  Result in variation among organisms
- B.
  
  Occur in body cells instead of egg or sperms
- C.
  
  Are important unless the environment changes
- D.

- E.
  
  They are created by mutagens
4.

Mutations are (Standard 3.1d):

  Random chance events that can be passed on to offspring if they occur in gametes
- B.
  
  Nonrandom events that can be passed on to offspring if they occur in gametes
- C.

- D.
  
  Nonrandom events that can be passed on to offspring if they occur in somatic cells

5.

Which statement best explains the decreased effectiveness of an insecticide (Standard 3.1e)?
- A.
  
  The insecticide caused mutations that resulted in immunity in the mosquito.
- B.
  
  Mosquitoes resistant to the insecticide lived and produced offspring.
