Question

which of the following describes cancer?
a. mutations in the dna cause a cell to die prematurely due to apoptosis.
b. mutations in the dna cause a cell to divide more often than it should.
c. mutations in the dna cause a cell to be attacked by the immune system.
d. mutations in the dna cause a cell to produce harmful chemicals.

Explanation:

Cancer is characterized by uncontrolled cell division, which arises from DNA mutations that disrupt the normal regulation of cell growth and division. Option A refers to programmed cell death (apoptosis), which is the opposite of cancer cell behavior. Option C describes immune system attack, which can target some cancer cells but is not the defining cause of cancer. Option D is not the core defining feature of cancer. Only option B matches the key characteristic of cancer cells.

Answer:

B. Mutations in the DNA cause a cell to divide more often than it should.
