Hey, does anyone know which years are the most important to study for practical 32, I can't study everything because I also have a maths exam.
Thanks!:)
although its not advisable to skip stuff :
do the recent years M/J 10 11,09 and o/n 101109 try doing as many variants as possible
go through dilutions and food tests
scan through any examples of plan diagrams that you may have

prepare the space in a suitable form (table-venn diagram etc)
make four columns -one for feature and three for observations from each slide
think of all the possible differences you can see between the cells -these are usually the likes of shape , size etc
write down at least 5
Thanks but I think you read the wrong question... It's the one about the stage micrometre :)

Thank you! Quick question about food test...

For proteins, we add potassium hydroxide and cooper sulphate?
For non-reducing sugars, is it add HCL then heat, cool, add NAHCO3 and benedicts solution then heat again?

Thank you!
