    Look on page 6 there's loads of good responses.



    Exactly what I said.

    I was unsure whether to mention about capillaries and veins though?
    On top of the stuff you guys have mentioned, I went as far as talking about SAN, AVN, Purkinje Fibres, Atrial and ventricular systoles, capillaries over alveoli and stuff. Would I get marked down?

    Hi what do you think of this paper?
    I find this paper ok. I dont understand what is temporary mounts but now i do:ahhhhh:
    I put sellotape on slide.

    Unofficial Mark scheme(please QUOTE ME IN and help me out so everyone can see this on first page thanks I forgot some questions)


    Evolutionary history/relationship [1 mark]

    Species of similar characteristics that produce fertile offspring [2 marks]
    Notice if you put 'produce fertile offspring' = 2 marks

    Phylum, Class and Genus [1 mark]

    Two circles -1 for each genus then 1 circle inside each of those for the species [2 marks]

    ?????? [2 marks]

    About vigorous exercise -
    More blood to muscles for respiration thus release more energy for muscle contractions.
    Less blood glucose goes to small intestine [3 marks]

    many different cells for different functions in leaf -
    Organ [1 mark]

    56% [1 mark]

    Use scale bar as shown - 1.6 cm = 50 micrometers so whole length is 6.4cm/1.6 = 4 then x 50
    200 micrometers [2 marks]

    Some cells were undergoing DNA replication whilst other cells had finished/not started it [1 mark]

    Describe the patterns of blood circulation from Kidney blood transported and then return back to Kidney.
    Blood leaves kidney via renal vein; [6 marks]
    To vena cava - Blood in vena cave goes to right atrium;
    Right atrium to right ventricle. Then pulmonary artery to lungs to be oxygenated;
    Then pulmonary vein to left atrium then to left ventricle;
    Then left ventricle pumps it down the aorta;
    Renal artery goes back to the kidney;
    Renal vein -> vena cava -> pulmonary artery -> pulmonary vein -> Aorta -> Renal artery

    The mesenteric advantage 3marker i put
    - Less blood flow to small intestine as not actively absorbing glucose etc
    - More blood avalable to flow elsewhere to the body
    - More blood able to carry o2 to respiring tissues/cells
    -More respiration/more energy able to be generate for cells during intense exercise

    Thing is. I wish I could say " I messed up, i didn't revise/ it was hard" but i tried my best ... It wasn't hard, it was just stupid. My teachers agree too, AQA is just an horrible exam board for A level BIOLOGY.
    That's why my head of Biology changed our school's Biology exam board for A-levels. Yep, after our year.

    As long as your biology is fine, you will not be marked down.

    I did 4 and labelled each with the specific genus name and species name

    The problem with that, and I might be wrong, is that you're saying one genus is in another genus, and that another species is in another species.

    If they said "define tissue", i wouldve said something like "group of similar cells working together"

    Which is why I wrote tissue when they phrased the question something like "a leaf is made up of a group of similar cells, what's this called"

    Cos like the definition of an organ is "group of similar tissues", it's so annoying that was such a mean question hahah

    They said different cells not similar cells so I put organ. I may be wrong

    i rwote tissue and replaced it with organ because it mentioned that they carried out different functions or something.

    What were the two hypotheses? My brain was mush at that point, i was day dreaming about dinner... lol

    i Worte ther is no significant difference between the number of chickens with resistance bacteria and the number of what ever the other animal was

    and there is no significant difference between the number of chicken farmers with resistanct bacteria and the number of chicken farmers
