a. are born first and grow fastest  b. are largest and most aggressive  c. are best adapted to the environment  d. have no natural predators

19. 18. One concept that supports the theory of evolution states that organisms best adapted for survival are the ones that will reproduce and pass traits on to future generations. Adaptations that can be passed on do not include
 a. techniques for hunting food taught by the parents of the organism  b. the reflex actions of the organism  c. the manner in which the organism carries out respiration  d. the basic structure of the organism

20. 19. Many biologists believe that the great number of different species of organisms which exist on the planet and the present time has resulted from billions of years of
 a. gel electrophoresis  b. evolution  c. cloning  d. recombinant DNA

21. 20. What is the most probable reason that fossils found in lower layers of undisturbed rock are not found in upper layers of undisturbed rock in the same rock sequence?
