  4. prokaryotic cells
    the DNA is not separated from the rest of the cell by enclosure in a membrane-bounded nucleus (its also smaller)
  5. genome

    • Ex: ATP production of excess.
  7. positive feedback
  8. less common; the end product speeds up its
    production ; Ex: blood clotting
  9. taxonomy
    the branch of biology that names and classifies species, formalizes this ordering of species into groups of inc. breadth
  10. Three Domains of Life
  11. Bacteria, Archaea, eukarya

  13. Charles Darwin
    theory of natural selection
  14. deductive reasoning
