How would you describe a horse population composed of horses of different colors?

• All of the horses have the same traits because they are in the same population

• The population of horses has different traits for color. Some horses are brown. Some are gray, some are black, and some are white

• None of the horses in the population have similar traits because they are all individuals.

• These horses must not be in a population because they have different traits.

• evolution

• histogram

Why do populations change over time?

• different traits are passed on depending on which traits are favored by the environment

• they mutate

• they lose abilities that are no longer useful

• variation

• generation

• distribution

How do genes determine an individual’s traits?

• Genes directly cause traits

• Genes are random and don’t lead to traits

• Genes give organisms the ability to change their traits.

• Genes are instructions for making protein molecules and protein molecules determine traits.

Where do the genes that determine an individual's traits come from?

• An individual can be born with any genes, since genes are random.

• Individuals grow genes specific to their environment.

• Parents pass their genes down to their offspring

• Parents choose which genes their offspring have when each individual is born

Why were the newts with the poison gene able to live longer than those newts without the poison gene?

• the newts with the poison gene were able to live longer than the other newts

• the newts with the poison live longer because they are able to reproduce more than the other newts

• both claims are correct

• neither claim is correct

Which is NOT an example of mutations allowing the population to survive the environmental change?

• a mutation for fur to protect against a change in the temperature

• a mutation in poison to protect against an increase of snakes in the environment

• an organism continuing to express the same genes regardless of changes in the environment
