    Guys i have a couple of questions....

    1) what even is a polymer (I know stupid question)
    2) What would you include in a carbohydrate essay?
    3) can somebody please explain taxis/kinesis to me briefly, along with stem cells?

    thank you so much! Willing to help with anything if I can x
    A polymer is just a large molecule made up of a repeating unit e.g. Proteins
    For the carbohydrate essay I'd put like all the AS polysaccharides (e.g. Cellulose, glycogen, starch) and link to A2 topics like blood glucose control and plant cells etc and then obviously respiration and photosynthesis for glucose etc
    Taxis - Directional ( I remember it like a taxi has a direction to go in)
    Kinesis - Undirectional or random movement
    Hope this helps!

    I'm gunna do so badly on this exam. I know 80% of the content but I still flop the past papers. I just hope it's content mainly and an easy 25 mark essay. Last exam, hopefully I can finish on an OK note.
    Dont get stressed out. Quite often the Grade boundaries can be reasonably low for this paper. Last two years has been 67/100 for an A*

    Seems pretty unlikely as they're too restricted, maybe carbohydrates but definitely not lipids

    Did we settle the debate of what a kinesis was? The way i'm seeing the two ways of describing it is 1. the organism is in favourable environment so turns lots and rapidly to stay in that environment (kind of like going round in a circle if you will). or 2. the organism is in unfavourable environments, so moves and turns lots and does this quickly to increase the chances of it moving out of that area?

    Because i thought you'd have more chance of getting out of an unfavourable area by just going straight rather than round in circle if that makes sense?

    Please can someone clear this up? Thank you

    Number 2 is more accurate. A kinesis is where an organism responds to the level of intensity of a certain factor in an environment, and if this factor is unfavourable, then the organism will move rapidly and change direction constantly to increase its chances of moving from an unfavourable area to one with a more favourable environment

    You're right whoever tried to argue against that case is wrong, of course you don't turn more in an unfavourable environment

    Ahh help, I understand the biology but half the time I don't know what they're getting at with the questions, last year there was a 4 mark question on PC that i couldn't even attempt when we did it as a mock, even though I know the stuff on muscle fibres and PC..urgh
