Quiz #11 - Mutations and Adaptations

Can mutations be harmful?

• Yes, mutations can be harmful, beneficial, or neutral depending on their effects on the organism.

• No, mutations are always harmful.

• Mutations have no effect on organisms.

• All mutations are beneficial.

What is a mutation?

• A change in the DNA sequence of an organism that can lead to new traits.

• A process that eliminates genetic variation in a population.

• A method of cloning organisms for research purposes.

• A technique used to enhance the growth of plants.

Why do some plants have thorns?

• To attract pollinators

• To store water

• To protect themselves from animals that want to eat them

• To enhance photosynthesis

What is the difference between physical and behavioral adaptations?

• Physical adaptations are actions or behaviors that help survival, while behavioral adaptations are structural features.

• Physical adaptations are structural features, while behavioral adaptations are actions or behaviors that help survival.

• Physical adaptations are temporary changes, while behavioral adaptations are permanent changes.

• Physical adaptations are features that do not change, while behavioral adaptations are features that change over time.

What is a behavioral adaptation?

• A change in behavior that helps an organism survive, such as migration in birds.

• A physical change in an organism's body structure, like the development of thicker fur in cold climates.

• A genetic mutation that occurs over generations to improve survival.

• A learned behavior that is not instinctual, such as using tools.

What does it mean for a mutation to be neutral?

• A neutral mutation significantly enhances the organism's ability to survive or reproduce.

• A neutral mutation has no effect on the organism's ability to survive or reproduce.

• A neutral mutation is harmful to the organism's survival and reproduction.

• A neutral mutation causes a drastic change in the organism's traits.

What is camouflage?

• A type of clothing worn by soldiers.

• A method of communication among animals.

• A type of adaptation that allows an organism to blend in with its environment to avoid predators.

• A technique used in art to create illusions.

Give an example of a physical adaptation.

• White fur on a polar bear is a physical adaptation that helps it blend in with its snowy environment.

• Long neck of a giraffe allows it to reach high leaves on trees.

• Bright colors of a poison dart frog warn predators of its toxicity.

• The thick skin of an elephant protects it from harsh weather.

What is an example of a harmful mutation?

• Developing cancer is an example of a harmful mutation.

• Increased height due to a genetic mutation.

• Enhanced vision from a genetic change.

• Resistance to common colds due to a mutation.

What is an adaptation?

• A type of food that organisms eat.

• A characteristic or trait that helps an organism survive and reproduce in its environment.

• A method of communication between species.

• A seasonal change in an organism's behavior.
