which best describes somatic mutations?
they are usually passed on to offspring.
they can cause different kinds of cancer.
they always result from point mutations.
they only occur in reproductive cells.

Explanation:

Somatic mutations occur in non - reproductive cells. They are not usually passed on to offspring (so the first option is wrong). They can be caused by various factors like radiation, chemicals etc., not just point mutations (so the third option is wrong). And they do not occur in reproductive cells (so the fourth option is wrong). Somatic mutations in cells can lead to uncontrolled cell growth, which is a characteristic of cancer.

Answer:

They can cause different kinds of cancer.
