So I was doing the 2009 written exam 1, and came across a question involving accessory pigments.

As far as I was told, aside from chlorophyll a and b, apparently we didn't need to know about the different pigments such as carotene, xanthopyll etc. and that it'd be explained in the question..except it wasn't in this case.

So I guess my question is, to what detail do we need to know about accessory pigments?

Thanks :)

Are all those in the genus Homo referred to as 'humans' whilst the term 'modern humans' refers specifically to Homo Sapiens?

that accessory pigments absorb different wavelengths of light - that's all

yes, but it could possibly change on the context it is used in

Yeah thought so, was just making sure. The last thing anyone wants, is to be presented with something that you thought you didn't need to know, in the exam haha! Anyhow, thanks :))

Humans refers exclusively to Homo sapiens. Those H.sapiens that arose in Africa initially would be very distinct from those that survive now. Modern humans are those humans which, anatomically, represent the same anatomy of those that survive right now.

When you write your answers, and if you write more than the lines given, the examiner will still assess what you've written, yeh?

Can someone please explain question 7 (a) from the Unit 3 2003 exam? Why wouldn't the rhesus antibody be present prior to the operation?

Thanks :)

At that time, the man hasn't exposed to the the Rhesus positive blood group and hence no antibody should present in the body. Until he get a blood transfusion that the immune system starts to kick in.

That's okay but don't write out side the bordered box where it says "writing not allowed" or something

Was doing a NEAP trial paper and I came across this question... lost all four marks on it. I simply can't understand what each reaction is and I have never seen a diagram like this... is this similar to what VCAA would provide? Also could someone explain the answers?
