hey guys, im done with biology paper2 variant 1
DEAD DEAD DEAD DEAD DEAD EASY,
but what was the answer for the mag. question, i put 29 micrometer right?
and for the emphysema question?
-
i think it is a rule to wait for 24 hours so just delete your post so that you don't get into trouble with the mods
-
No i think everyone's done with it, 24 hours is just in case, but im sure everyone is done
-
Everyone is done..but 24 hours didnt pass yet!!
please dont discuss anything now or will face banning!!!
Please follow the rules!!!
-
Thanks AS girl :) .. guys please just follow the rules, they're nice and simple, last year you faced banning, this year you'll face CIE themselves!
and the 24 hour rule is from CIE, check their rules .. thanks for your co-operation! ;)
-
Sorry, i just can't wait.
AND NO! I WOULD LIKE NOT TO FACE CIE! LOOL :p

Nice proxy you're hiding behind, "Spy".

Nice proxy you're hiding behind, "Spy".
noboby really cares mani!!!

the exam was pretty easy except for one tricky q! ;D

-
the exam was pretty easy !!
though i did some really STUPID mistakes...
thats the thing with easy exams .. they are easy but u do stupid mistakes... hard exams u answer perfectly... :P
what do you guys think the curve will be like ?? im thinking 48 for an A ??
-
this was such a baaaaaaaaaaaaaaad test
because it was sooooooooo dead easy, now the grade boundaries are gunna shoot up meaning its quite hard to get an A
-
hows cums no one is discussing the ppr? 24hrs done ryt?
emphysema qn anyone?
-
Apparently, in AS, threshold values only differ by 1 or 2 marks.
So if you had an easy exam, you should be very happy, cuz you've scored higher.
Although I've heard this Math only, I reckon it applies to all AS.
-
is 24 hours up?
-
is 24 hours up?
nope, still about 1 hr and 16 min!!
-
guys no one is doing the exam in this time, thats it everybody's done, and an hour is not a difference
i say we start discussingggg pleasee (A)

if we get caught its ur fault :P ;D
the micrometer question i guess it was 29 um or somethin like that!
-

the micrometer question i guess it was 29 um or somethin like that!
haha umm okay :P
yeah 29 :D
and the emphysema?
-
haha umm okay :P
yeah 29 :D
and the emphysema?
first part was
1) damaged elastin fibres
2) swelling of alveoli
the symptones:
1) excessive coughing
2) wheezing while breathing
thats wat i wrote but im sure there are more answers!
-
anyone around who sat for bio cie ppr 5?

yeah i sat the paper, pretty retarded paper

i wrote for the first part
damaged elastin fibres
loss of surface area to volume ratio due to loss of alveoli
and the symptoms
person has to breath forcefully,, like he has to actually think about breathig and do it with intention
and higher breath rate to make up for the decrease in oxygen intake
you think thats right?

theyre probabely right but we gotta worry about the other questions which were for 4 and 5 marks :S

theyre probabely right but we gotta worry about the other questions which were for 4 and 5 marks :S
for the tubercolosis and malaria question i wrote that since malaria is transmitted through a mosquito then in tropical regions it would survive best due to suitable conditions but not anywhere else where as tubercolosis was only transmitted through droplets in the air and therefore required nothing more than an overcrowded are for its widespread and since the world is overpopulated these days, then its widely spread. furthermore, vaccines mayhave proved more effecient against malaria. and finally that symptomless carriers can have the disease of tubercolosis and pass it on to other people with noticing, and there for not differntiating between carriers and uninfected people.
and for the vaccine question
i said that the vaccine contains an active but diseaseless form of the pathogen where the disease causing part is removed ( usually DNA or RNA) and that the protein coat is left so that the body recognises it and therfore creates memory cells for it so that as soon as the actual pathogen attacks again it is eliminated quickly before causing illness. i also said that mothers having a fetus in their wombs pass on these antibodies, meaning any antibodies the mom has made will be passed to the fetus and any diseases she encountered, the fetus will be completely immune against them and therefore generation after generation the disease will be completely eradicated
:D
-
i think that u shouldve mentioned the anopheles female mosquito is the only type that can act as a vector for the plasmodium, and that these mosquitos grow in puddles of water which is usually found more in tropical areas than the rest of the world
-
i said that but vaguely :)
i said tropical and that stuff, i hope i just loose a mark :)
yo what was the answer to the last question?
prove amino acids to the plant for protein synthesis right?
-
and what about why water is needed in plants?
and the rhizobium question? (i cant recall the qn)
also what are the alveoli addaptations?
-
PROVIDE*
@alayna: i wrote: 1. as a solvent for transporting assimilates
2. prevent from over heating by transpiration
you can also write that it helps in turgidity or in photosynthesis :)
rhizobium provides plans with amino acids for its protein synthesis
and the alveoli adaptations i wrote, that it has a very high surface area to volume ration meaning max. diffusion
2. it has very thin walls meaning two things, one that diffusion can be very quick, and that its very close to red blood cell reducing distance for diffusion meaning its also a fast process. i also said aveoli cells may have few organelles to allow max space for air and therefore max. oxygen
:)

for the water question..creating hydrostatic pressure..does it make sence? :P
-

yep :D

why do u discuss the exam...i see no point!! what u did is now done..rather than worrying about this,you should concentrate on ur other exams!! dont i have a point?? ;)

lol thanks Spy! :D

anyone around who sat for bio cie ppr 5?
Yeah, I sat p5. :/
BULL - A - SHEEET. I don't like ittt.
-
have u guys been discussing variant 21 wat abt 22..........
-
Yeah, I sat p5. :/
BULL - A - SHEEET. I don't like ittt.
it wasnt that bad!!
-
wat about the question tht says bothh ventricles and atria were relaxing
WAS IT 2 OR 7 ???
-
cmon ppl plzz im dieng to know the answer!!

