Which term describes the transport that occurs when molecules are carried along with a solvent through a semipermeable membrane?

The term that accurately describes the transport occurring when molecules are carried along with a solvent through a semipermeable membrane is convection. In this process, not only do the solvent molecules move, but they also carry solute molecules along with them, leading to a more comprehensive movement that can include larger particles. This is particularly relevant in situations like hemodialysis, where a mixture of substances is transported across membranes because of the flow of the solvent.

In contrast, diffusion refers specifically to the movement of solute molecules from an area of higher concentration to an area of lower concentration, without the displacement of solvent. Osmosis is more focused on the movement of water through a semipermeable membrane toward a higher solute concentration. Filtration involves the movement of fluid and solutes driven by pressure, which is different from the process described in the question. Thus, convection is the correct answer as it encompasses the transport of molecules together with the solvent through a semipermeable membrane.
