Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

The use of pesticides on crops has been a common farming practice for decades. What has been the greatest effect of natural selection through the use of pesticides on certain insect populations?

• Natural selection has been altered because the insects and their predators are killed.

• The rate of selection is increased because the pesticides do not kill the insects that are naturally resistant to it.

• The rate of selection has decreased because the pesticides kill only young insects.

• The pesticides have altered natural selection by causing the insect DNA to spontaneously mutate.

Why were Lamarck's ideas on evolution incomplete? (Select ALL that apply)

• Individuals don't evolve, populations do

• Adaptation is caused by random mutation

• Only the fittest species will survive and reproduce

• Species have a tendency towards perfection

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.

Where do adaptations come from?

• The individual organism decides to adapt

• Mutations that give an organism an advantage in its environment

• Genetic recombination during meiosis

• Both mutations and genetic recombination are sources of adaptation
