How is osmosis diffirent from difussion?

Osmosis is different from diffusion in that whereas osmosis occurs only through a semipermeable (selectively permeable) membrane, diffusion can occur in any medium whether a semipermeable or not.

Explanation: Osmosis is the movement of solvent molecules from a dilute solution to a more concentrated solution through a semi permeable membrane, that is from an area of high solvent concentration to an area of low solvent concentration through a semi permeable membrane.

Diffusion is the movement of substances from an area of higher concentration to a region of lower concentration.

Osmosis occurs only in a semi permeable membrane while diffusion occurs in any medium.

Both osmosis and diffusion are examples of passive transport process and both aim at achieving equal concentration between two solutions.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
