ohhh i thought you were talking about p33 sorry about thatbut then it depends on the variant as jed had 31 and u have 33

You know for the enthalpy experiment ... were you meant to take a temperature reading of the initial without any FA3 added and then calculate the difference or just take temp after adding 5cm3 and then the difference between highest and lowest? :Show was chem 33? i think i'm losing marks in tiration
it will be based upon the turgidity of a slice of a potato after you place it in a dilute solution and then in a concentrated solution, more like dilution .. you will have too make solutions of different concentrations, you 'll have to measure the length of the potato strip or slice after carrying out the experiment with each solution that you will make !! revise this from the o level coarse book ...
we were asked to take the initial before adding FA3 , ie. after adding FA4You know for the enthalpy experiment ... were you meant to take a temperature reading of the initial without any FA3 added and then calculate the difference or just take temp after adding 5cm3 and then the difference between highest and lowest? :S

Yeast has always been problematic. You mean that your school is the centre? that's cool.lstn, what i know about zone 3 or to b accurate in my school, the questions will be based upon Starch and Benedict's Test and Magnification..
We haven't got anything related to yeast in the ir report
your teacher may be a supervisor for Biology 33 variant practical, right?Yes he was sure of it.. yeast will come with no syringe and pipe... but some type of glass tube... he was sure of it. (I am not of 33 though)
Are you sharing guess? You seem quiet sure about it,it will be based upon the turgidity of a slice of a potato after you place it in a dilute solution and then in a concentrated solution, more like dilution .. you will have too make solutions of different concentrations, you 'll have to measure the length of the potato strip or slice after carrying out the experiment with each solution that you will make !! revise this from the o level coarse book ...
oh, okay. I thought he kind of gave you people a question type.nah! our teacher made a practice ppr based on that..and how do u expect me to see? lol
Great, I'm confused. Is yeast the part of 33 variant?oh thankgod! the misunderstanding is clear or else u would end up not studying yeast
your school is taking 33 variant?lstn, what i know about zone 3 or to b accurate in my school, the questions will be based upon Starch and Benedict's Test and Magnification..

Yes he is...i'm not giving a guarantee that yeast is coming but be prepared is all i can say as of course there is a chance.your teacher may be a supervisor for Biology 33 variant practical, right?
well this is what my teacher told me ...Are you sharing guess? You seem quiet sure about it,
