adaptations

Chameleons are reptiles that have the ability to hide from predators and prey by blending in with their environment. They can change the pattern and/or color of their skin. This ability is known as --

• natural selection

• imitations

• mimicry

• camouflage

In the Arctic there is often snow on the ground. Many Arctic animals are able to change their coloration. Which adaptation best helps an Arctic hare survive in its environment?

• thick, white fur
• ability to run fast
• ability to burrow
• a short, fluffy tail

Which foot has adaptations for surviving in a water environment?

• A
• B
• C
• D

Anything that helps an animal survive in its environment.

• counter-shading
• mimicry
• adaptation
• camouflage

What adaptation is represented by the image?

• Camouflage

• Beak Design

• Hibernation

• Seed Dispersal

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution

• Natural Selection

• Selective breeding

• Artifical Selection

Why are favorable (advantageous) traits more likely to be passed onto offspring?

• Organisms that have them are more likely to survive and reproduce.

• Favorable traits come from dominant alleles.

• Favorable traits come from recessive alleles.

• Because the trait is an acquired phenotype.

Which organisms are most likely to survive?

• the best adapted

• the fastest

• the strongest

• the most domesticated

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

Roseate Spoonbills have evolved to have wide, spoon-shaped beaks. How did this adaptation probably happen?

• individuals with wide beaks were more attractive to mates, and therefore reproduced more often

• humans liked how wider beaks looked, so we selectively bred birds with wider and wider beaks

• individuals with wider beaks confused predators that saw them, survived longer, and therefore reproduced more often

• individuals with wide beaks caught more food, lived longer, and therefore reproduced more often
