    Nope, 2*10^6 / 3*10^8 = 0.0066666666..., then you multiply that by 100% to get 0.6666666666...%

    They were being so cheeky with that, those images were different to the actual snails in the answer

    What points did you guys make for the 6 marker question. Completely wasn't expecting healthy diet question.
    Off the top of my head:

    Carbohydrates - Release energy for use in the body such as muscle contraction

    Proteins - Making new cells, repairing cells.

    Fats and Oils - Making cell membranes, insulator

    Water - Hydration

    Fibre - Keeping your gut healthy and helping food move through your small intenstine

    Vitamins - General healthy functioning and upkeep of your body

    It was the number who died divided by the number who suffered from malaria x 100 which gave me 0.(6 recurring). That's how I did it anyway.
