How did your Biology Paper 12 go?

[Snowysangel]

Cellulose was all 3....doesn't glycerol also help in making the bilayer? I mean its an essential component of a phospholipid

If I got 42 in paper 2 and 30 in paper 1, can I still score a?

Highest overall threshold is around 95/130, so 42+30=72. You need to get more than 30 in p3 for a confirmed A as they convert your p3 marks to out of 30. But last year the threshold was at 82 so you still have a chance if your p3 is not that good.

For the lipid bilayer one, I only put 2. I'm sure the membrane only depends on the hydrophobic tails. I also chose Emphysema and lung cancer, made the most sense. I chose A for the membrane one, not sure why haha. And what did you choose for that cellulose question?

I chose A which was all the statements

what was the cellulose question?

yes of course theres glycerol in bilayer

i

It was okay I guess the fluorescent question etc was confusing for me. I just hope we get an A In it Insh Allah. How'd paper 2 go?

i selected the option D... what have u done?

 

[maryam fatima]

I hope the grade boundary isnt too unforgiving. 4-5 were confusing
What was the answer to the first question btw? The magnification-resolution thing? I gave ×400, cause it seemed right, images get blurrier when magnifications increases right? Im so confused.
and is ×1500 possible with a LM?

i did D and after paper i checked it in campbell biology, there was a statement: image becomes increasingly blurry when u increase the magnification of a light microscope...

only if the gt falls... otherwise u'll get B

C x400 was it correct

 

[maryam fatima]

C x400 was it correct

i talked about this question with my teacher and there's 90% chance of option D being correct...

Did u talk to her about the plasmodium question? Or the lipid bilayer one?

 

[Omar Haider]

Did anyone put A for the first question?

 

[Princess Raven]

Did anyone put A for the first question?

Wasn't it D..

 

[Omar Haider]

Possibly, but I just thought it was too obvious a choice. I asked some others at my centre and quite a few put A as the answer. What do you guys think?

Hmmm
Wat about the cellulose question wat was it ?
The choices were coils into double helix has hydrogen bonds and is insoluble
Thts all tht i remember.

Lipid bilayer was so confusing :/

It was the option with hydrogen bonds, I think.

I did but i guess its wrong everyone in my centre got D

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