Question

How diffusion is usefull in living beings?

Answer 1

Diffusion is important to organisms because it is the process by which useful molecules enter the body cells and waste products are removed. Digested food molecules move down a concentration gradient from the intestine to the blood.

Answer 2

Answer:

Explanation:

→ Diffusion of oxygen and carbon dioxide gas occurs in the lungs. Heat from the body diffuses away in the form of sweat that evaporates. The advantage of diffusion is that it does not require as much energy to regulate, as opposed to a cell having to make proteins that pump molecules across a membrane.
