Question

b. why do skin cells divide more frequently than liver cells?

Explanation:

Skin cells are constantly exposed to external factors like abrasion, damage, and environmental stress. They need to be replaced quickly to maintain the integrity of the skin barrier. Liver cells, on the other hand, have a more stable internal environment and are not as frequently damaged, so they divide less often.

Answer:

Skin cells are more exposed to damage and need to be replaced rapidly to keep the skin barrier intact, while liver cells have a more stable environment and are less frequently damaged, thus dividing less often.
