A sample of red blood cells are placed in an isotonic solution and viewed under a microscope.
Then, sugar is added to the solution to create a hypertonic solution. The sample is then looked at under a microscope again.
What happened to the red blood cells after the sugar was added to the solution?
The water came out of the cells

What is the fluid mosaic model and what does it mean?
Fluid- moves around
mosaic- many parts
The cell membrane is fluid and flexible and made out of lipids, carbs and proteins.

How will the molecules move to reach equilibrium?
Molecule C will move across the membrane to reach equilibrium but Molecule D can not move across the membrane.
