Our eyes sting when we get very salty water (such as seawater) in them. Tears also contain salt, but they do not sting our eyes the way seawater does. Using the following terms appropriately, answer the following question. Terms to use: Cells    Osmosis Hypertonic/Isotonic/Hypotonic (Note: you only need to use TWO of these. One can go unused!) Solutes Question: Why does seawater sting our eyes, while our own tears usually do not? (You should address BOTH parts of the question. This can be done in 2-4 sentences.)
