    I put Vein, Capillaries, Artery
    Ohh it was Artery, Capillary, Vein. The arrows were indicating the blood flow so that's how I knew.

    That's exactly what I got
    Same, I thought after hearing what people have being saying that it was the other round when I was posting, but thinking now, that's what I put.

    What did everyone put for the runner one?

    I put he couldn't sweat because it was against the concentration gradient etc

    Yes, but yours was right after you changed it.
    I'm sure you've done fine! Don't worry about it, now just focus on the other exams

    I put that there was no evaporation in the humid environment and so he overheated!

    Im sorry, I didn't take the B2 exam today but I was told by some friends that took it that it was relatively hard. Your best bet is to visit this thread and ask someone there as they probably have a better idea than me

    I just ran out of ideas about the runner one. Though I did talk a little bit about sweat and evaporation.

    What did you get for the transpiration stream and active transport and osmosis plants question??

    I'm so glad there was nothing on biogas! I couldn't for the life of me get the hang of that stuff!

    Capillaries are only one cell thick though? I don't think you can have capillary stents.
    That's what I mean! On the diagram it showed that the vessel was one cell thick that's why I put capillary... I'm pretty sure you were right though and I was wrong, only one mark though

    Transpiration Stream: Water drawn from roots up stem in Xylem to leaves because of evaporation.

    Other one: More concentrated in roots, active transport needed etc.
