LS4.3 Natural Selection TCAP Review

Based on the table, which inference about the relationship between symmetry and evolution is most accurate?

• Organisms with different types of symmetry are more closely related than organisms with the same symmetry.

• Organisms with the same type of symmetry may be more closely related than organisms with different symmetries.

• Organisms with radial symmetry evolved into organisms that are either asymmetrical or that exhibit bilateral symmetry.

• Organisms with bilateral symmetry evolved into organisms that are either asymmetrical or that exhibit radial symmetry.

A biologist in Nebraska discovers that deer mice living in sandy regions have lighter fur than deer mice living in forested areas (with darker soils) just a few kilometers away. Which statement best explains why the fur color of deer mice varies?

• Variation in fur color helps the mice avoid predators.

• Variation in fur color helps the mice locate more food.

• Variation in fur color helps the mice hunt more easily.

• Variation in fur color helps the mice stay warm during winter.

Which statement is true about genetic variation and species adaptation?

• Less genetic variation in a population has no effect on the probability of survival of a species during changing habitat conditions.

• Less genetic variation in a population provides a species with a greater probability of survival during changing habitat conditions.

• More genetic variation in a population provides a species with a greater probability of survival during changing habitat conditions.

• More genetic variation in a population has no effect on the probability of survival of a species during changing habitat conditions.

Young deer have reddish-brown coats covered with white spots. Their coat color helps them blend in with the trees in the woods where they live. What is an advantage of this adaptation?

• It helps the parents locate their young ones quickly.

• It helps the young deer stay warm in cold weather.

• It helps the parents find food in the woods quickly.

• It helps the young deer avoid being spotted by predators.

Examine the diagram of a plant commonly found in the deserts of North America. Which statement explains how the plant has adapted for survival in an environment with limited precipitation?

• The plant has spines on its “leaves” where birds can perch and prevent other animals from eating the plant.

• The plant has no roots which enables it to absorb water quickly from the ground when it rains for transport to the “leaves.”

• The plant is able to hold large amounts of water in its “leaves,” so it can survive periods of drought.

• The plant allows ants to live in its “leaves,” and the ants protect and provide nutrients for the plant.

The diagram shows the wings of a bat and a bird. The bone structure inside both the wings is very different, but the wings of both animals help them in flight. What can be concluded by a comparison of the wings?

• The organisms have a similar cellular structure.

• The organisms evolved from a common ancestor that could fly.

• The organisms developed through similar embryological stages.

• The organisms developed similar adaptations in similar environments.

Four species of finch (W, X, Y, and Z) with different food sources inhabit a coastal island. There is a disease that kills most of the trees that produce large, heavy seeds that are the primary food source for finch W. Shortly after the trees die, there is a population boom among a type of insect that makes its home in dead trees. These insects are the primary food source for finch Z. What is the most probable impact on the finch species on the island?

• The population of finch species W will decrease, and the population of species Z will decrease.

• The population of finch species W will decrease, and the population of species Z will increase.

• The population of finch species W will increase, and the population of species Z will decrease.

• The population of finch species W will increase, and the population of species Z will increase
