Biology P11 , HOW WAS IT?

[Chris_gangsta]

i did paper 13 for as that's the variant in new zealand..i'll probably get about 38/40 but i am the freakin man at bio though.. i hope a2 will be as good in november..

lol the memory cells question was only b-lymphocytes and t-lymphocytes ;P

ah i got that wrong......
and that graph one i picked C too,but i thought D is the answer?

Okay, I'm seeing a lot of confusion over here, so I'll try to clarify a few things:
1) Fatty acids AND glucose BOTH have C=O bonds (Fatty acids are carboxylic acids and the STRUCTURAL formula of glucose has C=O). Glycerol is propan-1,2,3-triol, so that's 3 -OH groups, but no C=O groups.
2) T-lymphocytes and B-lymphocytes BOTH produce memory cells
3) The answer to the question with 120 nucleotides was A (20 amino acids). This is because DNA is double stranded, so only half the nucleotides (60) are used to code for a protein. An amino acid is coded for by a codon, which contains 3 nucleotides, so 60/3 = 20 amino acids are coded in total.
4) The glycoprotein was responsible for the hormone recognition
5) The answer to question 39 was C, I think. I really can't remember which one it was, but it started with the last row, followed by the first, second, then third. You must multiply the number of individuals by the biomass of one individual (first two columns) then arrange the values in order
6) The answer to the net productivity was 0.75/1.8

cell membrane diagram and the question was about which part is responsible for the hormone recognition ... i picked B which was glycoprotein

i picked d one wid the protein channel cuz i thot dat had a specific shape for d hormones ???

hmmm actually when i saw the word recognition i directly picked glycoprotein which was "B"

what's the answer for the question which asked about what's the sequence for the substances that has high affinity to haemoglobin (CO2,O2,CO) ???

what's the answer for the question which asked about what's the sequence for the substances that has high affinity to haemoglobin (CO2,O2,CO) ???

i wrote CO ----> CO2 ----> O2
not sure if it's right though :/

i chose co then o2 then co2 :/

yea bu i got confused even tho i workd that same ques in past papers like thrice thot d hydrocarbon chain was something separate from d protin ahh.ok bu thanx for ur reply

same here

What was the answer for carbon 6 and carbon 3? something like that. I chose active transport for 6 and diffusion for 3? what u guys wrote?

ur answer is correct

 

[yazan1995]

what will be the starting of A ? though many said it was easy but i feel it was tricky and i don't feel the threshold will be very high . i guess 31 like June 2011

 

[yazan1995]

what's the answer for this question?

 

[The King XII]

what's the answer for this question?

A.

 

[The King XII]

A.

I meant B. sorry

Thank you buddy
