    C.      nervous system, brain, nervous tissue, nerve cell
  29. Which of the following is not an observation or inference on which Darwin's theory of natural selection is based?

  30. Systems biology is mainly an attempt to




    D.      understand the behavior of entire biological systems.
  31. Protists and bacteria are grouped into different domains because




    E.      protists have a membrane-bounded nucleus, which bacterial cells lack.
  32. Which of the following best demonstrates the unity among all organisms?




    D.      the structure and function of DNA
