Question 7

What word describes a trait that helps an organism survive in its environment?

Accepted Answer

adaptation

Answer

natural selection

Answer

mutation

Answer

camouflage

Question 8

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

Accepted Answer

Because they are more likely to survive and reproduce.

Answer

Because they come from dominant alleles.

Answer

Because they come from recessive alleles.

Question 18

A population of birds with various size beaks eats seeds. Small seeds can be eaten by birds with small beaks. Larger, thicker seeds can only be eaten by birds with larger, thicker beaks. During a drought, only large thick seeds exist so only the large, thick-beaked birds survive.

Accepted Answer

Directional

Answer

Stabilizing

Answer

Disruptive

Question 19

Women often have complications during labor while giving birth to very large babies, whereas very small babies tend to be underdeveloped. As a result, medium sized babies are the ones that end up surviving to adulthood.

Accepted Answer

Stabilizing

Answer

Directional

Answer

Disruptive

Question 20

Black rabbits (BB) and white rabbits (bb) are both able to survive because they can camouflage into the white and black rocks in their environment. However, the intermediate gray rabbits (Bb) do not survive. This results in only white and black rabbits.

Accepted Answer

Disruptive

Answer

Stabilizing

Answer

Directional

Question 21

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?

Accepted Answer

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

Answer

A new predator arrived that preferred dark-tan crabs.

Answer

A new predator arrived that preferred light-tan crabs.

Answer

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

Question 22

Which of the following best illustrates natural selection?

Accepted Answer

An organism with favorable genetic variations will tend to survive and breed successfully.

Answer

A population monopolizes all of the resources in its habitat, forcing other species to migrate.

Answer

A community whose members work together utilizing all existing resources and migratory routes.

Answer

The largest organisms in a species receive the only breeding opportunities.

Answer

There has been a drought in the area that is affecting all life forms.

Answer

The population of natural predators of the moths has gotten smaller.

Answer

The moths are living in an environment with light trees.
