    there's a website called exam.net I believe that is dedicated to Biology. I know that some pages however can only be viewed of your school has registered. Alternatively try the BBC for their GCSE stuff.

    I think, but am not entirely sure (as depends whether tonic refers to water or sugar/salt) that the words mean:

    HYPERTONIC - Higfher level of water than normal

    HYPOTONIC - Lower level of water than normal

    ISOTONIC - Remaining at a constant water concentration
