    I think I miss interpreted the question I thought it meant like growth etc in humans and other organisms!!! So yours would all be rigjt
    I think yours will be right too! I figure as long as you talked about growth and why it was important it will be ok! Don't worry most marks for science content anyways, loads of people I talked to did not enjoy the paper...

    Everyone did the reserve paper due to the possibility of the other being leaked and also it isn't fair for some to do one and other to do another.
    Some people didn't get the reserve paper on time (just like with the psychology paper yesterday); mainly those oversea.

    Ratios have to be something; 1 as you have to divide by the smaller number not the larger one

    I did 10 a for the essay,
    I talked about:
    - Blood glucose concentration
    -Immunity & pathogens
    - haemoglobin
    -heart rate response to acidity in blood

    It's mostly internal changes, would I lose marks for not mentioning a lot of external changes? :/

    I talked about rate of photosynthesis being controlled in agriculture (optimum conditions) to get the best yield, linked to the second paragraph by talking about yield again but by using recombinant DNA for disease resistance, then controlling disease in humans using siRNA and finally contraceptive hormones like the oestrogen-progesterone pill and the progesterone implant and the reasons people want to delay having a baby. I wanted to talk about selective breeding but i felt like i would be jumping from topic to topic
    Ah brill thanks! I wrote about photosynthesis in plan but didnt get round to it... feel we've all gone roughly ssame way with it... feeling a bit better now... thanks!

    I did the first essay; internal/external environments. One of the topics I wrote is muscle contraction, so sliding filament theory, and how a stimuli causes a muscle to move etc. Would that be relevant? I haven't seen anybody that included it.

    More testosterone inhibits pituitary gland so no FSH/LH therefore no/less sperm or testosterone

    Did anyone here use extra paper?
    Did you put the number and the letter into the left hand column ( e.g. 9e) or just the number (09)?

    questionaire question was a bit dodgy
    Ahh yes. I said the people surveyed might not be representative of the population? and that people might lie cause they could be ashamed to admit that their parents smoke, lol.

    Ye i only lost marks on that muscle one and antibody one and maybe one transcription question. So maybe 8-9 in the first section and like 7 marks on the essay . So i think am looking and atleast 82-80..
    Assuming i lost all the marks and got no other random marks for that question.

    I wrote about photosynthesis and respiration for 10.a. in terms of changing light intensity causing increased rate of photosynthesis and more ATP needed for movement for respiration. Is this relevant?
    I put that

    Will I lose any marks for 1:2.27 for the ratio?
    Also how about these essay topics for b:
    Intensive farming of animals
    Growing crops in optimum conditions (all for growing population)
    Finding genetic diseases using dna probes
    Genetic counselling to help prevent incidence of genetic diseases
    Growing fungus that produces antibiotics for prevention of pathogenic diseases
    Genetically modifying crops
    - I wrote about five pages on all these topics
