    thats what i did! except with breathing rates. my unfit person had a higher rest breathing rate also

    I did 2 linear graphs with the unfit persons heart rate increasing quicker and the fitter persons heart rate increasing more steadily

    What did you guys put for the name given to the regions of plants which secrete growth regulators?

    The meristems

    Ugh.. talk about a poorly phrased question. Felt like they were asking for a certain species of plant.

    isn't it the zone of elongation? The meristem is the zone of reproduction, the zone of elongation is where auxins are secreted?

    Ah ****e, they're produced in the meristems, but secreted in the zone of elongation, isn't that it? Oh well, another 3 marks gone.

    Meristems are located in the zone of elongation and apricol bud. They produce and secrete the growth promoters.

    At this stage, I think the marking scheme will give marks for Meristems because technically it's right.

    9bv) After the plate was flooded with iodine the entire surface of the agar changed colour from brown-yellow to blue-black

    vi) The digestive enzymes in the beans had been denatured so digestion of the starch had not occurred, meaning that starch was still present in all of the agar which caused the colour change

    If you used skimmed milk/protein agar it'll be different, I presume you use biuret reagent and it changes from blue to purple

    The amount of time wasted studying for this horror of an exam for it not to even be counted is a bit sickening.

    My daughter spent most of her time on Biology last year, studied it to bits and got D1. Terrible waste of precious study hours too. She did very well in all other subjects, still can't understand it.

    Just because you spend time studying doesn't mean you are going to get good grades, you also need to have aptitude.

    If you didn't get the marks then you didn't have the right answers. All questions are based on the syllabus. Tricky questions are meant to challenge the good students while separating them from the weak students. You see this all the time in Mcqs. They will have enough easy questions for the students who want to pass and then the trickier questions will be answered correctly by the better students.

    You would be a fool to think that just because you studied you are guaranteed good results. Its application of information which matters, which is why the weaker students get caught out by curve balls.

    Set last year's wrong right and got my A2 up to an A1. Shame my C1 in maths disbars me from most science courses though:rolleyes:

    EDIT: EoghanIRL, there's no need to be so rude to the woman, she's just disappointed for her daughter. Even though I got an A1, I have to say the questions were funky as hell this year.

    I was the exact same.It was my worst result by far and the one I put most effort into weirdly enough. Who knows what more I could've got had I focused mostly on those six I counted

    I had pegged Biology as one of my worst subjects (that I was counting) ended up getting a B2 up from a D1 in the mock!
