No worries glad I could help, thanks and good luck yourself.
I can't, I'm sorry dude, I just don't have the time with all this revision and exams.
It doesn't take long to do a plan for an essay, under an hour id say if you concentrate.

If one is on biomolecules then it will be pretty easy marks. If it is genetics it definitely wont be DNA tech but it'll still be difficult to write.


What points can you make for an essay of biomolecules?

Which PDF?
How's everybody coping with genetics?

I'm pretty confident with the essay (my practice essays have been marked at 20-24 marks), but genetics will be the death of me.
hey i was wondering what topics you could include for an essay on feedback mechanisms? so both positive and negative feedback? (I apologise if this has been asked before)

Menstrual cycle, glucoregulation, thermoregulation & action potentials all contain positive/negative feedback.

what they said and also bohr effect, stabilising selection and metabolic pathways. i guess you could also mention ACh breakdown after and action potential in the post synaptic membrane. oh and predator/prey relationships

add the values for mean rate of co2 production, 0.032+0.051+0.045= 0.128
then find the percentage for each of them, so 0.051/0.128 x 100 = 39.8%
and 0.045/0.128 x 100 = 35.2%
