## Step 1<br />This question is about the biological concept of osmosis. Osmosis is the process where water molecules move from an area of lower solute concentration to an area of higher solute concentration across a semi-permeable membrane. <br /><br />## Step 2<br />In this case, the freshwater protozoan is placed in a highly concentrated saltwater solution. The salt concentration in the saltwater solution is higher than the water concentration in the protozoan cells. <br /><br />## Step 3<br />According to the principle of osmosis, water molecules will move from the protozoan cells (where the water concentration is higher) to the saltwater solution (where the water concentration is lower). <br /><br />## Step 4<br />As water leaves the protozoan cells, the cells will shrink due to the loss of water. This process will continue until the concentration of solutes is equal on both sides of the cell membrane, which is the point of equilibrium.
