    Outline the causes of global warming — including the role of greenhouse gases (carbon dioxide and methane, CH4) in the greenhouse effect.

    Describe the effects of global warming (rising temperature, changing rainfall patterns and seasonal cycles) on plants and animals (distribution of species, development and life cycles).

    Explain the effect of increasing temperature on the rate of enzyme activity in plants, animals and micro-organisms.


    Describe how to investigate the effects of temperature on the development of organisms (eg seedling growth rate, brine shrimp hatch rates).

    Analyse and interpret different types of evidence for global warming and its causes (including records of carbon dioxide levels, temperature records, pollen in peat bogs and dendrochronology) recognising correlations and causal relationships.

    Describe that data can be extrapolated to make predictions, that these are used in models of future global warming, and that these models have limitations.

    Discuss the way in which scientific conclusions about controversial issues, such as what actions should be taken to reduce global warming or the degree to which humans are affecting global warming, can sometimes depend on who is reaching the conclusions.

    Thats all we need to know about global warming
    Does anyone know the answers to any of this???

    I dont know anything bout the global warming sectionnn!!! :confused:

    Completely agree with you. I get straight A's in all my other subjects but when it comes to biology im permanently stuck on a C (if I'm lucky!!) and the thing is I feel like I genuinely understand everything in the book but when it comes to exams the way the questions are written are so annoying! it takes ages to work out what they're actually asking, loads of them are maths questions and data interpretation (I don't do maths!!) and personally I think they don't give us enough time to complete the paper... If we were given extra time I know I could do better.
    what grades have you been getting in bio?

    It annoys me when maths questions come up or things related to chemistry, its not very fair on people that do neither of these a levels.
    Biology, when you the 1st question is a ***** or stress you out at the beginning like the JAN 2011 paper, it completely knocks you down cause ur mind think the other question would be exactly the same, and i hate 'SUGGEST' questions with a passion.

    Is anyone else absolutely ****ting themselves for this exam?!
    I've revised everything for topic 5/6, I know the core practicals and I've completed and marked all the past papers available (3 I think) and I still feel like I know nothing and feel hugely unprepared! the January exam has definitely knocked my confidence (I got a D) and just the fact that I know so much is relying on this exam to get into uni arghhh!! anyone else feeling the same?

    also does anyone else hate all the ecology stuff? I find that I only really understand and am interested in the human biology stuff like the immune system, but all the crap about succession and global warming is just soooo boring!

    what is everyone doing in terms of last minute revision?
    OMG sameeeeeee! :eek:

    I havent done any core practical stuff cos our teacher hasnt given us anyyything due to our second teacher randomnly leaving half way thru the year so she had to take on double the load in less time...
    and i havent done any past papers cos still feel i know nufinnnn in the content...
    but planning on doin all past papers later tonight/tmrww all day..

    yehh i need an A overall for A level in biology, i already got 2 B's in AS..but this is toughh!
    and yesss i hateeeee ecology stuff and the global warming stuff is boring.. ive only jus come to terms wid tryna read thru succession which wernt too bad...
    but yeh unit 5 seems soo much more interestin!!

    in terms of last min revision im firstly like :eek: :confused:
    and secondly jus like reading over notes...
    gna do past papers tmrw i guess :confused::confused::confused:

    They are a form of carbohydrate but not exactly, STARCH ARE CARBOHYDRATE CONVERTED INTO POLYSACCAHRIDE FOR ENERGE STORAGE. remember amylopectin and amylose? Branched and Unbranched chains?

    Isn't starch a polysaccharide anyway by definition?

    And the mark scheme said starch / sugar / eq

    So wouldn't carbohydrate be counted in the eq?

    I feel EXACTLY the same as you, Im relying on this exam to go to uni next year! I need a B minimum! and i also feel as i know nothing eventough ive done all the papers lots of times! i hope monday´s exam is a nice one.

    MS:
    - idea of carbon fixation produces {GP / eq}
    - (product) is converted to {starch / sugar /
    eq}'', which I assume the product is either GALP or glucose.

    Really the product of photosynthesis is glucose, which is then used to synthesise various things.

    The MS for Jan 11 was a weird one in general. I just did and got 66/90, and ended up getting 4/5, 2/3 on most questions. And the points which I missed, I would never have got them if I kept going on and on either. Maybe it is just me

    What I Have Noticed, State the Bleeding obvious in your answer, even if it looks like you would b repeating questions, some of them answer DO get you marks. I have met a lot of question like that, i would never have thought have to put it in cause its stupid and they are actually in the mark scheme
