Science 7.13D & 8.13C Quiz

What is natural selection? (Reminder: Natural selection happens without human influence.)

• When humans choose which organisms reproduce.

• When traits are passed down without human influence.

• When organisms choose their own traits.

• When traits appear randomly with no pattern.

What is artificial selection? (Reminder: Artificial selection is controlled by humans.)

• When organisms adapt to their environment naturally.

• When organisms evolve without human involvement.

• When humans breed organisms to have desired traits.

• When only the weakest organisms survive.

Which of the following is an example of natural selection? (Reminder: Natural selection happens in nature without human help.)

• Farmers breeding cows to produce more milk.

• A faster cheetah catching more prey and surviving.

• Scientists cloning animals for research.

• A dog breeder selecting the smallest puppies to breed.

Which of the following is an example of artificial selection? (Reminder: Artificial selection means humans are involved in choosing traits.)

• Birds with better camouflage surviving in the wild.

• Dogs being bred for specific coat colors.

• Trees growing taller to reach more sunlight.

• A cactus developing thicker stems to store water.

What is the main difference between artificial and natural selection? (Reminder: Artificial selection is human-driven, while natural selection occurs without human involvement.)

• Natural selection happens quickly, and artificial selection is slow.

• Natural selection requires human intervention, while artificial selection does not.

• Artificial selection is controlled by humans, while natural selection happens without human influence.

• Artificial selection occurs only in wild animals.

Why do some traits become more common in a population over time?

• Traits that help survival are passed on to offspring.

• Traits appear randomly and stay the same.

• All organisms in a population have the exact same traits.

• Traits disappear if they are not chosen by humans.

Which of the following is a benefit of artificial selection? (Reminder: Artificial selection helps humans create desirable traits.)

• It helps animals survive better in the wild.

• It allows humans to produce plants and animals with desirable traits.

• It makes organisms more resistant to natural changes.

• It prevents any variation within a species.

How does natural selection lead to evolution over time? (Reminder: Natural selection happens over many generations as traits that help survival become more common.)

• It allows organisms with favorable traits to survive and reproduce.

• It causes all organisms to become identical.

• It immediately changes an organism’s DNA.

• It prevents any new traits from appearing.

Why might a trait created by artificial selection not be beneficial in the wild? (Reminder: Artificial selection does not always consider survival in nature.)

• The trait may not help the organism survive natural conditions.

• Artificial selection only creates harmful traits.

• The trait always makes an organism stronger.

• Artificial selection produces traits that last forever.

A group of wild rabbits varies in fur color. Over generations, the rabbits with fur that blends into their environment survive more often than those with bright fur. What is happening? (Reminder: Natural selection occurs when traits that help survival become more common.)

• Artificial selection is causing the color change.

• The rabbits are choosing their own fur color.

• Natural selection is favoring the better-camouflaged rabbits.

• The environment has no effect on the rabbits.
