   This review is intended to reflect the
general material as presented in the lab
documents and does not take into account
specific emphases that individual professors
may or may not stress. Always check with
your professor for any clarifications.
                   Geologic Time-line

                    Half Life
   Assume a half life is 5,730 years.
   A fossil has 1/16 the Carbon 14 compared to
    when it was living.
   How many half lifes have occurred?
   Answer: (½)n where n = the number of half
    lifes. ½ x ½ x ½ x ½ = 1/16 = four half lifes.
   What is the age of the fossil?
   Answer: 5,730 yrs./half life x 4 half lifes =
    22,920 yrs.

   125 students out of 500 have an unattached ear which is
    recessive. Determine p, q, p2, q2 and 2pq.
