    No. Not a silly question at all.

    We are given the article. The article is released months before for students to get comfortable with it because it's too long and although you may find the time to read a paragraph or two, the chance of having enough time to read the whole article during the exam is very low.

    Well if you've done coursework as unit 6 then read GCE one called "factory of life" but if you've given unit 6 paper then read the IAL one "ageing and disease"

    Do you think most of the questions in the biosolutions thing would come up in the exam? Like are the biosolutions papers accurate enough in previous years?

    Can someone please help me with these li'l questions?
    Puhleeeez
    Attachment 552752
    What are those? xD
    Attachment 552752552754
    In this second thing I thought it'd be B cuz fast twitch:slow twitch should be 6:18 and hence 1:3 but markscheme says 3:1
    (the lighter ones are fast twitch and darker ones slow twitch)
    lastly Attachment 552752552754552770
    They asked for ans. in dm^3min^-1 but stroke volume is in cm3min^-1 so, it should be 4.608x10^-6 but ms says 4608 (cardiac output=stroke volumexheart rate at rest)
    For the 3rd one ; you will get 1 mark for 128×36=4608cm^3/min
    The 2nd mark goes for conversion. Just divide the answer by 1000 which is 4.608 dm^3/min
    And stroke volume is in cm^3 per beat while heart rate is in beats per min
    So now multiply the units the "beat" in stroke volume and heart rate cancel off leaving you with cm^3 per min

    umm no first question's answer was 'three myofibrils' (I wonder why)
    I get the second one thanks.
    Could you solve the third thing and send me if you don't mind?
    Biosolutions are predicted questions and answers from the article and yea we have the IAL one only!
    So for the 1st one; a myofbril has so many sarcomere units which can be seen in the diagram. Then you have those white areas, those are the sarcolemma and other organelles such as mitochondria can also be present. Between two myofibrils you get the sarcolemma(white area in the diagram) so 3 myofibrils and each hs like 2 sarcomere ( 1+0.5+0.5)

    So after reading through 23 pages, what I got was this super helpful dude Aimen is giving out mock question 7 material for bio U5. How and where do you send it to? It'd be super helpful if you could send it to me as well, but you probably got it the past 100 times you were asked.

    P.S did anyone else hate the unit 4 exam last week, or is that just me? xD

    Do you guys really think the biosolution thing is useful?
    The questions seem repetitive and nowhere near the style of questions edexcel would ask.
