When is osmosis used by cells to move water across a selectively permeable
membrane?

A. Osmosis is used by cells when large molecules pass freely across the selectively permeable membrane.

B. Osmosis is used by cells to create equilibrium when large molecules can't pass through the membrane.

C. Osmosis is constantly in process inside of a cell, regardless of equilibrum.

B.

Explanation:

Osmosis moves water from the part of the membrane with less solutes to the part with more solutes. This will continue until the cell or whatever it is reaches equilibrium.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
