Natural Selection Quiz 1

Certain types of tree frogs live in habitats with a lot of green, leafy vegetation. What color of tree frog would have the best chance of passing on its traits to successive generations in this habitat?

• yellow

• green

• black

• blue

What does it mean if members of a population live long enough to reproduce?

• They will pass on unfavorable traits to future generations.

• They will produce fewer offspring in the next generation.

• They have the most favorable characteristics for their environment.

• They have unfavorable characteristics for their environment.

Which statement best explains why natural selection might favor bright colors in frogs that are not poisonous?

• A. Bright colors help frogs catch their prey.

• B. Bright colors make it easier for frogs to find mates.

• C. Bright colors make frogs more visible to their predators.

• D. Bright colors mimic poisonous frogs so predators avoid them.

What process determines which individuals within a species are most likely to reproduce and pass their genes to future generations?

• interspecific competition

• mutualism

• natural selection

• continental drift

Which of the following best explains why some species are able to survive major changes in the environment?

• Some species have variation within their phenotypes, giving individuals an advantage for surviving change.

• Some species are able to reproduce at a fast rate, creating large populations that ensure some individuals will survive.

• Some species have identical genotypes, making them immune to change in the environment.

• Some species are genetically similar, ensuring that they will reproduce offspring that will not change traits.

Four hundred beetles of the same species were sprayed with an insecticide. Several weeks later, nearly all the beetles were dead. A few, however, survived. Which statement best describes the future generations of these beetles?

• The surviving beetles will not pass on their favorable traits to future generations.

• The majority of beetles in future generations will also die from the insecticide.

• The beetles in future generations will have no immunity to the insecticide.

• The future generations of beetles will likely survive the insecticide if it is sprayed again.

The graph below shows the populations of dark- and light-colored moths over a 10-year period. Which statement below best describes how natural selection is demonstrated in this data?

• A. An environmental change did not occur. Light-colored moths were always favored.

• B. An environmental change occurred, which began to favor dark-colored moths.

• C. An environmental change did not occur. Dark-colored moths were always favored.

• D. An environmental change occurred, which began to favor light-colored moths.

The table below shows the number of rabbits living in an area of forest over 4 different generations. The table also breaks down their population size by fur color. Which statement below gives the best explanation of this data?

• A. Rabbits with black fur have a better chance of survival compared to the others.

• B. Rabbits with white fur have a greater chance of survival if the environment remains the same.

• C. Rabbits with brown fur have the greatest chance of passing on their traits.

• D. All the rabbits have the same likelihood of passing on their traits.
