Question

Is the following statement true or false: Simple diffusion occurs across a membrane when particles move from an area of low concentration to an area of high concentration?

1. True
2. False

Answer 1

Simple diffusion occurs across a membrane when particles move from an area of high concentration to an area of low concentration.

Step-by-step explanation:

True. Simple diffusion occurs across a membrane when particles move from an area of high concentration to an area of low concentration.

This movement is driven by the concentration gradient, which is the difference in concentration between the two areas.

Diffusion is a passive process that does not require energy.