77777777777777777777777777777777777777777777777777 :P
thats what i wrote in the table, 1 3 5 7 im sure of the first two and i think the third is right i just dont know about the second, but anyways i think more than one answer was possible
-
bio p52 was bad! p22 was better
we jus had 2 questions for p5! :S
-
bio p52 was bad! p22 was better

my paper 21 was really good
but paper 51 was alright!! hope i did good in it :S
wat questions were in ur paper 5?
-
1st qs was of potometer (mesophyte & xerophyte....rate of transpiration...)
2nd qs was...of number of cells increased by some amino acid in a culture! smthing of this sort!
-

ur luckyyy!!! these questions are kinda easy
ours was messed up
1st question was about "leaves floating in a solution when they carry out photosynthesis" :S it was really hard
2nd question was about antibiotics in agar jelly, i first thought it was easy but then it turned ot to be the most messed up question anyone could get!!!
anyways whats done is done!!!
-
What shape do you think the graph was for the transpiration question (ppr 52)?
-
@unknown 101 yeah bt it was like weird! :P now we can jus pray! hope all of us do well in the rest of the papers! iA
@ Aminah...well the rate of transpiration for mesophytes is greater than xerophytes...so it'll be steeper for mesophytes... hope u understood! :P
-
Hmph. True. iA we'll do well. :)
-
paper 2 variant 1 was leaked.
And CIE isn't doing anything about it.
I hope they don't leak Paper 3, I don't want to see people drawing their observation tables and writing the results before doing the experiment itself.
If you're taking p3 variant 1, pm me.
-
what about the questoin what is mean by globular.. or something like that ??
i wrote it has a specific shape... carries out metabolic functions.. is tht correct ??
also the question why is it important that enzymes check for error in DNA
i wrote to prevent mutation... and so tht the DNA can function properly
wt do u think ??

Implying you continue talking to a member of staff like this, I'll ban you.
Implying you continue doing this, I'll still ban you.
Implying you create a new account, I'll personally still ban you.
Implying you're a good boy, you'd stop being disrespectful and obey our rules.
Implying you don't like our rules, GTFO!
Understood? ;)

Well, I can see that you fail to comprehend the minutiae of the English language especially since by implication you are being quite explicit about your apparently belligerent nature.
In short : This is your final warning ! One more post that disparages another staff member and you will be served a ban

one was written by a normal human being, and one was written by a *censored* wit
.. don't judge me :P
-
ooooooooook
ignoring all of the above
i wud like to ask a question
in the sample paper for biology w2 paper
they ask about measuring the yield of coconuts wat do we do for dat??
do we count the number of coconuts or measure the mass of coconuts?

If I am lifeless
Glad you used IF, because I amn't. Sadly, I don't have the time to sit here all day getting banned by mods who don't know even the basics of IT.
I will be announcing a new forum soon for anyone who's taking GCSEs or IGCSEs. It's will be
-Fa**ot-free
-retard-free
-modded by professionals (me)
-Underground forums for elite members
Everyone's welcome to join (Except q8 and Xam, I will ban you on sight with my type of ban). I will be announcing it on a variety of sites when it's ready for launch.

haha lol i know wat u mean i asked a question loong timee ago but no one has replied till now
lol well globular is the 3d shape of the enzyme formed by the folding of the secondary structure of proteins.it is wat gives rise to the shape of the active site of the enzyme
-
mine was ok... nt so good... it was mostly general...
hiv ques??? that antibodies 1???
mine waz not gud either....simplest questions were asked and i prepared for da toughest ones...:(
yeh da antibodies...for tht i rote da whole immune system story where at de end thy r destroyed by HIV virus...wat did u ryt?

haha wt cn we do :P
anyways, during the exam, i dont know why i didnt write the 3d shape.. even though i thought about it :S
so wont i get a mark so the specific shape thingy :P
nd wt did you write for the importance of enzymes correcting the DNA ??
-
mine waz not gud either....simplest questions were asked and i prepared for da toughest ones...:(

ya me 2...
that first macrophage attacks it n cut the surface for antigen... thn T lympho recognize it n signals b-lmpho to produce antibodies... B lympho thn divide to form Plasma cells n Memory Cells n thn produce antibodies... like that..

haha... yea cie :P
no worries.. they r all the same .. bio is bio whatever board ur examined :P
-
i just rote brieflt tho...nt in detail....
and i asked my teacher she said tht it waz a tricky question and we had to rite abt da immune system-how it wrks whn an infection happens and how it is thn taken over by da virus...

uffff i missed the fight that happened here!! seems funny :P

GO THROUGH THE PAST PAPERS AND REVISE THE DRAWINGS THAT U TOOK AND BE CONFIDENT CUS HE TELLS U ALL WAT U NEED TO KNOW REVISE JUST REVISE THESE STUFF AND U WILL BE OKAY AND IF U HAVE ANY QUESTION U MORE THAN WELCOME TO ASK AT ANY TIME :) :) :)
GOOD LUCK TOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO ALL OF U

for those who did BIO VARIANT 2 (ppr two)
wt did u guys write for 'how does antibodies come into action' or sumthin like dat
it was the HIV question last part
-Thanks :)
-
wasnt it about immune response. pathogens enters, primary response, specific B cells clone, production of plasma cells, production of antibodies n blah blah..................
-
for all who took the bio variant 1
what did you guys write for the question that asked why is it important for the enzymes to check for errors in DNA ??
i wrote to prevent mutation and allow DNA to function properly..
wt do u think r they correct..??
and for the vacince question
i explained how B lymphocytes function .. yea ??
-
is it ok to discuss p3 ???
