# AQA Biology B2 Exam watch

1. (Original post by Desouza123)
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
3. 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
4. anyone know roughly how many marks is needed for a B?

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
10. for the heartbeat question did people get something like 3434 for the cardiac output

Woo! wait, do you not have to do B1 still?

For the heart beat one did u have to read off the graph when he finished exercise so read off when the graph stopped
Is that Keana desoyza???

*BLINGCLICK...remember it now - thats it ... gud memory lilheron

I think I multiplies 131 * 32

umm just chemisty and physics which is C2 and P2 soo NOPE
yay
16. Yo how were you meant to get 2 marks in the position of the genetic material question? I said its in the nucleus but wat else?
17. (Original post by Chandan1998)
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???
18. (Original post by Desouza123)
I think I multiplies 131 * 32
i think lil herons is right....its wot i got too ... but its close so ur final answer might be in the bracket IUKWIM
*not saying that me and lilherons answer is the right one BTW
19. (Original post by Desouza123)
I think I multiplies 131 * 32
i similarly did 101*32
