4.

heritable differences

5.

A feature that allows an organism to better survive in its environment.

6.

1 point

When a small group of individuals colonize a new area, it is known as

convergent evolution

bottleneck effect

founder effect

genetic drift

7.

1 point

Divergent evolution is when closely related species evolve in different directions, and become increasingly different.

True

False

8.

1 point

Which of the following conditions does not mean the population is in Hardy-Weinberg equilibrium?

No natural selection

Random mating

Immigration happens

No mutations

9.

1 point

After many generations, an insect species evolved resistance to a particular pesticide. This occurred because spraying pesticides--

killed most of the insects in the population.

caused another insect species to go extinct.

caused mutations in the insect species' gene pool.

selected for insects that were able to survive and reproduce.

10.

1 point

The movement of alleles from one population to another is called

gene flow

sexual selection

genetic drift

speciation

11.

1 point

The similarity in forelimb structure of humans, bats, and moles is evidence that they --

use their forelimbs in similar ways.

share a common ancestor.

are members of the same genus.

evolved from each other.

12.

1 point

The wing of a bird and insect is an example of:

Divergent evolution

Punctuated equilibrium

Coevolution

Convergent evolution

13.

1 point

An Irish potato famine in the 1840s was caused by a fungus that infected the potato crop. This potato population was most likely vulnerable to infection due to a lack of--

Biological fitness is defined as

the percentage of energy that is dedicated to mating.

the average life span of an organism.

the amount of energy an organism can use in the environment.

the ability of an organism to survive and reproduce.

This type of selection is when humans select individual traits they desire, and then breed them to produce more individuals with those traits.

Reproductive isolation is when members of different populations can no longer mate successfully.

True

False
