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 can cause changes (mutations) in DNA. Cancer often develops due to accumulated DNA mutations. So, when a person is exposed to mutagens, the likelihood of DNA mutations increases, which in turn increases cancer risk. The option stating "Cancer risk increases when a person is exposed to mutagens because the risk of DNA mutations increases as well" aligns with this biological concept.

Answer:

The option "Cancer risk increases when a person is exposed to mutagens because the risk of DNA mutations increases as well" (the second option in the list).
