    Yes.
    Of course.

    Both acceptable.

    I felt it was a tough paper.
    I've been teaching biology for a decade and the wording in some of the questions was tough.

    Some of the section A questions had 10 parts to them which I felt was harsh.

    Experiments were fine.
    Drawing a diagram of the ear was a question I've never seen come up before.

    3 long questions were nice.
    3 had some horrible parts.

    Pretty sure it was how you used an instrument.

    I wrote almost 1/2 page on the capture recapture method, before re-reading the question, crossing it all out and writing some stuff about a tullgren funnel instead.

    I wouldn't accept Phosphorus.

    Sulfur helps form disulfide bridges during the formation of beta pleated sheets.

    Phosphorus is present in DNA and phospholipids.

    Nicotinamide adenine dinucleotide

    According to a google search. It's not in my textbook and I've heard of it before. :(

    Nah, only three marks for what NAD stands for. The other six marks were for the two particles it transports or something like that.

    Get a grip Chris.

    Phosphorous has chemical symbol P

    Phosphate is a polyatomic ion with one Phosphorus atom and 3 oxygen atoms with an overall triple negative charge.
    It fairly obviously contains Phosphorus.
