For the 5 marker what did u lot put?
I put something along the lines of Runner 1 had more heartbeats so more oxygen more aerobic respiration which helps the muscles contact. He also had more blood flow so this removed more lactic acid which prevented anaerobic respiration

Sounds v similar to mine ... also i think runner 1s heart beat decreased quicker meaning he was fitter so cud run more IUKWIM

You had to measure the scale. It was 4cm so:
4x10=40
40/0.1=400

I'm pretty sure it was that

I got the same answer of 400x

I said 40 not 400
i put homo homo hetero
the 6 mark on leaf sampling seemed vague but I wrote loads
for the graphs I drew a horizontal line second and a gradually reducing curve
hope I got a star
i recon there'll be quite a gap from a to a star in the grade boundaries thooo

It was 148 * 38 = 5624 right? Or something like that?

what did you all do for the ratio question??/

Divide by the smallest number with both. So 224 (or something like that) divided by 224 gives 1. Then,750 dived by 224 gives 3.14... something.

So the ratio of 750:224 was 3:1. I assume, ahaha.

Too much Maths for a Biology paper

For the 77 one, you had to go up and to the left because it was when exercise finished. My exam went quite well as I had learnt speciation off by heart!! Hope I got an A/A*

so was it not 77???
