    Want bio p31 answers ? (ask here)

    Yeah, I agree, I just wrote respiration myself, so we may get 1 mark, or even the full too, they can be leniant.. Yeah, I'm aiming for an A* too, unfortunately, I have found a mistake with my table work (2 marks), and also with my uses or proteins (2 marks) other than that, my answers have...

    You may not get enough marks, you might get 2 or 3, as the stripes develop due to a mutation..

    The graph is plot with temperature change against different masses of zinc used.. So when it is powdered, the temperature rise will be greater.

    Okay, basically, you need to add water, as they are water soluble. Then you use a pestle and mortar to crush them.. Then you filter off the solid berry parts, leaving the berry colouring in solution. For part (b) You need to say that you would test it with an acid and a base, and then note that...

    CHEM P6

    Solvent would be alcohol as they are not water soluble.. A labelled diagram is the easiest path to 4 marks, just remember to not put the solvent level above the origin line. If you want to explain, just explain it step by step... Draw the origin line in pencil, place a spot on the line, dip the...

    Ahhhhh... It's so hot here.. ¬¬ Anyway enough random information, I have a question about what potassium iodide is used to test for :S.. With the volume of CO2, the final volume produced would be the same, the line would just be steeper.. With temperature on the y-axis, the rise will still be...

    Main points are: The chromatogram, the solvent used, the solvent level must not be above the origin line.. Make sure you are able to describe the methods of applying them too.

    Probability is a percentage or a decimal.. Percentage is accepted as a probability.. I do statistics at AS Maths level, so 25% is accepted..

    I wrote 25% because 1 was A, the other was B, the other was O, and the other was AB, so 1 in 4, 25%..

    Ahh, I love it when people say that :D Seems like I got them correct apart from D, which I see where you are saying about the floating, because the leaves were buoyant, which was an adaptation right?

    Ahh, sorry man, I didn't read the previous pages.. Thanks for the explanation of the salt anyway, incase it does come.. I hope it goes as well as Physics paper 6, and nowhere near as bad as biology paper 6.. Before the exams started I was more nervous about Bio than Chemistry, but now it's...

    Yey :D.. I wrote that the air space were for storing extra air, and the oxygen from photosynthesis.. Stomata and guard cell for letting CO2 in, and C was for Photosynthesis As well as A and B there was a labelling for the amniotic sac and fluid.. I could be wrong, so I don't want to argue as I...

    A wasn't the sac, as it was already labelled :S.. I think anyway..

    Thanks for clarification :D.. After losing stupid marks on that table and proteins was a real downer... Anyone remember the plant labels?

    Knowledge of which one rusts first isn't necessary, just knowing how to plan the experiment is enough, ie, keeping it a fair test by using the same volumes etc.
