    Here's a wild stab in the dark...

    1. Fossils and Evolution (Came up last year but never before)
    2. Distribution of Organisms (never seen much on it)
    3. Stem Cells

    They tested us on really obscure topics in the unit 1 science exams, better not do the same again :/

    I'm thinking stem cells, cloning or GM might come up because they've been big topics in the media this year! Also the circulatory system as I haven't seen that much in past papers and probably a bit about growth and plants which seem to be a common theme. good luck for tomorrow guys!

    I really hope stuff about mitosis and meiosis, protein synthesis or cloning comes up..
    I'm better at that kind of stuff. I hope the paper won't be too difficult, I sat a past paper for B2 where I got an A but then another paper I couldn't even manage a B!

    That was a tricky one. I basically put that as the muscles of the small intestine contract, the fibrous material that isn't digested also moves in the same direction which helps push the food down.

    It was easy apart from I got the obvious quadrat question wrong! Oh well, it's only one mark.

    I put that the walls of their intestine wouldn't be as muscular, and so won't push food though as effectively.

    I said some bull**** about how muscle contraction waves (peristalsis) did not happen as much if less fibre was consumed meaning that peristalsis wouldn't occur as well in the small intestine due to not being used to it :/

    I got -4.86%, forgot which one it was. To get the answer, divide the end result by the primary mass, the answer was like 0.9514. Take the number away from 1 and convert to a percentage. Was obviously a minus percentage because the mass decreased.
