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
