How does exposure to chemicals that cause mutations increase the risk of developing cancer? carcinogens can cause mutations in genes. hazardous chemicals can damage proto-oncogenes. carcinogens can cause abnormal protein synthesis. the rate of cancer causing mutations increases with age. hazardous chemicals can damage tumor suppressor genes?

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
