Question

Which statement is true?

A. Diffusion is the movement from areas of high concentration to areas of low concentration. Osmosis is a type of simple diffusion.


B. Both osmosis and diffusion must occur through a semipermeable membrane.


C. Diffusion requires the use of energy, but osmosis does not.


D. Osmosis is the movement of gases such as oxygen and carbon dioxide. Diffusion is the movement of water.

Answer 1

A. Diffusion is the movement from areas of high concentration to areas of low concentration. Osmosis is a type of simple diffusion.

Step-by-step explanation:

The statement that is true is:

A. Diffusion is the movement from areas of high concentration to areas of low concentration. Osmosis is a type of simple diffusion.

Step-by-step explanation:

Diffusion is the movement of particles from an area of high concentration to an area of low concentration, driven by the concentration gradient. Osmosis is a special type of diffusion that involves the movement of water molecules across a semipermeable membrane from an area of high water concentration to an area of low water concentration.

Option B is incorrect because diffusion can occur through any medium, while osmosis requires a semipermeable membrane.

Option C is incorrect because both diffusion and osmosis are passive processes that do not require the use of energy.

Option D is incorrect because osmosis involves the movement of water molecules, not gases, while diffusion can involve the movement of different types of particles, including gases, liquids, and solids.
