    What do you mean by 'finish' lol? Do you mean doing all the questions and reading up about everything or just covering the topics?
    Topics,isn't module three based on ecosystem ?

    I have covered everything (apart for gorilla relationships and dopamine in the brain because to be honest it really is just MEMORISING.) After my F214 resit I plan to go through all of it again and this time do the past paper questions and end of spread quetions in the Heinmann book. After that then I will basically do the june 2010 paper and specimen.

    Heres my guess on the topics that are most likely to come up ^^
    genomes
    genetic engineering
    apoptosis
    behaviour
    muscles
    brain and nervous system
    lac operon
    variation
    artifical selection, natural selection
    cloning
    gene therapy
    succession
    sampling
    nitrogen cycle
    meiosis
    and of course some form of punnett square lol

    We had chi sqaure last time.Nothing on muscles,there was a little bit on genetic engineering,homeobox genes. No animal behavior either,so there's a chance of it coming up...
    oh I have a feeing that the paper will be variable :P in terms of topics... hopefully

    From the spec:
    describe one example of primary
    succession resulting in a climax community;


    In the mary jone's book two examples are given:Glaciers and sand dunes.. do we need to know both or just one ?
    I find glacier easy to understand.

    Right let me put down stuff on succession....

    Succession is the gradual,directional change in a community over a period of time.Every successive interval of colonization by different organism's is called seral stage(too much wordy).
    Primary succession is where an area get's colonized which was previously devoid of life,soil.Secondary succession happens when an area has soil and changes in the distribution of species occurs.
    Example of Primary succession :Glaciers
    Glaciers when retreat leave debris of rocks of different sizes called moraine.Moraine first gets colonized by mosses,dwarf willows and mountain avens.These first batch of organisms are called pioneer organisms.Pioneer organisms are suitable to this rigid environment.Their roots easily penetrate through rocks and their dispersal of seeds makes them easy to colonise.Over the period of time as these shed flowers and leaves hummus starts to build up.This causes the soil to become stable and hold more water content.This lures shrubs as a result shrubs over take pioneer organisms.Pioneer organisms can't compete in terms of getting enough sun light since shrubs are taller.Later conifer trees over take shrubs.Conifer trees can't produce nitrate ions so their survival depends on how much nitrate content the soil had.This content was built up by mountain avens which have nitrogen producing bacteria in their roots.
    Ph at the begging is at 8 which decreases as more nitrate begin to be introduced in the soil.The soil becomes acidic which kills pioneer organisms. The climax community is conifer trees/spruce which are stable as long as the soil drains.


    Abiotic factors affect in the beginning of succession such as soil PH,water availably,sunlight.As successive seral stages are found biotic factors take role (competition)

    Explain what's meant by carrying capacity?
    It's the max. population size achieved by the environment over a period of time.
    Is this correct ?

    Almost done with module 3 YAY!! GETTING THERE.. ROFL.. I will write down notes on nitro cycle,bit on Galapagos stuff and conservation (meh i hate wordy modules.. )
    I guess it should be all obvious to you people that I pulled another all nighter.

    Jesus, you animal lol. I couldn't take it, fell asleep :/

    Carrying capacity sounds fine. The environment is supporting the maximum stable population size it can.
