In an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution.
(b) Identify the osmolarity of the apple.
Assume a cell has an osmolarity of 10 mM. What will happen to that cell (swell, shrink, or stay the same) if it is placed in a solution of:
a) 5 mM glucose
b) 10 mM glucose
c) 10 mM NaCl

- Soft contact lenses are made from hydrogels, which make them soft and flexible. It is important to clean them daily using a sterile, isotonic cleaning solution. The concentration of solutes in the cleaning solution is the same as the concentration of the hydrogel in the contact lens. What would happen if instead of an isotonic cleaning solution, soft contact lenses are cleaned with water? (A) The soft contact lenses will shrink because it will remove too much water by osmosis. B The soft contact lenses will shrink because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is removed by osmosis.arrow_forwardAn osmotic semipermeable membrane that allows only water to pass separates two compartments, A and B.

What is the osmolarity of these solutions? Please show your work. b) If you soak an animal cell that is permeable to both water and glucose in either 5.5% glucose or 0.9% NaCl (both isosmotic solutions), the cell exposed to 5.5% glucose will gain water, while the cell exposed to 0.9% NaCl will not gain water. Predict why this is the case.arrow_forwardIn osmosis, water flows from hypertonic/hypotonic/isotonic solutions to hypertonic/hypotonic/isotonic solutions, until both solutions are hypertonic/hypotonic/isotonic.arrow_forward
