question 24 of 25
how are tumor cells different from normal cells?
a. tumor cells are haploid and other cells are diploid.
b. there are no chromosomes in tumor cells.
c. mitosis is not regulated in tumor cells.
d. tumor cells use meiosis to replicate.

Explanation:

Tumor cells are abnormal cells. Normal cells have regulated mitosis (cell division). Tumor cells, however, have unregulated mitosis. This means they divide uncontrollably. Option A is wrong because most tumor cells are diploid (like normal somatic cells). Option B is incorrect as tumor cells do have chromosomes. Option D is wrong since tumor cells use mitosis (not meiosis, which is for gamete formation) to replicate.

Answer:

C. Mitosis is not regulated in tumor cells.
