Standard paper :smile: grade boundaries should be moderate to high, I think.
I didn't like the ambiguity of the question about rotating the compost container, though, because I couldn't tell if they meant rotating the container or the contents of it. :/

everyone's saying there was loads of unit 2? What I can't think of one question I used unit 2 in !!!
It was ok. I think i go all the marks for question 8 but there were far too many ambiguous 'suggest' questions which made a few questions a guessing game...
Shall we make an unofficial mark scheme if people can remeber questions ?
Dissapointed by the lack of emoji's in the OP.
What did people put for rq equation thing

1 and the other question was anaerobic respiration therefore more c02 is produced then o2

Thought it was a lovely paper. Grade boundaries will be quite high. Last 15 marker was great. Much better than core 3 haha.

It was a really nice paper, what did you put for the reason for turning the compost?
all I remember:
community
so theres no competition between different species
definition of phenotype: physical appearance of organism through expression of genotype and environment
XB Xb
50%
0.48%
spun container: so large clumps don't accumulate at the bottom, microorganisms are evenly distributed
hot?: bcos the microorganisms respire and give out heat
stroma
Anyone else get different answers or remember any others?

RQ=1. in aerobic respiration, there's no net gas volume change
