(2: DOK 2) Explain what happens to a snail when salt is poured on it and how this reaction relates to tonicity for cells.
O a) The addition of salt causes water to leave the snail by active transport, just as a
blood cell shrinks due to active transport when placed in a high salt concentration.
b)
The addition of salt causes water to leave the snail by osmosis, just as a blood cell
would shrink by the diffusion of water out of the cell, if it were placed in a high salt
concentration solution.
c) The addition of salt causes water to enter the snail by diffusion. just as a blood cell
swells when it is placed in a high salt concentration solution,
d) The addition of salt causes water to enter the snail by diffusion, just as a blood cell
swells when it is placed in a high salt concentration solution.
