1 point
A The organism’s cell will absorb too much water through osmosis.
B The organism’s cell will release too many hydrogen ions through diffusion.
C The organism’s cell will release too much water through facilitated diffusion.
D The organism’s cell will absorb too many sodium ions through osmosis

Answer 1

C The organism’s cell will release too much water through facilitated diffusion.

Answer 2

The answer is actual A. This is a hypotonic/hypertonic question. Because its a saltwater cell in freshwater, lets look the definition of a hypotonic solution. "The solution (freshwater in this case) has a lower solute (salt) concentration than the cell (the saltwater organism) so water MOVES INTO THE CELL by osmosis, causing it to swell if plant and swell then burst if animal"
