    your teachers told you your cwk mark?? my teachers refused to tell us as he said it can be changed a lot when moderated
    Yeah our head of biology moderated our whole year's before she sent them off, and mine wasn't moderated externally and stayed the same at 40

    If you marks stays the same or not is not dependent on whether it's included in the moderator's sample - it stays the same if the teacher's marking is correct (as represented by the sample).

    My teacher said my c/w was easily able to gain 40 marks but she gave my 39 because the examiners may be too harsh n bring it down- her words, not mine

    Admittedly I put capsule too, it was incredibly unlcear. Could have gone either way but hey ho.

    Anyone put Eucaryota as C and Archea as B in the classification Carl Woese question?
    I did and it actually makes sense eukaryota can have chlorophyll

    Umm...i don't think the slime capsule is right..that's cuz there was no LABEL for the cell wall..i'm super sure about that..so it's gotta be cell wall..and a the question said that the diagram showed a TYPICAL prokaryotic cell..and typical cells dont have slime capsules, slime capsules are only SOMETIMES present..so yeh
    I think edexcel will be generous and put both capsule and cell wall

    "and [my mark] stayed the same at 40 "
    Don't know why you have to be so negative to everybody

    LOL, it's like the 100th time you've said you've got 40, we get it already, no one actually cares.

    And I wasn't negative. Your statement may have worried people who were under moderation and think that they're mark wasn't safe, as if in the sample - you will get marked down, when everyone is equally affected by moderation.

    I quote; 'mine wasn't moderated externally and stayed the same at 40'

    Clearly this implies: being in the moderation sample --> mark would have gone down. If anything I reassured people against your false suggestion

    You're the hardest person I know because of your use of size 7 font.

    stop trying to put everybody down, just because you got the easiest question in the paper about the cell wall label wrong... LOL

    clearly because you're too good for us all? who do you think you are?
    and I've been scrolling through this discussion thread, and you spelt "goodbye" as "good bye". so if you're gonna be a grammar nazi, get yourself to a job centre.

    I think that's completely wrong.
    -make agar solution
    -pipette out bacterial broth
    -open lid just enough to allow entry of bacteria
    -use aseptic conditions
    No!! when adding bacteria

    -lawn the bacteria
    - evenly
    - using aseptic conditions (however the next question asked about the aseptic conditions)

    My teacher always says: when adding bacteria you have to lawn!!

    its so irritating to come to the Biology thread and see people arguing about petty 1 mark questions. can someone do what they did on the Chemistry Unit 2 thread. write all the questions that came up and the marks allocated to everyone can try and guess what they got =) thanks

    It's shocking how you'd even show your face after promising everyone to give full sets of 'FULL 120/120 UMS' notes 2 days before the exam and not even apologize about lieing. Just saying.

    Erm, firstly, totipotent stem cells have all their genes switched on, ready to make any type of cell, this is GCSE knowledge. If one single gene is deactivated, that means mrna can't be transcribed from it, a protein can't be made, and so the cell will not be modified in a specific way, and that's one less differentiated cell.

    All genes must be switched on ready to make any type of cell. If you read the revision guide, active gene does NOT equal transcription, under the correct stimulus transcription will occur.

    Secondly, LOL that wasn't a cell wall, click on this link and this link, and read out to me what it says for the final outside layer. Thanks. I don't know what disapointment you're talking about.
    Okay yes about the totipotent thing you're right I understood the question wrong, I was in hurry I don't think that I read the question right but about the cell wall thing I believe that I am right..see speaking about the revision guide if you read it well you'd have noticed that capsule is "sometimes present" in the prokaryotic cell that's why I don't think that capsule is the answer required open your revision guide and take a look at it
    and by the way I think you got me wrong when I mentioned the disappointment!!!....I really hope everyone best of luck and for you too, and you never know hopefully they'll consider both cell wall and capsule correct answers...that's a little bit dreamy but you never now ;-)
