Question

which statement best describes cancer cells? they grow as a single layer of cells. they cease to reproduce after 20 - 50 mitotic divisions. they reproduce only when needed to replace missing cells. they are not regulated by contact inhibition.

Explanation:

Normal cells stop growing when they come into contact with other cells (contact inhibition). Cancer cells lack this regulation and can keep growing and dividing uncontrollably. They do not grow as a single - layer, can divide far more than 20 - 50 times, and do not reproduce only when needed to replace missing cells.

Answer:

They are not regulated by contact inhibition.
