Объяснение:

чем различаются диффузия и осмос?

Ответ: что это процесс проникновения двух веществ друг в друга в результате теплового (броуновского) движения молекул.

Answer 2

Diffusion and Osmosis

Diffusion and osmosis are both processes that involve the movement of molecules from an area of high concentration to an area of low concentration. However, there are some key differences between the two processes.

Diffusion is the movement of molecules or particles from an area of higher concentration to an area of lower concentration. It occurs due to the random motion of molecules and does not require any external energy input. Diffusion can occur in gases, liquids, and solids. It plays a crucial role in various biological processes, such as the exchange of gases in the lungs and the movement of nutrients and waste products across cell membranes.

Osmosis, on the other hand, is a specific type of diffusion that involves the movement of water molecules across a selectively permeable membrane. In osmosis, water molecules move from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration). The driving force behind osmosis is the difference in solute concentration on either side of the membrane. Osmosis is essential for maintaining the balance of water and solutes in cells and is involved in processes such as water uptake by plant roots and the regulation of fluid balance in animal cells.

In summary: - Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, while osmosis is the movement of water molecules across a selectively permeable membrane. - Diffusion can occur in gases, liquids, and solids, while osmosis specifically involves the movement of water molecules. - Diffusion does not require any external energy input, while osmosis is driven by the difference in solute concentration.
