To provide accurate answers to your questions, I need to know the context in which the cell is placed (for instance, is it in a hypertonic, hypotonic, or isotonic solution?). However, I can provide some general principles regarding solute and solvent movement in different scenarios:

  1. Which direction will the solute move?
    This depends on the concentration gradient:

    • If the surrounding solution has a higher concentration of solute than the cell (hypertonic environment), then the solute may move out of the cell (b).
    • If the surrounding solution has a lower concentration of solute than the cell (hypotonic environment), the solute may move into the cell (a).
    • If concentrations are equal (isotonic environment), the solute will not move (c).

  2. Which direction will the solvent move?
    The solvent (often water) will move according to the concentration gradient of the solute:

    • In a hypertonic environment, solvent will move out of the cell (b).
    • In a hypotonic environment, solvent will move into the cell (a).
    • In an isotonic environment, the solvent will not move (c).

  3. The cell contained 45% glucose. What is the percentage of solute and solvent?

    • The solute (glucose) percentage is 45%.
    • The solvent (water) percentage in the cell can be calculated by taking 100% and subtracting the solute percentage:
      \[ 100% - 45% = 55% \]
      Thus, the percentage of solute is 45%, and the percentage of solvent is 55%.

  4. After the cell is placed into the beaker, which of the following changes would occur?
    This again depends on the environment:

    • If the beaker solution is hypertonic (higher concentration of solute than the cell), the cell will shrink as water leaves the cell.
    • If the beaker solution is hypotonic (lower concentration of solute than the cell), the cell will swell as water enters the cell.
    • If the beaker solution is isotonic (equal concentration), there will be no net change in the size of the cell.

To give you more precise answers, please provide the environment of the beaker solution relative to the cell's solute concentration.
