Answer 4

D Diffusion transfers particles from an area of high to low concentration.

Answer 5

The correct answer is D) Diffusion transfers particles from an area of high to low concentration.

Explanation:
Diffusion is the process by which particles move from an area of higher concentration to an area of lower concentration. It occurs naturally and does not require any cellular energy or protein channels. The movement of particles in diffusion is driven by the concentration gradient, which means that particles move from an area where they are more concentrated to an area where they are less concentrated until they become evenly distributed.

In contrast, the active transport of ions by the sodium-potassium pump, as shown in the picture, is a process that requires cellular energy, specifically ATP molecules. This pump actively moves sodium ions out of the cell and potassium ions into the cell, against their concentration gradients. It uses protein channels called pumps to transport the ions.

Therefore, diffusion and the active transport of ions by the sodium-potassium pump are different processes. Diffusion occurs passively, driven by the concentration gradient, while active transport requires cellular energy to move particles against their concentration gradient.
