Which of the following is true about the relationship between Cell A (dimensions .5x.5x.5) and Cell B (dimensions 1x1x1?
Cell A has a higher surface area to volume than Cell B and is therefore better able to transport materials in and out of the cell.
Cell B has a higher surface area to volume than Cell A and is therefore better able to transport materials in and out of the cell.
Cell A has a lower surface area to volume than Cell B and is therefore better able to transport materials in and out of the cell.
Cell B has a lower surface area to volume than Cell A and is therefore better able to transport materials in and out of the cell.

The shows 3 dialysis bags filled with water based solutions with different concentrations of sucrose, or sugar. The bags are placed in a solution that’s is 1% sucrose.
Which of the solutions is hypertonic compared to the others?
The beaker solution
Bag B
Bag C
Bag D
The shows 3 dialysis bags filled with water based solutions with different concentrations of sucrose, or sugar. The bags are placed in a solution that’s is 1% sucrose.
If the mass of each bag isn’t taken before and after soaking in the 1% solution, which is most likely to occur?
All the bags will lose equal amounts of mass as sucrose moves from areas of higher concentration in the bags to areas of lower concentration in the beaker
All the bags will gain mass as water moves from hypotonic areas in the beaker to hypertonic area in the bag. Bag D will gain the most mass.
All the bags will gain mass as water moves from hypertonic areas in the beaker to hypotonic area in the bag. Bag D will gain the most mass.
All the bags will gain mass as water moves from hypotonic areas in the beaker to hypertonic area in the bag. Bag B will gain the most mass.
The figure above depicts a U shaped Ruben witch 2 sides depressed by a semi permeable membrane. The tube contains water with sucrose on both sides. The dots are the sucrose.
Which is most likely to occur after the solutions are in the tube for 20 minutes?
The volume of side A decreased and sucrose moved from A to B
The volume of B decreased as water moves from hypertonic B to hypotonic A
The volume of B decreased as sucrose moved from B to A
The volume of A increased as water moves from hypotonic B to hypertonic A
A cylindrical potato is placed into water. The mass isn’t taken before and after soaking. The mass increases by 1.5 grams. Which isn’t most likely to happen if you cut it into 5 pieces and put them into the water for an equal amount of time?
The gain less than the total mass of the uncut potato because the uncut has a higher surface area to volume ration
The cut potato gains more mass because the cut potato pieces have a higher surface area to volume ratio
The potatoes gain equal amount whether cut or uncut
The potatoes will lose equal amounts regardless
