Ace the practical. Its easy.
Mcqs are easy too so try getting around 32. Dont panic if paper is difficult.
Last year it was so difficult that everyone was like what is this crap and threshold dropped to 25!
But key is to never panic and keep your pace reaally fast in p2!

New housing was correct? There wasn't sufficient information that new housing would decrease the population. I think that was more of related to cholera as then new housing makes new contamination and sewages. No?

Not sure :/
Your point is correct too. So you chose pasteurized milk only as the answer?

What about ecoli one?

 

[Rohan O]

And for the rRNA molecules, answer was 19000? Or 38000? I did 19 because it said that ribosome has 2 subunits EACH having a rRNA molecule, something around that

Can you remind what the question was?

Many people say its 19000. Nobody was dead sure though.

[Abdul Hanan]

what was the one about bronchus? the option with cilia paralysis? or cilia inhibition?

 

[Rohan O]

I wrote cilia inhibitor and goblet cells more active, don't know which option it was.

 

[Abdul Hanan]

I just checked on internet. Its 19000

if its 19000 for sure its 1 mark free for me i shaded C blindly without looking at the Question

 

[Rohan O]

Lol lucky you. 19000 was B btw 38000 was C

 

[Abeha Malik]

I wrote cilia inhibitor and goblet cells more active, don't know which option it was.
