Higher Human Biology 2013

Like people have said .... There was hardly any ACTUAL human biology!

I said Demography...

It is demography

Do you know the answer to the one about the % of Y chromosomes in the Sperm mother cell and the Mature Sperm Cell?

I got 100% for mother sperm cell and 50% for sperm cells and dammit :/ ah well that's 1 mark down the drain

That's what I got, My biology teacher said it was a weridly worded question and she wasn't sure if that would be accepted but I'm sure it's right (hopefully) what about the question on antibodies, why the concentration decreased when the mass was the same?

I really did not have any clue on what the answer was for why the mass decreased :/ what did you write ??

What about that multiple choice question about Nicotine crossing the placenta and how many weeks it affected the ferus or something. I put 9 weeks, but i litteraly guessed because non of my calculations were one of the choices, haha.

Yeah, I'm sure I had nine. A question like that was our first prelim a lot of the questions have came up in previous papers, just worded differently. My biology teacher noticed that too a lot had came up before.

Ah ok!

And the graph question, did anbody else do phosphate up one sode and nitrate the other then shaded the phosphate bars in and put a key? no idea why i did that, hmmmm

I'm so glad you've said about your first essay because that's exactly what I wrote! did you say anything about rbcs?
and the baby has a larger sa:vol ratio so loses heat more quickly and the elderly persons temperature regulating mechanisms are not very effective, sound about right?

do you think if I wrote about the hypothalmus and the mylen sheath being damaged or not as good as it was before for the gran will get any marks. I also wrote for the baby that he hadn't gone through mylenation and that he couldnt do things for himself, like put on a jumper

Seeing as nobody else has posted multiple choice answers this is what I got (I wrote them down on rough working paper) but I honestly have no idea if it is at all reliable...
How does this compare with other people's answers?

I said that the woman produced increased milk on the 3rd day so the concentration of antibodies decreased. I hope I'm right... There was too much unit 3 I think, it wasn't a fair split. How do you think you've done?
