    OMG GUYS IT WAS SOOO EASY
    just to clarify

    the infertility question answer: overproduced mucus blocks some enzymes from exiting the pancreas so the enzymes can not break down the essential nutrients needed for testosterone resulting with infertility due to a lack of nutrients needed

    You ask the questions you want to know the answers to, I'll try to tell you the answers from what I know people have said
    Okay, can you please tell me the answer for the bar thing where you had to describe the ph of the organisms?

    I wrote that if there would be low ph- bad indicator of water pollution would be there, something like that. 0.0

    The answer was most organisms couldn't survive in an acidic environment. Only frogs could.

    The CF infertility question was not in the Edexcel specification and multiple schools are complaining to edexcel... judging by the amount of people that thought this was an easy paper the grade boundaries will go up but hopefully will go down 1 or 2 marks due to the question, thank you Edexcel. The year of 2015 love you lol

    That question wasn't meant to test your knowledge on the specification, it said "suggest" implying you had to use previous knowledge on cystic fibrosis to make a judgment. It's all about applying skills.

    Ok, I am going to use my knowledge to predict that the 'vas deferenes' does not develop properly? I sure hope you got it right... I know the whole of topic B1, every symptom of CF... no knowledge of mucus is involved whilst explaining the infertility of males within the disorder.

    I got the process right, but mixed up the names of glucagon and glycagen. Roughly, how many marks will I get.
    Id say around about 4, as it was out of 6. 1 mark is awarded for the way you've written your answer, and your small mistake would have only cost you 1 mark
