Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.

Which best describes the role of mutations in natural selection?

• Mutations help an organism to better survive in their environment
• An organism may acquire a helpful mutation by interacting with the environment
• A mutation may result in an adaptive trait that makes an organism more likely to survive and reproduce
• Organisms with certain traits are more likely to win competitions for mutations

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

• Variation
• Adaptation
• Behavior
• Environment

Organisms with the most beneficial traits will survive.  This is commonly known as

• theory of evolution.
• variations.
• survival of the fittest.
• ecosystems.

The graphs below show the changes in crab color at one beach.

Which of the following is most likely to have caused the change in the distribution?

• A new predator arrived that preferred dark-tan crabs.

• A new predator arrived that preferred light-tan crabs.

• A change in beach color made medium-tan crabs the least visible to predators.

• A change in beach color made medium-tan crabs the most visible to predators.
