How did your Biology Paper 12 go?

[roxylara]

i

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

I too chose D

 

[roxylara]

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

Same here. It was the option that went along the lines that it stimulates haemoglobin to dissociate its oxygen more quickly right? Because if it is then yes I did that one Aswell

 

[roxylara]

YESSS =)

Was B the one In the left hand side down corner?

 

[Snowysangel]

It was D. The organism that everything else except plants was pointing toward. Decomposes break down nutriebts which plants take up so the arrow was pointing from that organism to the plants

 

[Snowysangel]

And it was antigens, receptors and allows fat soluble substances to pass through.. Both glycoproteins and glycolipids act as both antigens and receptors

 

[sumeru]

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?

I chose A for that one....

 

[sumeru]

Same here. It was the option that went along the lines that it stimulates haemoglobin to dissociate its oxygen more quickly right? Because if it is then yes I did that one Aswell

C was the correct for that one...it said that dissociation increases with increase in co2 conc..or something like this...

 

[sumeru]

What was the fluorescent & plasmodium one? I picked D in both because they made more sense to me

Same here...D is the correct one...

 

[sumeru]

I chose D for the membrane one too.. Don't remember what was the option for plasmodium.. Anywho what did u all choose for the thing which directly effects Surface Area.. I chose emphysema and smoking

Yes i too chose that....only emphysema and smoking decrease the surface area for diffusion

 

[aneeq247]

Yeah I chose A for the tar question too. And yes your answer to the enzyme question is also correct.

 

[aneeq247]

Yes i too chose that....only emphysema and smoking decrease the surface area for diffusion

I dont think smoking directly affects surface area, i chose emphysema and the other option.

 

[aneeq247]

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

I chose A because the affinity for oxygen of haemoglobin increases in areas of greater co2 conc. haemoglobin will lose oxygen more readily.

 

[Princess Raven]

What did u guys chose for the b and t lymphocyte question

 

[Fallen316]

C was the correct for that one...it said that dissociation increases with increase in co2 conc..or something like this...

same here.

 

[zem]

That was A for sure they all have 70s ribosomes

Yeah thats what i chose aswell

 

[zem]

What did u guys chose for the b and t lymphocyte question

I dont remember that question very well could you please elaborate it a bit?

 

[Princess Raven]

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

Yea I chose that too

 

[Princess Raven]

I dont remember that question very well could you please elaborate it a bit?

I'm not sure but it was something like which one related to t and b lymphocytes is not correct

 

[maryam fatima]

that atherosclerosis question? i did "nicotine only"
and ht directly reduces surface area? i did " emphysema and lung cancer" :/

 

[maryam fatima]

I'm not sure but it was something like which one related to t and b lymphocytes is not correct

A i guess...
