Answer:
Cellular energy
Explanation:
Osmosis is the movement of water from a less concentrated to more concentrated solution across a semi-permeable membrane. Cellular energy is not required in osmosis because it is a passive process. Osmosis is technically more or less the selective diffusion of water molecules across a membrane that selectively locks out other larger molecule like ions. Water will, therefore, move from the solution where there are more water molecules to the solution with fewer water molecules.
According to the research, the linear vein is a tributary blood vessel of the hepatic portal vein.
<h3>What is the hepatic portal vein?</h3>
