    Can someone please explain pollarding and coppicing?
    Thanks
    coppicing is when you cut the trees close to the ground so promote regrowth
    pollarding is V simular, but its done further away from the ground higher up in the tree to prevent the regrowth from being eaten e.g. by deer

    How do you know if dominant epistasis is 13:3 or 12:3:1
    You'll typically know from the context - if there are three potential outcomes of epistasis, it'll be 12:3:1, otherwise it's 13:3.

    The difference between 12:3:1 and 13:3 is that when both genes are recessive, it produces the result normally seen by the first dominant gene. 13:3 is most common when the first gene being dominant blocks any protein (pigment etc) production, so then the double recessive offspring (aabb for instance) also blocks any protein production.

    so can someone outline electrophoresis in bullet points and DNA sequencing
    electropheresis is used to seperate DNA fragments based on their size
    This is necessary for identification and analysis
    1)DNA samples are treated with restriction enzymes
    2)Then placed into wells at the cathode (negative part) end of the gel
    3)The gel is immersed in buffer solution
    4)As an electric current is passed through the solution DNA fragments move from the cathode--> anode (DNA is attracted to the anode because it is negatively charged)
    5)shorter lengths of DNA move faster and further though the gel matrix, separating them out in order of length
    Then often a dye is used to stain the fragments so they can be seen even more clearly.
    Hope that helped!

    Must we need to know the experimental work done into the effects of gibberellins on stem elongation (pg.225 in the Heinemann txt bk.) in detail? Because I just can't get it into my head at the moment.

    You just need to know that cytokinines inhibit leaf senscence, however drop in auxin causes drop in cytokinines and makes the abscisson zone more sensitve to ethene. drop in auxin means increase in ethene production and consequently more cellulase. cellulase digest the cell walls in the abscisson zone and eventually the petiole separates from le stem.

    Also, in the Heinemanne book (page 195) it says how 'different species may release different amounts of energy per unit mass - hence, this method (pyramids of biomass) may not be accurate'
    Could anyone explain what this sentence actually means?

    same here and then i just keep finding more things i dont know about then have to stay up longer to do alll the work
    I'm just risking not learning it

    a night of sleep will probably benefit me more than trying to cram a whole syllabus which I'm not going to remember

    resigned to the fact I'll get a U

    This isn't maths where you need to be sharp to understand the questions, it's mostly fact recall. Even if you remember 30% of what you looked over in the extra hour before bed, that benefits you more than nothing imo
