Question

chemicals used in chemotherapy treatments to fight cancer can also harm cells in hair follicles and bone marrow. what characteristic do these cells most likely share with cancerous cells? they form tumors. they spread through the blood. they divide rapidly. they contain a mutation.

Explanation:

Chemotherapy targets rapidly dividing cells. Cancer cells divide rapidly, and hair follicle and bone marrow cells also divide rapidly (e.g., hair follicle cells for hair growth, bone marrow cells for blood cell production). Tumor formation is specific to cancer cells, spreading via blood is metastasis (cancer - specific), and mutations are not a shared trait here as hair/bone marrow cells are normal (just rapid division). So the shared characteristic is rapid division.

Answer:

C. They divide rapidly.
