    I wrote that carbon monoxide would bind with the red blood cells, causing there to be less oxygen around the , so there would be difficulties in breathing.
    I did not talk about hemoglobin at all.

    Will i still get full marks?

    I wrote dendron
    I don't understand why it was a dendrite though (
    They wont accept dendron I'm positive unfortunately.
    Apparently dendron and dendrite is the same and you'll get a mark either way

    Who thought that the test today was easy. I think it was the easiest paper I have done I knew the answer to every single question and the six mark question was in a past paper (the regulation of blood glucose). What did you think of the test?
    is it possible for edexcel to remove questions on the b1 gcse paper e.g the cf infertility one

    If you mess up the names in the blood glucose concentration will you still get the marks
    no, that's what they're testing you on. you may get 1 or 2 -if you're lucky- depending on whether or not you showed an understanding of the process

    I think as long as you didn't say that the nicotine and tar was the reason they found exercise hard and couldn't breathe properly you should get the marks
    I said that by smoking their lungs become unhealthy, so they take less oxygen to muscles, meaning that the body has to work harder to get the amount of oxygen needed.
    I didnt say anything about carbon monoxide or haemoglobin though, would it still be right?

    i think you would need to say the red blood cells wont be able to give oxygen with the blood to respiring cells who need it during excersize

    I think the paper was so easy, i'm so happy! but i got stuck on th emutualism because i didnt thoroughly revise that. i put
    Oxpecker removes dead skin cells from other animals
    Cleaner fish remove dead skin cells from bigger fish e.g shark
    Chemosynthetic bacteria makes sulphide compounds for tube worms

    How many marks would this get me???
    I'm guessing about three - purely because i would think they would want you mention how the host benefits as well

    I got the process right, but mixed up the names of glucagon and glycagen. Roughly, how many marks will I get.
