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

During the exam, it took me a while to realize they reversed the order of how the questions were asked lol. Not gonna say more

It was tricky, especially the last one had everyone in the center baffled. *fingers crossed* I think I did well though.
