Multiple Choice

What is an adaptation?

• A skill that is learned during an organism's life

• A temporary change in an organism's behavior

• An inherited trait that increases an organism's chance of surviving and reproducing

• A physical change that occurs in response to a temporary environment

Multiple Choice

Why are adaptations important for populations?

• Adaptations have no impact on survival
• Adaptations make individuals weaker
• Adaptations help individuals survive

• Adaptations decrease genetic diversity

Multiple Choice

What could happen to a population that cannot adapt?

• It will become dominant

• It will increase in number

• It will migrate to a different habitat

• It will go extinct

Open Ended

What purpose does white fur serve for an animal in a snowy environment?

Multiple Choice

Which mutations are more likely to be passed on to future generations?

• Not favorable mutations

• Favorable mutations

• Mutations that occur in offspring.

• All mutations

Multiple Choice

What is genetic variation?

• The process by which new species are created.

• The study of genes and their functions.

• The natural differences within a species.

• The intentional breeding of species to produce desired traits.

Multiple Choice

Which of the following is an example of genetic variation?

• Different fur length in dogs

• Different blood types in humans

• Different coat colors in wolfs

• All of these

Multiple Choice

What is natural selection?

• A process where only the strongest organisms survive

• A method of artificial breeding in organisms

• A process where organisms evolve through favorable traits that help them survive and reproduce

• A theory that all organisms have the same chance of survival

Multiple Choice

What is a favorable trait?

• A trait that makes an organism less likely to survive and reproduce

• A trait that gives an organism an advantage to survive and reproduce

• A trait that is common in all organisms

• A trait that an organism can learn during its lifetime

Multiple Choice

What does the Theory of Evolution state about the origin of life on Earth?

• life on Earth was created simultaneously.

• life on Earth has remained unchanged since its beginning.

• life on Earth developed from preexisting life over time.

• life on Earth came from another planet.

Multiple Choice

What contributed to the different beak shapes of finches on the Galapagos Islands?

• Natural selection and

  variations in beak size and shape

• Climate change and habitat destruction
• Genetic engineering and artificial selection
• Random mutations and environmental pollution

Multiple Choice

Why is a population with a lot of genetic variation considered more stable?

• It has a higher chance of having individuals that are adapted to new conditions.

• It can change the environment to suit its needs.

• It is less likely to interact with other populations.

• It has a lower chance of survival.

Multiple Choice

What are the possible outcomes for a population when the environment changes?

• Adaptation, migration, or extinction

• Mutation, adaptation, or extinction

• Hibernation, adaptation, or migration

• Adaption, mutation, or migration

Multiple Choice

In the forest there are two types of moths. One is a light gray and the other is a dark brown. The light gray moths blend in with the light gray trees while the dark brown moths stand out. What would happen to the population if pollution caused the trees to darken?

• The population of dark brown moths would increase while the population of light gray moths would decrease.
• The population of dark brown moths would decrease while the population of light gray moths would also decrease.
• Both populations of moths would increase due to the change in tree color.
• The population of light gray moths would increase while the population of dark brown moths would decrease.
