When the water inside a living cell freezes, the ice crystals damage the cell. The wood frog is a unique creature that can survive being frozen. In extremely cold
conditions, the frogs liver produces large amounts of glucose (C6H12O6), which becomes concentrated in the frog's cells. How does the glucose help prevent ice
from forming in the frogs cells?
A)The added glucose dissociates and creates faster moving molecules.
B) The added glucose lowers the vapor pressure relative to the pure solvent.
C) The added glucose requires more energy which warms the frog
D)The added glucose lowers the freezing point of the solution within the frog's cells.
