How did your Biology Paper 12 go?

[Muhammad Haris Ghani]

I don't remember the option but the sequence was Ribosome -> ER -> Golgi -> Cell membrane

Tar contains carcinogens which attacks DNA which includes genes for cell division thus developing lung cancer. So yeah, I think A was the correct option or whichever one it was.

sorry brother the mcq was a repeated one starting from ER

 

[Muhammad Haris Ghani]

wasnt paper 12 different and difficult this time biology

 

[Omar Haider]

Sorry, why is sucrose actively transported? I thought it always diffused from the companion cell to the sieve tube elements. And I put the same for Q6, ribosomes and ER must come first and second, respectively. It doesn't make any sense otherwise.

 

[Omar Haider]

Which one was the plasma membrane one? Think I forgot :/

 

[Princess Raven]

what about plasma membrane one I chose (C) starting from chemical receptor and ending with maintains fluidity

Yea I chose C too that question was really tricky... And what did u chose for the second magnification question?

 

[Muhammad Haris Ghani]

good luck

I chose D but think am wrong

 

[Princess Raven]

No it starts from ribosomes I solved this question before

 

[Princess Raven]

I chose D but think am wrong

I think I chose A.. Yea I think I got that wrong as well.

 

[Muhammad Haris Ghani]

I think I chose A.. Yea I think I got that wrong as well.

what about the glycerol one I chose B q7

The answer to magnification question was option A .. something like 0.1*10^1 I don't remember.

what about glycerol one q7 chose B

Listen, Logic > ratta. It doesn't matter if it was repeated, if my answer makes sense it's correct

What about glycerol one B

 

[Fallen316]

What about glycerol one B

Which question? I don't remember :/

 

[Muhammad Haris Ghani]

Which question? I don't remember :/

what about that gametes one in which chromosomes decrease or may increase I did 1-3 and 4

Don't remember, not sure...

 

[Muhammad Haris Ghani]

Don't remember, not sure...

do you remember any

 

[Muhammad Haris Ghani]

Don't remember, not sure...

Don't remember, not sure...

what about that bohr effect one I chose that carbon dioxide increases 02 release D I think I am wright

 

[Omar Haider]

I chose D for the bohr effect one too. And it starts off with chemical receptor? I thought it was antigen. Proteins contains gylcoproteins/glycolipids which are chemical receptors, but antigens are just connected to the membrane, no?
