Question

nutrient absorption occurs as the direct result of which cellular process?
diffusion
cellular respiration
defecation
peristalsis

Explanation:

Diffusion is the movement of substances from an area of higher concentration to an area of lower concentration. In the context of cells, nutrients can move across the cell - membrane through diffusion, allowing for nutrient absorption. Cellular respiration is about energy - production, defecation is the elimination of waste from the body, and peristalsis is the muscular movement in the digestive tract for food movement, not direct nutrient absorption at the cellular level.

Answer:

A. Diffusion
