Answer:

C. Osmosis

Explanation:

Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.

Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.

Osmosis is controlled to a large extent by concentration gradient.

Diffusion on the otherhand is the movement of molecules of a substance from one position to another.

Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.

How are the hydrogen bonds in water responsible for many of the molecules unique characteristics?
DiKsa [7]

Hydrogen bonds exhibit the stronger intermolecular force, and water is a polar molecule, so the hydrogen bonding create strong forces which take more energy to break (causing the surface tension of water), and due to the polarity water molecules “stick” to one another which causes the edges to rise up in a tube, forming a meniscus
