The deadline will be the day of the practical, although most schools like it in beforehand.

Nope, but I people in my bio group were planning it today, they seemed ti be awfully confused over it... I can't really see any points that would cause problems though...

Things are so much easier when you *ask* for what you want instead of asking for non-specific things. Do you want help on the format/theory/practical component?

want help on the method and expected results (prediction) - (i have a rough idea but it has to be detailed and i'm stuck with measurements etc) :confused:

PM me please! :redface:

(increasingly desperate as just found out the deadline 4 me is 4th Jan!) :afraid:

Hi, I'm retaking the AS OCR biology transport/practical module in Jan. i've just been given the planning exercise today and i am totally confused! Last year's planning exercise i found ok, but this time i'm really stuck :frown:

The question is:
The enzyme urease catalyses the hydrolysis of urea to form carbon dioxide and ammonia.
The progress of the reaction may be followed by observing an increase in pH as ammonia is formed.
Thiourea is an inhibitor of urease.
Plan an investigation to measure the inhibitory effect of thiourea on the activity of urease at different concentrations of urea, based on the assumption that you have:
0.1% urease solution
solutions of 1% urea and 1% thiourea
Universal indicator
In your plan include apparatus and materials used, method including how to make it fair, results table with expected results and safety precautions.

Anyone else having to do this at the mo? Would appreciate it if any ppl doing biology who find this kinda thing easy could reply or PM me with anything useful that might help me answer this! (Really desperate - plz help me ppl!) :redface:
