If the contents of a cell have a solute concentration of 0.04 percent, which of these solutions would cause it to swell? 10–percent solute concentration 1–percent solute concentration 0.1–percent solute concentration 0.01–percent solute concentration

Osmosis is the natural phenomenon where molecules move from a region with a  lower concentration to a region with a higher concentration, relatively. IN this case, a solution that will cause a cell to swell is a solution with lower concentration. Hence, the answer would have to be 0.01 percent solute.
