    Biological species concept - organisms who look similar and are able to interbreed freely and produce fertile offspring

    Limitations -Not all organisms interbreed, e.g asexual reproduction in ulmus procera
    -Not all organisms look similar e.g male/female peacock

    Phylogenetic species concept - groups organisms, based on biochemistry, morphology, behaviour and embryology >

    cladistics - grouping organisms based on evolutionairy history.

    kind of unsure on this spread, it's very very badly worded in the heinmann book.

    Okay.. and golden rice? :confused:

    I thought the definitions of the biological species concept and the phylogenetic species concept were the other way around?

    Biological species concept - organisms who are similiar in appearance, physiology, anatomy, biochemistry and genetics, and who are able to interbreed to produce fertile offspring. They also remain reproductively isolated from other species.
    Phylogenetic species concept - organisms who are geopraphically separated and morphologically and behaviourally distinct from other species, even if their breeding capabilities are unknown.

    fancy doing the same for Jan 11?
    I'm in the process of doing so...but there is a big hint for you MODULE 1 CONTENT CELLULAR CONTROL is what you must focus on....the emphasis on past papers is'nt really effective as it was...alot of the questions are relatively new...although it is still good practice...as the PhilipAllan conference they said they merely have 'adapted' past questions for the practicals and the written hmmm Though it is quite true since the A2 Photosynthesis practical was indeed adapted from a past paper...there's no reason why they can't recycle past questions...

    Haha thank you! I'm sure you will be too
    Yeah, at least for the summer! At least we won't have OCR writing our uni exams... and it'll be all my favourite bits of biology so I'm happy
    :yep: .. What type of Biology are you doing?


    Same, I don't think I've ever revised more for an exam but I still feel like I know nothing..
    never mind we'll be okay, just keep going
    Ah, but when you're in the exam, your sympathetic nervous system kicks in, increasing blood flow to the brain :awesome: .. You'll suddenly realise you remember lots of stuff!

    Unless your asked A question, worded so horrible and vague that you end up leaving it out. Even though its simple biology, if i say. Errrr OCR :eek:

    Chemical Biology me :yep: .. Lets me do Chemistry while getting in some immunology modules :love: .. Zoology sounds amazing though

    And your brain won't let you down in such an important situation :noway: .. After watching loads of Biology programmes on Discovery, I'm very sure of it :holmes:

    I'm trying to work out the mark I roughly need to get on the paper, so I'm trying to work out my current UMS.

    How do I do the weighting/etc? Like on my results from my sixth I have the mark, I assume this is UMS? What's the UMS out of for the Jan/June papers?

    And for the ISAs? I had a quick scout on OCR, but I'm not sure where to start.

    Thanks

    Functions:

    Voluntary - To move bones/joints/limbs.
    Involuntary - To control organs/glands/arteries etc
    Cardiac - To pump blood!

    Structures:

    Voluntary - Multinucleate, Cylindrical cells.
    Involuntary - Uninucleate, Spindle shaped cells.
    Cardiac - Uninucleate, Branched cells, lots of mitochondria.


    There's probably more, but that's a basic thing of it
