differences between humoral and cell-mediated?

what was the valve question, is it just there to ensure one way flow?

what cells are found in lymph nodes for innate immunity (macrophages?) and adaptive (plasma B cells?)

also was it 8 or 7 amino acids coded i cant remember im having bad thoughts about this

8 amino acids and natural killer cells maybe??

Rest assured I'm pretty much certain (99.9% sure) it was 8.

Likewise. 8 Amino Acids.

Cant remember what i wrote for differences but i remember writing macrophages for innate and for adaptive the question mentioned an established rough endoplasmic reticulum so i wrote about plasma cells, the exam has been scanned so ill check it now

Edit, yep its 8

What SS are people hoping for, realistically?

Before the exam I was thinking definitely 42+, but after that hellish exam I'll be happy with even a 30
I think the easy psych exam the day before made me too relaxed about exams haha

[Sine]

first 10 SA questions I thought I did really well maybe lost a few marks but the last one was horrendous.

whats the thought on A+ cut-offs and 45 cut-offs (rank 1)

Maybe like 96/110

[Gromekk]

No idea, I did a bit better on this compared to the 2014/2013 ones on my first go, but that might be because of getting better at this stuff, most people seem to think itll be pretty low

for a 45?

I actually think I did pretty well except for the last 5 marks and the 2 marks question for comparing the sediment(didn't really have enough info for 2 marks)

In a hard exam then yes. Maybe a little higher like 99/110

Had a look at the exam. Wow that paper was hard - I'm pegging a cutoff of about 86-90/110.

About the last question - I think the evidence showed that humans originated in Africa. If early H. sapiens originated in say Asia - then they'd have been mating with Neanderthals. At some point, they would have migrated to Africa - with the Neanderthal DNA in them. However, since present day Africans do not have Neanderthal DNA, there's a contradiction.

If humans originated in Africa, then some would migrate and mate with Neanderthals elsewhere, but the ones in Africa remain in Africa, never mate with Neanderthals, and therefore have no Neanderthal DNA.

Yeah, about the Out of Africa question, this was basically my line of thinking. Except for the fact that I didn't write my answer correctly.What really confused me was the fact that the Out of Africa hypothesis states that homo spaiens displaced other homonin  species without interbreeding, so I ended up writing a contradictory answer. :/

Confused, how is it 8 amino acids?
Wasn't there a start codon (TAC), 7 amino acids and then a stop codon (ATT)

No amino acid for stop codon!!!
