    The 6 mark factory farming was ideal
    I filled two pieces of paper worth of stuff for that!!!

    For the Marks:
    1 Method Stated = 1
    Advantage = 1
    Disadvantage = 1

    Other Method Stated =1
    Advantage =1
    Disadvantage =1

    and Mycoprotein doesn't count according to my teacher.

    Hi! I'm new to this forum.

    For the question about the leaf, do u think saying that because the leaf isnt connected to the stem so there is no water supply to replenish the water lost in transpiration and that the rate fell because the water had started to run out :/

    That B2 paper was much harder than the B3 Imo. How did you find the 6 marker? I read it and it specifically said digestion of fats.
