Was the answer "fats" or "Water" in biology paper 1 ?

<< < (18/26) > >>

:) OpAsi:
Ok look guys think about it, what is sucrose?
Its a carbohydrate
What happens to sucrose when its is changed by enzymes
It becomes an individual glucose molecule
What happens when an organism (An Aphid in this case) has an excess of carbohydrates
They are stored as Fats
And so if the aphid is eating the phloem it will rightly obtain sucrose
Which can than be stored if in excess as fats
Thus meaning that fats cannot be the answer
Allowing us to conclude through elimination of the obvious first two and now Fats
That water is to be lacking.
Am i right... Think about it  ;D

Nice Explanation but dont think so
glucose can be changed into glycogen and stored :P
And what if it didnt feed on excess of carbs?!!!

molii:
its definitely water.. :)
isnt fat immobile..?
wat wud it be doing in the phloem?

it shud be water i guess...

wat say guys..?  ???

unknown:
i actually dnt care abt d explaination as we r nt getting marks on it
my only concern is tht ma ans shld be correct n tht is water.......

nid404:
water cannot be lacking cuz all substances in phloem are transported in a solution. Plz don't repeat the mistake again in ur paper 2morrow.
