it's about wht steps or observations are seen in each food test. if a step or an observation is a part of the test you(tick) it and if not then u (x) it.Oh btw, can someone explain me the answers to Q.2 of Oct/Nov 2009 5090/06? I am quite confused about the first part
e.g.heating is required for reduicing sugars so you (tick) it but not for proteins or fats or starch so you cross them.
i hope i helped ^_^

uhh.... i'm not sure!!
its just a question i had written a while ago on my notebook but didn't remember to ask. now i came across it so i asked.The indicator would turn yellow because yeast will respire anaerobically producing carbondioxide gas which is acidic in natureuhh.... i'm not sure!!

don't say left or right... it canges when the seed in inverted laterally. u can say that radicle is on the outside and plumule on the inside. like radicle is kinda touching the testa while the plumule is on the other side of the radicle.... or sumfin like that.

for presence of stoma, sandwich a leaf in between cobalt chloride paper, securing it with coverslips tied by rubber bands. the cobalt chloride paper at bottom will turn pink(due to moisture) while the one above will remain blue.
for detection of vitamin C, the question gave all the necessary details of how it is used, and we just had to add our own experimental details. If a new situation is provided, a detailed description will always be given.
