The Veins carry blood to the heart
Answer:
a. Nothing happens because the two solutions are isotonic to one another.
Explanation:
Two solutions of the same molarity are separated from each other by a membrane that allows water molecules but not the glucose or sucrose to move across it. Movement of water across the selectively permeable membrane occurs only when two solutions have different concentrations of solutes. In that case, water moves from a hypotonic solution towards a hypertonic solution. Since both sucrose and glucose solutions have the same tonicity, there would not be any change in the solution.
If a scientist observes an enzyme polypeptide chain arranged in spiral turns that rise upward and are held in place by hydrogen bonds he/she is looking at a tertiary structural arrangement.
The flexible lipid bilayer that surrounds the cell and acts as a selectively permeable barrier that regulates what enters into and what exits out of the cell would be the cell or plasma membrane.
