Question

how has the study of mitosis affected scientists knowledge of cancer? it led to a study of how to induce cancer cells to divide more rapidly. it led to an understanding of how cancer cells divide so rapidly. it led to the development of contact - inhibition regulators. it led to the discovery of how to prevent cancer cells from dividing.

Explanation:

Mitosis is the process of cell division. Cancer cells divide rapidly. Studying mitosis helps understand the mechanisms of cell division. This understanding can be applied to cancer cells. Option 2 is correct as it aligns with the knowledge gained from studying mitosis - understanding the rapid division of cancer cells. Option 1 is incorrect as we don't want to induce more rapid division. Contact - inhibition regulators (option 3) are not directly a result of mitosis study in this context. We haven't discovered a way to completely prevent cancer cell division (option 4) through mitosis study alone.

Answer:

It led to an understanding of how cancer cells divide so rapidly.
