A. Dark moth
B. Light moth
C. Both will be equally successful
D. Neither will be successful
Ostrich wings are examples of
A. homologous structures

D. sonic hedgehog gene
Survival of the fittest or when favorable adaptations reproduce faster is called what?
C. Natural selection
A population of rabbits grows rapidly from one year to the next. Then one year, a disease strikes approximately one fourth of the adult rabbits. The disease remains with the population in the years that follow.
As explained by Darwin’s theory, which of these conditions allows the rabbit population to evolve by natural selection?
A. The disease affects adult and juvenile rabbits equally.
B. The disease reduces the ability of the rabbits to reproduce.
C. Some rabbits are resistant to the disease, and they pass the resistance to their offspring.
D. No rabbits are resistant to the disease, and all die when the disease strikes them.
Which of these is an example of natural selection?
A. The largest animal in a population will have more opportunities for reproduction.
B. Several species of organisms work together so that they all succeed.
C. One species takes all the resources in an environment leaving none for others.
D. Organism that are best suited to an environment tend to survive and reproduce more often.
Which of the following statements best describes what will most likely occur to the moth populations in the image above?
A. The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.
B. The light moths will be captured by predators more easily than the dark moths, and the population of light moths will rise.
C. The dark moths will be captured by predators more easily than the light moths, and the dark moths will probably go extinct.
D. The light moths will change their wing color to match that of the dark moths.
