How did your Biology Paper 12 go?

[Princess Raven]

Ya

It was the option with hydrogen bonds, I think.

I chose only hydrogen bonds.. Why did everyone else chose all 3?

 

[Princess Raven]

That was A for sure they all have 70s ribosomes

What was the answer for that prokaryote mitochondria and chlorophyll one?

I'm sorry but I don't remember the question. Could you write it down so I have a better idea?

 

[Omar Haider]

It was the option with hydrogen bonds, I think.

Yeah, i did the same. I only picked one for cellulose, not all 3 or anything to do with the insolubility of cellulose. And A sounds right, at lower magnifications there is lower resolution. For example, if you were to zoom out on this very page, you wouldn't be able to make out many words, right?

 

[Muhammad Haris Ghani]

I also chose only 2 for bilayer

 

[Omar Haider]

I also chose only 2 for bilayer

Same here!

My thoughts exactly, cellulose being insoluble is irrelevant.

 

[Princess Raven]

I also chose only 2 for bilayer

dont we also chose glycerol... they are the hydrophilic group without them a bilayer cant form..

Nope it is actually. Google it. And the highest magnification power if a light microscope is 400

The highest magnification is 1500 not 400

Any one with paper 12 discussion? what were the answers for the Tar, q6 glycerol and baby one;s answers pls discuss

i went for 1500 Mag if thats right.....i started the ppr backwards but it was easy n went well .

 

[Muhammad Haris Ghani]

Varient?

Varient?

The answer for the first question was C (x400). The question was similar to the one asked in the paper of June 13 Variant 12 (question no 1).

 

[aneeq247]

For the cellulose question it was the choice with hydrogen bonds only, and for the bilayer question i chose the option about glycerol as well.

Why not x1500? because magnification and resolution are inversely proportional and 1500 is the maximum magnification for light microscope.

 

[Omar Haider]

I don't understand how it can be x400 either. Q2 was a diagram of an image at x400 magnification (with an LM) and everything was clearly visible. Unless Cambridge openly contradicts itself, that can't be the answer.

How is it at all similar to question 1.. They aren't even talking about resolution in that question

 

[Princess Raven]

I found this online according to this the answer is D
