the extinction of othersthe diverse range of traits exhibited among individuals within a populationthe outcome of natural selection, where populations become better adapted to their specific environmentsa.adaptationb.selectionc.timed.variatione.inheritance

Evolution through natural selection states that:Group of answer choicesspecies adapt and change over time based on pressure within their niche.an individual can change their genes within their own lifetime.species adapt based on their individual goals.individuals determine their own biological adaptations by trying hard enough they can succeed and base their altered genes on to their offspring.

How did Darwin explain the process of natural selection?a. Traits acquired during an organism's lifetime are passed on to offspringb. Individuals with unfavorable traits are more likely to survivec. Offspring inherit helpful traits that lead to better adaptationd. Overproduction of offspring ensures survival of the species
