    I'm pretty sure that fermenter question asked for FOOD products, but either way, if I mentioned foods it should still be right....right?

    I said 1) quorn and other meat substitutes.
    2) rennet.

    Perhaps the mark for blood pressure, but probably not for tissue fluid: plasma is forced out of the flow of blood and not the cells themselves.
    i know, i seriously thought the question asked to show where the tissue fluid is >_<

    Exactly! For the cheese/rennet thing, would rennet be wrong? I didn't understand what the revision guide said rennet actually was, I put cheese and crossed it out for rennet. Oopsies.

    Don't worry too much- B7 is always people's worst module, you on average score one grade or two worse on it than the other ones since the boundaries are high (only top levels take it)
    then why is there a foundation tier if only top levels take it

    im not 100% sure but i think you're supposed to put chymosin which is the vegetarian subsititute for rennet, and i think you need to write the food that the enzyme is used to produce (cheese) you might still get the mark for rennet though!

    I hope so.

    Because some schools make all students do triple science, perhaps even some students may excel in e.g. biology and chemistry but struggle with further physics ... But are you really trying to argue it's not the top sets that do triple science (for the most part)? At the vast majority of schools only the top set or two take triple, so yes it isn't only high levels, hence the boundaries are higher and people do worse.

    did this question specifically ask to state the most sustainable method? because i just said "unsustainable timber harvesting removes food sources and habitats for organisms, method C is the least sustainable because as the cycle goes on the amount of teak produced rises dramatically which means more trees are cut down so there are less for future generations" how many marks does anyone think ill get for this?

    If you described the problems of harvesting eg soil erosion, increased CO2, loss of habitats ect you should get at least 3-4

    Is anyone else frustrated by the lack of biology we got in that exam? I'm sorry but I knew all of the content and we got asked a few flaming recall statements - there was so much biology they could've asked rather than so much data analysis.

    The two mark question specified that it was in the food industry so I think you had to put Quorn (single cell protein) and Chymosin/Rennet. Unfortunately, I forgot about Chymosin and put alcohol instead so probably only got one mark. However, I don't see how medicine like penicillin is plausible when it was specifically referring to the food industry, don't know. ¯\_(ツ)_/¯

    In my opinion you'll definitely get 1 mark for mentioning chymosin but since you said single cell protein such as yeast instead of Quorn then they may not allow it, but surely not 0 marks!! O:

    History was good thanks for asking! My hands are still dying from the intense writing in the intense heat... RIP x-x
