a cell with a 5% salt solution is placed into a beaker with a 10% salt solution. what is the beaker solution considered relative to the cell, and what will happen to the cell?
hypotonic-cell will swell
isotonic-cell stays the same
hyportonic-cell will swell
hypertonic-cell will shrink

Explanation:

Osmosis is defined as the diffusion of water across a selectively permeable membrane. For the cell - solution problem, a hypertonic solution has a higher solute concentration than the cell. Water will move out of the cell (osmosis) to balance the concentration gradient.

Answer:

For the first question: water.
For the second question: hypertonic - cell will shrink.
