    What topics do you guys think will come up in this exam? Is there some sort of pattern? It's such a massive unit, so imo luck plays a big part. People could do minimal revision but be fortunate enough to find themselves in a position where only stuff they learnt comes up, so they do well. Whereas those who did tons of revision spread evenly across the whole module, will be at a disadvantage.

    Personally, I hope it's heavy on Disease and Biological Molecules.

    The January module was quite heavy on biological molecules :/ but that doesn't mean we won't get some in this June's paper. I think it's going to be quite evenly spread, and there will be lots on evolution as opposed to maintaining biodiversity. For the disease part, they may have the worldwide importance of malaria etc. and how they are transported? There wasn't any enzyme or DNA replication in the January module either

    Quick question guys,

    On the adaptation section in the textbook, it uses the example of xerophytes for each type of adaptation.

    The spec doesn't say anything about knowing adaptations of xerophytes

    Do you guys reckon we need to know it?

    Yep we need to know specific adaptations, or at the very least examples of each type e.g. behavioural, physiological, biochemical etc

    The elastic fibres in their alveoli have become damaged and therefore they cannot recoil as effectively, leading to less exhalation.

    Adaptations - behavioural - leaves coil up when their is low humidity to prevent water loss via transpiration, biochemical - saprophytic organisms like fungi release extra cellular enzymes to digest food externally, physiological - ..... Not that sure...
