Which of the following statements are part of the
Theory of Natural Selection?

• Individual organisms change in response to their
  environment.
• Variations are found among the members of a
  species.
• Not all of the young in each generation will
  survive.
• If an organism uses a structure more the
  structure will be more developed and that trait
  can be passed on to their offspring.

dominant allele in a population. Over the next
two generations, the frequency of this allele
does not change. Which factor(s) below must be
true in order to maintain this equilibrium

• Random mating
