I don't know but if 85 then can secure a1 already sia, but mcq i think might throw some tricky Q, must be careful
The first answer for genotpye is I^AI^O or I^BI^O?
I^A I^O
got one qns they ask protect the body, prevent the entry of bacteria
if i put lymphocytes and phagocytes will they give me one mark?

I think so. Since they're both WBCs.
Thanks for your comments of my mistakes. Feel abit better. Yeah for the proteins i put all seperate .
is the second one BB or BO

They asked for possibilities. I put both, both are possible :)
ok so it is BB or BO. Cool. And i was bothered by if the letter is sub script or super script. So that one minus 2 marks cos i wrote sub script. Gosh shouldnt have doubted myself. I changed it last min.

Yup, it is! But I'm not sure if they'll only give marks if you write ALL the possibilities, which are both. Did you? It's okay, I always doubt myself and regret it. Like the substance which is present at A, B, C, D and E, I put carbon dioxide, then cancelled and put urea, then cancelled and put carbon dioxide, then cancelled and put urea... I cancelled a total of 4 times and ended up with carbon dioxide which I'm hoping will be accepted because it's a metabolic waste product and urine formation is under Excretion... :P
I actually put mineral salts... do you think it'll be accepted?
carbonated urine. lol jking. I think they may be marking strictly since the paper is relatively easy.

I think so! Some salts are reabsorbed but excess salts pass out with urine as well. I think I'm wrong for putting carbon dioxide, oh well haha. Couldn't think of anything else O_O

I just Googled it and found out there is carbon dioxide in urine so I'm still hoping :(
I think carbon dioxide is alright y'know! don't worry (; and and anw, what did you put for the two substances that can be found in A but not in B ? haha.
protein, red blood cell?
Omg i put proteins & fats.
because I thought RBC will be present in the bowman's capsule, no? Just that RBC can't pass through the glomerulus... sighz.
I am not sure man. I think RBD cant pass thru the capillaries right?
err... RBC how to pass through capillaries
haiz.. i never study for that chapter.. the metabolic waste i put urea and creatinineT_T
I put protein and cellulose..
Is cellulose accepted?
I put red blood cells and fat molecules :)
i put mineral salts for the kidney Q (excess are not reabsorbed)
RBC can pass through capillaries by changing their shapes to bell-shaped
Hence, I put protein and RBC (too big to filter out, components of blood)
the possible genotypes are I^B I^O, I^B I^B, I^A I^B

Salts (namely sodium ions) are reabsorbed. I think they were talking about if RBCs can pass through walls of capillaries haha.
haha ps, cant too big to pass through.
