    • B. 

      Migration

    • C. 

      Mutation

  • 2. 
    What are the 3 conditions for natural selection to occur?
    • A. 

      More organisms are produced than can survive and reproduce.

    • B. 

      The fittest individuals are more likely to survive and reproduce.

    • C. 

      Humans must be able to control breeding practices.

    • D. 

      There must be variation within a species, and some of those variations must be better adapted to a particular environment.

  • 3. 
    What is an adaptation?
    • A. 

      A heritable trait that increases the ability to survive and reproduce in an environment

    • B. 

      A heritable trait that does not affect the ability to survive and reproduce in an environment

    • C. 

      A heritable trait that increases the ability to survive and reproduce in ALL environments

  • 4. 
    Mimicry is an adaptation where
    • A. 

      An organism imitates the environment in an effort to blend in and hide

    • B. 

      One organism imitates a more dangerous organism

    • C. 

      An organism has a behavior that allows it to better survive

  • 5. 
    Camouflage is an adaptation where
    • A. 

      An organism imitates the environment in an effort to blend in and hide

    • B. 

      One organism imitates a more dangerous organism

    • C. 

      An organism has a behavior that allows it to better survive

    • D. 

      Animals bury their heads in sand

  • 6. 
    Some behaviors are inherited and are more or less likely to help an organism survive.
    • A. 

      True

    • B. 

      False

  • 7. 
    What is fitness?
    • A. 

      Ability to survive and reproduce in a given environment

    • B. 

      Ability to survive in a given environment - reproduction is not a part of the definition

    • C. 

      Ability to survive and reproduce in all environments

  • 8. 
    Which organisms will be survive and reproduce if natural selection is working?
    • A. 

      Organisms with variations that farmers choose as most desirable

    • B. 

      Organisms with variations most suited to their environment

    • C. 

      Organisms who are biggest

  • 9. 
    What is the difference between artificial selection and natural selection?
    • A. 

      The difference is who chooses which organisms reproduce: in artificial, it is a person, in natural, it is the environment.

    • B. 

      One occurs only in laboratories, although it mimics what happens in the natural world

    • C. 

      Artificial selection is fake and natural selection is real
