Nemo and other ocean dwelling fish cannot survive in freshwater because......

• freshwater is hypertonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypotonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypertonic to Nemo's cells and will result in water entering them causing the cells to swell and burst

• freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst

In an isotonic solution which way will the water flow

• it will not flow at all

• it will flow into the cell

• it will flow both ways at equal rates

• out of the cell

What would happen to a cell placed in a hypertonic solution

• The cell would shrink

• The cell would expand and possibly burst

• The cell would remain the same

• The cell would dance and do the Nay Nay!
