process that can move gases
requires extra energy, e.g. from atp
a passive process
movement from low to high concentration
movement of molecules
requires a semipermeable membrane
sometimes uses channel proteins

Explanation:

1. Movement from high to low concentration: Diffusion is the movement of substances (including gases and solutes) from an area of high concentration to low concentration. Osmosis is the diffusion of water from high - water potential (low solute concentration) to low - water potential (high solute concentration), also a high - to - low movement. So this applies to Diffusion and Osmosis.
2. Transport of water molecules: Osmosis is specifically the transport of water molecules across a semi - permeable membrane. Diffusion can also involve water molecules in a non - membrane context, but Osmosis is the main process for water molecule transport across membranes. So this applies to Osmosis.
3. Can transport solutes: Diffusion can transport solutes from high to low concentration. Active transport can also move solutes, often against the concentration gradient. So this applies to Diffusion and Active Transport.
4. Only uses carrier proteins: Active transport often uses carrier proteins to move substances against the concentration gradient. Some facilitated diffusion (a type of diffusion) also uses carrier proteins, but the statement says "only", so this mainly applies to Active Transport.
5. Process that can move gases: Diffusion is the process by which gases like oxygen and carbon dioxide move across cell membranes or in the body, from high to low concentration. So this applies to Diffusion.
6. Requires extra energy, e.g. from ATP: Active transport requires energy (usually in the form of ATP) to move substances against their concentration gradient. So this applies to Active Transport.
7. A passive process: Diffusion and Osmosis are passive processes as they do not require energy input and rely on the concentration gradient. So this applies to Diffusion and Osmosis.
8. Movement from low to high concentration: Active transport is the process that moves substances from an area of low concentration to an area of high concentration using energy. So this applies to Active Transport.
9. Movement of molecules: All three - Diffusion, Osmosis, and Active Transport involve the movement of molecules. Diffusion and Osmosis are passive molecule movements, and Active Transport is an energy - requiring molecule movement. So this applies to Diffusion, Osmosis, and Active Transport.
10. Requires a semi - permeable membrane: Osmosis requires a semi - permeable membrane for the movement of water molecules. Some forms of diffusion (facilitated diffusion) also require a membrane with transport proteins. So this applies to Osmosis and Diffusion (facilitated).
11. Sometimes uses channel proteins: Diffusion (facilitated diffusion) can use channel proteins to move substances (such as ions) across the membrane. Active transport can also use carrier proteins (which are different from channel proteins in some ways but still related to membrane transport). So this applies to Diffusion and Active Transport.
