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*

For the magnification question you were supposed to messure it horizantally not vertically so 7cm
7×10=70
70÷0.1=700

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

I'm pretty sure it was that

0.1mm (scale) = 4cm

4cm = 40mm

40/0.1 = 400

Anyone else get this for magnification?

I got this too

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
