The image shows a beaker of a sucrose solution (sucrose is represented by the blue circles). The beaker is divided into two sections of equal volume by a membrane which is permeable to sucrose.
Which of the following scenarios is most likely to occur?
There will be a net movement of the sucrose molecules from the top of the box to bottom of the box.
There will be a net movement of sucrose molecules from left to right.
There will be no net movement of sucrose molecules.
There will be a net movement of sucrose molecules from right to left.

Inside one dialysis bag, labeled A, is a 50% glucose solution. Inside another dialysis bag, labeled B, is a 20% glucose solution. Both bags are placed into beakers containing water from a fresh water pond.
Which is the correct outcome?
Bag A will gain weight.
Bag B will gain weight.
Both bags will gain weight.
Both bags will remain the same.
Both bags will lose weight.
Inside one dialysis bag, labeled A, is a 50% glucose solution. Inside another dialysis bag, labeled B, is a 20% glucose solution. Both bags are placed into beakers containing a 30% sucrose solution.
Which is the correct outcome?
Bag A will lose weight and bag B will gain weight.
Bag A will gain weight and bag B will lose weight.
Both bags will lose weight.
Both bags will gain weight.
Choose all answers that are true. (There are more than one!)
The concentration of solute in the solution is lower than the concentration inside the cell.
Water will leave the cell causing it to shrink.
Water will enter the cell by osmosis causing it to swell.
The concentration of solute in the solution is higher than the concentration inside the cell.
The cell is in a hypotonic solution.
