Question

question 50 (multiple choice worth 2 points) some products have been identified as mutagens. however, some tobacco users develop cancer and some do not. the reason for this apparent inconsistency is: option 1: tobacco use only causes benign tumors that are identified as non - cancerous. option 2: not all tobacco products are cancerous. option 3: some people are more predisposed to developing cancer when exposed to mutagens. option 4: mutagens only have the capability to cause mutations if exposure lasts over 20 years.

Explanation:

Cancer - development is a complex process. Mutagens can cause mutations, but whether cancer develops also depends on individual genetic - predispositions. Some people have genetic factors that make them more or less likely to develop cancer when exposed to mutagens like those in tobacco.

Answer:

C. Some people are more predisposed to developing cancer when exposed to mutagens
