    The tadpole question? It seems loads more obvious now but in the exam I had no idea and started talking about the fact it had eyes and I just feel so stupid :s ugh

    At least I managed to finish the paper (just) and the rest of it wasn't bad at all! (although no kidney/heart transplant stuff :c) The six marker was a gift!

    I hope everyone else feels good about it! Good luck for Chemistry and Physics next week!
    I too really messed up that tadpole question, I started talking about alveoli and haemoglobin and oxyhaemoglobin

    What do you think you have to get out of 60 to get 90 UMS?

    was the very last question asking us to talk about how glucagon was secreted by the pancreas and taken in by the liver to produce glucose from glycogen and then put into the blood?

    I don't think i've ever been this stretched for time. I was hadn't even started the last question when the invidulator said "Pens down." However, I was able to write in 2 or 3 points before they collected my paper - something about Glucagon turning glycogen (stored glucose) into glucose as the blood sugar level was too low.

    However, question 7 (both parts)- I wasn't able to read the question, just wrote something related to the graph.
    Is that right?^ anyone ??
    I sneaked rushed writing in at the end too. It felt so rushed. For one of the very first questions on the heart it asked you to suggest treatment to remove the clogged up veins. I didn't even know what the problem with the heart was called yet alone a solution. I said a heart transplant :P Probably a bit extreme.

    As for the last question I can't really remember what it was.

    in the last question, the concentration of glucose being delivered to the heart was increased, it didn't have anything to do with glucagon

    For the first part of the tadpole question did you put oxygen?
    Yeah, I I did. I do you know if it's right?

    Yes it has because the glucagon made in the pancreas will make the glycogen break down to glucose in the liver. The glucose is then released into your blood causing a higher concentration of glucose.

    It isn't 90%, it's 90 UMS
    I have no idea what UMS is. How many UMS is each paper out of?

    Um. Not quite. It's 90% in terms of UMS marks. Full GCSE constitutes to 400 UMS in total. To get an A*, you need 90%. Which is 360 UMS marks in total. So I guess you could say that each paper needs 90 UMS... hehe... Although you'll just need to add or minus the differences if you get higher or lower than 90 UMS per part.

    I messed up on the humidity/marathon runner question - i said as it is humid the blood gets hots and so it detected by the thermoregulatory centre, it then recalls the temperature but can't cool the person down to the humidity. - what on EARTH is WRONG with me!!!!!
