If a scientist drops an animal cell into a solution that contains 10 times more salt than is found inside the cell, which of the following will happen? Hint: drawing a picture may help you. A) The cell will burst since the solution is hypertonic B) The cell will shrink since the solution is hypotonic. C) The cell will burst since the solution is hypotonic. D) The cell will shrink since the solution is hypertonic. E) The cell will not change in size since the solution is isotonic.
