• Variation
• Adaptation
• Behavior
• Environment

Scientist have created larger and sweeter strawberries for humans to consume (eat). What process was used?

• Natural Selection 
• Artificial Selection 
• Cellular Respiration

Which type of reproduction will produce offspring that are genetically identical to the parent organism?

• sexual reproduction
• asexual reproduction
• both
• neither

Why does the Hood mockingbird have a longer beak than the other mockingbirds?

• The beak stretched to reach its food
• It's an adaptation
• The Hood mockingbird came from a different bird species
• The Hood mockingbird uses it for defense

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

Why might it be helpful for a species to have a lot of variations?

• They can't be seen by predators

• If the environment changes, they might be better able to adapt

• It is helpful in asexual reproduction

• They don't recognize each other
