Question

Quizplus · Accepted Answer

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, which is the case with the nutrients absorbed by the trophoblast, moving towards the inner cell mass. Osmosis is the movement of water molecules across a selectively permeable membrane, and peristalsis and ciliary action involve the movement of muscles and cilia, respectively, which are not applicable in this scenario. Convection refers to the movement of fluids, which is also not applicable here.
