Question

which accurately describes the relationship between cancer risk and exposure to mutagens?
cancer risk decreases when a person is exposed to mutagens because the risk of dna mutation decreases as
well.

cancer risk increases when a person is exposed to mutagens because the risk of dna mutations decreases
considerably.
cancer risk decreases when a person is exposed to mutagens because the risk of dna mutations increases
considerably.

Explanation:

Mutagens are agents that can cause mutations in DNA. Cancer often arises from mutations in genes that regulate cell growth and division. When a person is exposed to mutagens, the likelihood of DNA mutations increases. These mutations can disrupt normal cell - cycle control mechanisms, leading to uncontrolled cell growth (cancer). So, an increase in mutagen exposure leads to an increase in DNA mutation risk and thus an increase in cancer risk.

Answer:

Cancer risk increases when a person is exposed to mutagens because the risk of DNA mutations increases as well.
