Post by: [Spy] on May 14, 2010, 07:11:59 pm
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?

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! ;)

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.

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!

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


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

Post by: unknown 101 on May 15, 2010, 01:12:03 pm
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

Title: Re: Biology
Post by: [Spy] on May 15, 2010, 01:15:34 pm
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?
Title: Re: Biology
Post by: Alayna on May 15, 2010, 01:16:58 pm
and what about why water is needed in plants?

and the rhizobium question? (i cant recall the qn)

also what are the alveoli addaptations?

@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

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!!!

@ Aminah...well the rate of transpiration for mesophytes is greater than xerophytes...so it'll be steeper for mesophytes... hope u understood! :P

also the question why is it important that enzymes check for error in DNA

You lucky f**k, at least your exam didn't get leaked.

Her next exam is on day 18 of this month, the practical test, HOPE THAT ONE DOESN'T GET LEAKED TOO.

wow ... i never knew tht this site was made for u guys to fight  :o
anyways, i asked u guys a question.. but it seems tht fighting is more important over here....

anyways, my questons again :

 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 ??
