    i'm very sorry to say that there won't be questions pack on module 1, however i will do questions pack for module 3 hopefully by tonight :cool: the reason why i won't do it is because i need to concentrate on making questions pack for physics
    which is to me ten times more important

    Can someone help me answer this question

    'Give an account of the process of Meiosis'

    this is what i wrote so far:

    Meiosis is a type of cell division(reduction division) concerned with producing gametes and introducing variation(through crossing over, random assortment etc) in an organism. Meiosis aims to produce daugter cells that have half the original number of chromosomes(Haploid). This allows sexual reproduction to take place. Although the process of meiosis is continuous, it is conventially divided up into a number of stages and sub stages i.e. Prophase I-II, Metaphase I-II, Anaphase I-II and Telophase I-II. Certain key events happen in each stage as follows: In prophase I, .....:p: how is this for a start?

    hehe I'll be starting them this weekend, been slacking on chemistry and maths so I need to catch up on them before I get onto Bio, I'm happy to see that they helped

Certain key events happen in each stage as follows: In prophase I, .....:p: how is this for a start?
    From what i can recall:
    Pro-phase 1:
    The chromosomes condense at this stage to thread like structure.Also bivalents form during this stage and formation of chiasmata albeit invisible to the naked eye.

    Pro-Metaphase 1: Chromosomes condense enough to appear visible.Centrioles form.
    Meta-Phase 1:Nuclear membrane dis-integrates,spindle formation takes place.
    Ana-phase 1ach half of the bivalents are detached i.e taken apart in this stage.(This is the stage where the no of. chromosomes halves).
    Telophase- 1: Chromosomes de-condese,Nuclear membrane re-appears.
    Cytokineses 1: Two Nuclei daughter cells formed, with each cell containing one part of the homologous chromosome.

    .
    Prophase 2: Chromosomes condense(same as in ps1).
    Meta-phase 2:Nuclear membrane dis-appears,chromosomes attached to the centrioles move to the equator.
    Ana-phase 2: The centrioles pull the chromosomes across in such a pattern that each chromatid gets separated or you could put it this way: The centromere divided such that each chromatid gets pulled towards the opposite end.
    Telo-phase 2: This results in the formation of 4 daughter nuclei each containing half the no. of chromosomes compared to the parent chromosome.Spindle disappears again.
    Cytokineses 2: Plasma membrane forms around the 4 daughter cells,nuclear membrane forms.

    Module 3 cosystems and sustainability:
    Ecosystems: is the group of living organisms and the non living things and the inter-relationships between them.

    Habitat: a place wher an organism lives
    population:a group of organisms of the same species
    community: a group of organsims of different species and that can interact with each other

    the role that each organism plays on the ecosystems is called a niche.
    Biotic Factors: Food supply, predation and disease
    Abiotic Factors:PH, Temperature and soil type
    Eosystems are Dynamic
