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

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"

Answer 2

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