water as seen with a compound light microscope.Which diagram below
best represents the appearance of that cell after it has been
placed in a 15% salt solutionfor two minutes? This is a high salt
concentration solution,therefore a hypertonic solution. Water will
move OUT of the cell, causing it to shrink within its plasma
