    as haemophilia?


    In Q7 whats is used to add a small volume of a solution?


    How does digestion contribute to successful seed germination?

    What's the approximate percentage of water in a human cell? I do not remember covering this. I stuck down 70% because I vaguely recall that number from some quiz.

    Males.

    Dropper.

    The products of digestion are used by the embryo in the seed, so the embryo can grow in result of the digestion of food reserves.

    To activate enzymes in the seed.

    It just said name two biomolecules.

    That's like saying, give two elements of glucose.

    Jesus, is everyone on this subforum a neurotic type-A personality, fastidious nerd? I know I am, but JESUS LADS, CALM THE F*** DOWN.

    99& of the questions you're asking can be found in the book.
    It's not the end of the world if you didn't get right.
    Water makes up 75-80% of cells.
    The definition for NAD is very clearly stated in the book.

    1. What were the percentages for the genetics short q?
    2. What's the interphase question answers?
    3. What's the function of red and yellow bone marrow?

    I swear you're better off looking in the book!!! It's physically faster to go into the book and read the answers.

    From recollection, something like 0, 75. 50
    Makes mitochondria
    Replicates and is coiled by the end
    Red - makes blood cells
    Yellow - Stores fats/ makes blood cells (when it is activated) I prefer saying stores fats, though.

    Eh yes I know it is but I can't recall ever being tested for what NAD, NADH, NADP or NADPH stood for. I know exactly what they are and what they do but I don't think I've ever seen an exam question asking for what they stood for.

    Yes, discussing, not
    a) wringing hands
    b) telling teachers who have taught for 10 years that they're wrong
    c) spamming endless questions in separate posts.

    Yes, that's it. Surprised more people didn't just draw punnet squares. It was fairly simple.

    Exactly.

    Even my teacher was surprised and said that every year there's a question on something which isn't directly on the LC course.
