Individual cells do not survive for the entire lifetime of an organism because a. the enzyme telomerase is readily destroyed by the environment, resulting in cell death. b. dna replication is subject to errors that cause cell death. c. okazaki fragments disrupt protein synthesis, resulting in cell death. d. the repeating telomeric sequence of ttaggg interferes with normal dna replication and leads to cell death.

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
