Exam Is In A Few Hours, How Are Your Preparations People?

I Hope It Doesn't Come As Stupid As Physics Paper 1 :S, but thank god we did well in the two other papers :)

i have a question my self in the past papers, june 08 Q's 27 & 35.

Thanks

for Q 27

phloem sieve tubes have a more negative water potential(low water potential/dilute)

so when solute potential is high water potential is less negative and when solute potential is low water potential is more negative

so answer is C

for Q 35

the question mentions something about drugs having a similar molecular structure to DNA nucleotides

that removes option A and D since they are treated by antibiotics

and i don't think that malaria attacks the DNA itself

so the answer is B
