    Friggin' frogs.
    I put that the pesticide would mistake the small egg for a pest... and I genuinely thought that it made sense at the time.

    I also thought that the DNA base pairing thing added up to 100, and pretty much realised my mistake when we got told to put our pens down. My brain melted.

    Now it's my turn to ask a question
    What did you guys put for the second part of the frog eggs question, about what effect evaporation of water had? I put the concentration of pesticide increased....
    And also, what about the question asking why ten leaves were used in the experiment, measuring water loss in milligrams? For that, I put because the change in mass of one leaf is too small to measure, so ten leaves allows a significant change to be measured.

    ...or similar words to that effect
    10 leaves means the average is simply a division by 10 of the total. And for the frog thing I basically wrote the same thing as you. Less water=greater concentration of pesticide.

    The organism only had one large chloroplast, rather than many

    Did anyone get stumped on the DNA question with the number of base pairs I probably spent longest on that one I had to draw 2 strands of DNA and everything to get my head around it!
    they asked it different to past papers at first i was like :confused: but i think it was 74 pairs - i remember getting 20 and 9 and matching the ans A-T and C-G for complementary fit

    It did but 2 strands. so 74*2=148

    Strand A was 26 26 20 20
    Strand B was 19 19 9 9

    I think...

    I hope I got the marks :afraid: Yeah I didn't even know what the diagram was tbh. :facepalm2: so failingatm.


    Lol, yeah hopefully grade boundaries will be low. :afraid: But it was an easier paper than Jan 11. I feel sick now
    I hope so, I thought it was harder than Jan 11 though, and I need 121 UMS for an A overall. I felt fine until I came on TSR >.> I hope we both did okay!
