Was the answer for that Open Loop system? PLEASE TELL ME IT WAS.. crossed out closed loop as you'd require water..
Does anyone have the 2014 mock specimen paper for C7?
I wrote open because he would have to put the fertiliser in in the first place to see the difference :s i dont know though
Are you sure there wasn't one?
Wasn't the one where patient B had a high level show that is pancreas wasn't producing enough insulin (diabetic)
I put open loop because he added an input (fertiliser) but no outputs balanced it
