Final answer:
The correct answer is D) Cell division. When a cell is treated with a drug that prevents cell division, it inhibits the process of mitosis, which is essential for the replication and division of cells.
Step-by-step explanation:
The correct answer is D) Cell division. When a cell is treated with a drug that prevents cell division, it inhibits the process of mitosis, which is essential for the replication and division of cells. Without cell division, the growth and development of an organism would be hindered, as new cells cannot be formed to replace old or damaged ones.
