Answer:
c. Osmosis is the diffusion of water molecules across a selectively permeable membrane.
Explanation:
Osmosis is the passive transport of water molecules from the region of their higher concentration to that of lower concentration through a semi-permeable membrane. Osmosis does not include the movement of solutes. When two solutions with different concentrations of solutes are separated by a semi-permeable membrane, water moves through the membrane from a hypotonic solution to the hypertonic solution until equilibrium is obtained. This process is called osmosis.
Two causes of the ocean can be floods or tsunamis. Also technically hurricanes are a cause of the ocean as well as precipitation, such as thunderstorms or snow.
