Natural Selection

The process where organisms best fit for the environment are more likely to survive and reproduce.

• natural selection

• adaptation

• hibernation

• selective breeding

• hybridization

In a population of desert plants, the timing of their blooming varies greatly. Some bloom early in the morning, others at mid-day, and others after dark. What environmental pressure might be an advantage for those plants that bloom after dark?

• there is an increase in the population of nocturnal pollinators

• there is a decrease in the strength of solar radiation

• there is an increase in herbivores that forage at night

• there is a decrease in water for root absorption

Mountain lions are large cats and the top predator in their habitat. A population of mountain lions may vary in several characteristics. If a prey becomes scarce, competition between mountain lions for food will increase. Which variation would provide an advantage to the individuals that possessed it?

• a spotted coat

• short fur

• long legs

• abundant whiskers

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.

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
