Natural Selection - Survey

Which of the following is the correct definition of natural selection?

• All organisms have an equal chance of surviving and reproducing.

• Organisms with traits well suited to their environment survive longer and reproduce more than others.

• Individual organisms are able to change their traits in response to environmental changes.

• Organisms are able to pass on their best traits to offspring when the reproduce.

Which wild cat will likely have the best chance of surviving when their environment gets cold?

• the light tan cat

• the cat with the shortest legs

• the fastest cat

• the cat with the longest hair

What is the advantage of finches having different shaped beaks?

• To attract a mate.

• To be able to eat the food in their environment.

• To protect itself against predators.
• Have different weapons when fighting each other.

When an environment changes color, what will most likely happen?

• The population will get really large really fast.

• The organisms within the population will change colors to match the new environment.

• Organisms that blend in better to the new environment will survive and reproduce more often.

• The pressure will cause the DNA of organisms to mutate more frequently.

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

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection

• Variation

• Homeostasis

• Extinction

When nature "selects" a variation, that means that the trait:

• Is helping organisms survive longer than others.

• Causes the population to shrink

• Has brought about a new species

• Is being edited by nature.

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.

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

• natural selection

• mutation

• allele

• adaptation

This term describes the ability of one organism to survive and reproduce, based off the traits it inherited.

• fitness

• evolution

• natural selection

• gene
