Haha yup! I had that as my answer. Anyway, do you remember the hereditary chart? I remember the first two parents P and Q were blood type A and B, children one AB, one O and the other was what? And which person were they talking about for the possibilities?
Not sure but I think...
A X B
offsprings : O AB A
A X with an unknown S
produce offspring of phenotype B
so S must have I^B allele

Damn, missed out I^A I^B. Anyway I remember person S was of blood type AB and they asked why person S cannot produce a child of blood type O :)
i thought person s bloodtype was unknown?
Person S has bloodtype AB....right? omg dont tell me i saw the wrong thing.
not sure, maybe my genetic diagram wrong cos i cant rmr. BUT i can cfm that they say someone has bloodtype AB so cant have offspring of O

I'm positive. Don't worry ;)

Have you read those posts where I found my mistakes??? How'd you know I'm a girl anyway, I can tell you're a girl too :P
har you are a girl?

Girls can usually identify each other easily :) This is so off-topic. HAHA.
lol girls say 'man' too eh.

Hahaha! Cuz' i'm a very 'man' girl? LOL I'm macho yo.
i tink i can spot a girl liao.
1) say haha alot
2) like to put smiley at the back
3) like to act manly.

hmm will 'respiration' alone do?

Guys are the exact opposite, they're like emotionless (online)!

Not sure, but since they already hinted you a few pages later that you'll write anaerobic respiration, it's safer to write aerobic respiration. Since anaerobic respiration actually takes place in cytoplasm of cells, not the mitochonDRION (you are penalised if you wrote mitochonDRIA)

Because there's no need to be so "into" the web life. Not that I mean anything offensive, but we lead a real life outside the web. I do use smileys sometimes, to lighten the mood of my post, esp when I am posting something solemn. I have no idea why girls dig smileys (how do you spell) so much. Some of my girl-friends even insist that I use smileys when I talk to them on MSN.

All doubtful people, just listen to this advice. Because I'm confident too. We are too pumped with adrenaline to be cock eyed in the exam hall.
great, luckily i wrote mitochonDRION not DRIA

I wrote mitochondria -________- No marks at all?
Haha yeah I know. Guess we're more expressive and I totally understand how your girl friends feel HAHA because a smiley-less conversation (to me) can come across as cold/distant!
Anyway did anyone do the Either question for essay?
I didn't do Either, but I think I can still answer them if I want. Any questions?

Confirming my answers :)
Can't remember the exact question but it's along the lines of,
(a) "In extremely cold conditions, the cells in fingers and toes die. This is frostbite. Explain why wearing thick gloves, socks and shoes does not prevent frostbite." [5]
I wrote that the constriction of arterioles and dilation of shunt vessels prevents the flow of blood to the capillaries in the skin, thereby cutting off blood supply to the skin. Fingers and toes contain capillaries. When the blood supply is cut off for too long, the cells in fingers and toes do not receive oxygen for respiration or nutrients vital for survival, and the cells will eventually die. This is frostbite. Thick gloves, socks and shoes only prevent heat loss through radiation or convection, and do not prevent the cutting off of blood supply to the skin. (I also added in redundant parts about the sweat production decreasing and metabolic rate increasing to lengthen my answer)
(b) "In cold conditions, shivering takes place. Explain why this happens." [3]
When production of sweat is decreased, metabolic rate is increased and blood flow to the skin is stopped is not sufficient to reduce heat loss and increase body temperature back to normal, this stimulates us to shiver. Movements in the muscles warm the body up.
(c) "Explain how the mechanics for control of body temperature are synchronised." [2]
They are synchronised by homeostasis. When the hypothalamus detects the body temperature rising above or falling to below average, the brain sends signals to various body parts to work to increase or decrease body temperature, depending on if the body temperature is below or above normal.
Something like that.
err... if i wrote the process of mitochondrion is to 'produce energy in the form of ATP' izzit correct???
