a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membran.
The enzyme pepsin functions with a very low pH of around 2. It is found in the stomach, with the acidity coming from the hydrochloric acid present there. it breaks proteins into amino acids.
When water molecules
diffuse through a cell membrane this process is called the osmosis. Water
molecules are extremely small and because of this they can slip freely through
the gaps between the phospholipids in the cell membrane. And as a result, water
molecules can constantly move back and forth though the cell <span>
membrane. This movement of water has a very important
function and that is it enables cells to absorb water. </span>
Now for a movement of
water molecules to happen, there should be a concentration gradient in the surrounding.
That is, the amount of water in one side must be different on the other side.
<span>For water to diffuse
INTO the cell, the amount of water outside the cell membrane should be larger
than the amount of water inside the side.</span>
Answer:
Plants absorb nutrients and water and and is anchored through their roots
Explanation:
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
