AQA BIOL5 Biology Unit 5 Exam - 22nd June 2011

http://web.aqa.org.uk/UMS/ums_converter_a2.php?id=04

Depends on the grade boundaires. Maximum you can get is 140 UMS. It is out of a 100 marks.

So 80/140 * 100 = 58/100
120/140*100 = 86/100

It totally doesn't work that way.

It converts your mark for whatever paper you did into the UMS

Its pretty simple. You can see that there are two strands from the graph.

One is 64 and the other is 36.

So you want to find two places where when the cuts are made , you'll end of with them strands.

When the L and M cuts are made. You get a 36 strand so the other must me 64 as the total is a hundred. So these two restriction sites are cut.

hey guys! earlier someone posted an amazing document and twas about 33pages of potential synotic and poss essays (i think) but i cant remember what page it was on.. can anyone help me out and know the page number?!?! Massive thanks

I can't remember the page but I have it saved. I can mail it to you?

I will personally buy everyone a drink on here if it does Please AQA...

what kind of topics do you think will come up this year?

Hey I just got a few questions about this paper, and apologize if they've already been asked/answered just don't fancy reading through alot of pages to try and find them :3

• What are predictions out of 100 for A/A* boundaries?
• I got 95 UMS in unit 4, so do I just need 85 UMS in unit 5 for A* or still require 90+?
• Are the answers for specimen paper question 5 a) (i) and (ii) both wrong? As in shouldn't it be Na+ moves into the axon, and K+ moves out?

Thanks in advance

That's DNA Sequencing

Describe the sequence of events leading to the release of acetylcholine and its binding to the postsynaptic membrane.

Yes I get that! But the data on the graph didn't really seem to go

Action potential arrives,and calcium ions enter the synaptic knob. The vesicles fuse with the membrane and acetylcholine diffuses across the synaptic cleft. Then it binds to the receptors.

Is this right?
