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 increases 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 cause changes (mutations) in DNA. Cancer develops when uncontrolled cell growth occurs due to accumulated DNA mutations. Increased exposure to mutagens raises the chance of DNA mutations, which in turn elevates the risk of cancer.

Answer:

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