Why is 38 B option not correct?
every gene encodes for a specific protein that has it's distinctive function, I never heard this though.
I know what the ER says about option B, but sarey bacteria resistant ho jaen gey to phir?

what would happen if the bacteria becomes insulin resistant...its not like insulin help us in fighting bacteria.........

 

[funky brat]

that is but everyone knows that it is it
you cant use umbrella for playing cricket, is that umbrella's fault?
it should be immune but cie no accept it

Exactly, this is very illogical to say that it's the problem with the umbrella if you can't play cricket with it.

If the bacteria becomes insulin resistant, it would not be affected by the gene we inserted, it won't respond to it. That's what we mean by resistance.

The main purpose is to identify if the candidate can see that secretion is slowed or stopped,we dont have to go into the technicalities

So how the hell do we know when exactly we need to go into the technicalites? Is there any way? I've tried doing MCQs without going much far but sometimes they do actually require.

I did get full in the mocks,hopefully same in CIEs

What kind of a Q can come relating to SCP?I mean there isnt a single q in past papers and we havent studied it in depth in school either.

It would be related to fermenters if it came, I think.

and look at their thresholds
even lower

Why the hell didnt we choose igcse.....

Competition, dude. Wese bhi maza nahi ata itna easy.

Try imagining what happens when you close each switch as in the options. Only switch 5 completes the circiut.
