How was it? No discussions please.

Wasn't as lenghty or bad as I thought it would be.. finished it within half an hour and went through the paper =D
Alhamdulilah it went well. I'm guessing the grade threshold will be 21 for an A ..

it was awessssssssssssssome=D=D

 

[hmlahori]

expected gt? i think it will be 19-20 for an A..

btw what did you vote?

I think I messed up the last two parts of Q2!

hmm, question 2 was a bit confusing..
do you think they'r gonna accept that i finished my planning question on the next page..?
cuz if they dont i'm gonna lose at least 3 marks straight away.. and i have a feeling the thresholds are gonna be high.

ANY body wan't to discuss PM me

 

[xtremeforums]

can we discuss now?

 

[Irfan1995]

I had my exam yesterday at 3:30, it's almost 4:00 here now. So it's been 24 hours and 30 minutes.
I'd love to start discussing as soon as someone confirms its permission.

for the first question second part i wrote about serial dilution, and for the limitations i wrote that it would be hard to measure the volume of the brown area and that the brown and blue area might mix and something else, were as for the control in second question i wrote use anaerobic bacteria. what about u guys?

people, start the discussions!

what was independt variabel- area of brown staiuned agar or activity?

My limitations were-

• If the conc. is as high as 3 mmol dm^-3 the brown areas may overlap. (I also improved this in the next part- suggesting each maize grain in an individual petri dish, and then calculate the mean area).
• The areas were not perfectly circular, so difficult to measure area.
• Something I can't remember.

The independent variable was the conc. of gibberellin.
The dependent variable was brown stained area.

i rote here narrow range of conc tested for activity as dey mentioned befor seeds uses 1-10 mmol^-3 conc (so in suggestion part i rote prepare conc of 1 to 10 and test by repeating the each experiment atleast thrice and take mean for more accuracy of the hypothesis)
2nd limitation i rote the seeds were maybe of not same mass
3rd same species of maize to be used
idk hw much ill gain here =S

yea and the same goes for x axis and y axis ryt?

They information mentioned seeds use 1-10 MICROmoles, not millimoles.

well i dont remember dat nw bt i rote da unit as it ws given in da ques dat tym nd i hv a strng filling it ws milli:/
