well yes thats wut i wrote too
I think you didn't understand what I'm trying to say. The thing is DCPIP becomes colourless but in the presence of chlorophyll shouldn't it remain green? As a result, the absorption will be at a higher level than zero. Also, the plateau reaches constant value of 0.6 au (I think) at 7.9 (or earlier) right?
yes i understood and i wrote something to that affect.
I wouldnt say it was easy, it was different tbh
The whole exam was kinda weird, with so many suggest questions, it was quite tricky
guys who did p22.....what was the order of the numbers? was it 3-4-5? and was cell 1 in telophase or was it anaphase?
it wasn't bad man...honestly i havent spent too much time studying bio and i expected to write utter shit in the exam (excuse my words) but it turned out really well (ofc some mistakes here and there) but hopefully the Marking Scheme is in our favor (same with the threshold and paper 1)
yh I think that's what i put
Was transcription and translation occurring in Interphase?
Wait it was DNA replication not protein synthesis
Nuclear envelope reforming - Telophase
Transcription and translation - Interphase
Spindles start to form - Prophase
For question 1 what 2 additional structures did u guys put?
RER and Golgi Apparatus?
what about mitochondria
That is correct too
How did u define polysaccharides?
what i wrote is it is a carbohydate macromolecule made up of amonomers knows as monosaccharide
BUT YOU had to refer to glyosidic bonds and thingy
what did to guys write about the respiratory system
mahn out of 60 how much are you expected
Not necessary for glycosidic bonds, it was for only 2 marks
I wrote about it being formed by condensation reaction by the liniking of monosachrides with the removal of water molecule
