    Did you get 85mm for the measured length?

    I got 85mm when i first measured it, but then measured again just in case and got 84mm
    Ugh I don't know what I did wrong then.
    I got around the answer Lily got but not exactly. Think I got something like 2145?!

    For the function of Y question, I said it also acted as an enzyme as substrate went in and cellulose came out

    This stresses me out. I don't recall seeing any function of Y question

    I calculated the magnification to be 2100x, as the length was 8.4mm (8.4x10^-3m) and the actual length was 4um which is 4x10^-6m.

    I did that. It was only after leaving the hall I realised that it's only for HIV testing

    Looking at that graph, it seems wrong in many ways.[/QUOTE

    I multiplied all my standard form values by 1000, I got answers like 1.2, then plotted the graph. I don't remember the question saying you had to plot the graph as standard form, just to write the answers in the table as standard form, pretty sure my teacher said you could do that if you got horrible numbers

    Did it not say the B secretase also increased where the question said that the mutation led to A secretase decreased? You know on the last side of the paper. I wrote then add sequence codes for different amino acid sequence which leads to different primary structure so more B secretase is made so more B protein so more plaques in brain.

    I did Eliza test, cause my thinking was you can then use colorimeter to get results😂 and it's not just for HIV that's just an example in the text I sware?

    Wise move.
    Had to deal with the worst numbers and took awhile trying to decide what my scale should be coz I didn't think of that.

    The Y axis is always Dependent (Variable), which was the rate of the thing that was being produced.
    For the X Axis, it was the number of days, ranging from (0 to 12).
    The Y Axis had values that were in standard form
