1. in diagram 2, which term describes the solution outside of the cell? * 1 point

hypertonic
hypotonic
isotonic

Explanation:

For question 38:

• Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration).
• In diagram 2, the concentration of solute and water is the same inside and outside the cell. So, there is no net movement of water.

For question 39:

• A hypertonic solution has a higher solute concentration than the inside of the cell. A hypotonic solution has a lower solute concentration. An isotonic solution has the same solute concentration as the inside of the cell.
• Since the solute concentration is the same outside and inside the cell in diagram 2, the outside solution is isotonic.

Answer:

1. The cell will stay the same size
2. Isotonic
