Two organisms that are closely related would be expected to have

completely different DNA sequence

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

divergence of two or more species from an existing one

combining of two species to form one with different traits

isolation that affects mating behaviors

timing of mating that prevents normal sexual selection

The nonpoisonous eastern scarlet snake has colored bands that resemble the poisonous coral snake. This selective adaptation provides the eastern scarlet snakes with...

Lamarck was an early scientist who studied the development of characteristics in organisms over time. Which of the following choices best describes his views on how organisms change over time?

Theory of acquired characteristics

Theory of relative fossil-dating

A population of mice is evenly divided into two groups, and each group is placed on an isolated island with no existing mouse population. Which statement best explains the difference in the mouse populations on Island A and Island B at the end of the 20 years?

Conditions on Island B favored the brown-furred individuals, while both fur colors were evenly advantaged on Island A.

The recapturing of mice on Island A and Island B was done differently.

On Island A, the allele for gray fur was dominant, while on Island B, the allele for brown fur was dominant.

More brown mice were in the half of the original population that was sent to Island B than in the group sent to Island A

Which situation would most likely result in the highest rate of natural selection?

Reproduction of organisms exhibiting genetic differences due to mutations and genetic recombination in a changing environment

Reproduction of organisms by asexual reproduction in an unchanging environment.

Reproduction of a species having a very low mutation rate in a changing environment.

Reproduction of organisms in an unchanging environment with little completion and few predators
