Which of the following statements best describes what will most likely occur to the moth populations in
the image below? - ANSWER✔ The light moths will be captured by predators more easily than the
dark moths, and the population of dark moths will rise.
Explanation: The light moths are highly visible to predators against the dark tree, but the dark moths are
nearly invisible to predators. So, it is likely that more light moths will be captured by the predators,
causing the population of light moths to decrease. The dark moth population will increase because there
are more of them to reproduce.
What is the most likely explanation of the data shown below? - ANSWER✔ The moths are living in an
environment with dark trees.
Explanation: Since the population of dark moths is rising and the population of the light moths is falling,
you can assume that the dark moths have some sort of advantage over the light moths. If the trees in
their environment were dark, that would be an advantage to the dark moths, because they would be
better camouflaged on the dark trees.
The pair of population graphs below display the results of two different five-year hunting cycles, one on
light trees and one on dark trees. The population of light-colored moths is shown by the light gray dots,
and the population of dark moths is shown by the dark gray dots. How do these results demonstrate
natural selection? - ANSWER✔ The moths that were the same color as their background were more
likely to survive and reproduce. Over time, the populations of these well-adapted moths increased.
Explanation: The graphs show that the populations of moths that were the same color as the trees
increased, while the populations of moths that were the opposite color as the tree decreased. The
moths that were the same color as the trees were better hidden and less likely to be eaten by birds.
These moths were more likely to survive and produce offspring. Over time, the populations of well-
camouflaged moths increased, and poorly-camouflaged moths died out.
Suppose a certain species of insect lives in the lush green canopy of the rain forest. Some of the insects
are bright green in color, and some are bright yellow. Assume there is a natural predator of the insect in
the area. What do you expect to happen to the populations of the green and the yellow insects over
