my practical teacher told me that yeast was coming for sure..in p33. maybe he was wrong then.

but then it depends on the variant as jed had 31 and u have 33

ohhh i thought you were talking about p33 sorry about that

 

[Mimick]

ohhh i thought you were talking about p33 sorry about that

oh thankgod! the misunderstanding is clear or else u would end up not studying yeast

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? :S

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 ...

which paper are u talking about?? 31 or 33?

we were asked to take the initial before adding FA3 , ie. after adding FA4

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

Yeast has always been problematic. You mean that your school is the centre? that's cool.

 

[bubbles1997]

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)

your teacher may be a supervisor for Biology 33 variant practical, right?

Are you sharing guess? You seem quiet sure about it,

oh, okay. I thought he kind of gave you people a question type.
What about the potato strips?

 

[bubbles1997]

Great, I'm confused. Is yeast the part of 33 variant?

your school is taking 33 variant?

 

[Abdul Hanan]

your teacher may be a supervisor for Biology 33 variant practical, right?

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.

well this is what my teacher told me ...
