WHAT DID YOU GUYS THINK
No enzymes
6 marker on transects and qudrats
Lots of graphs
????
THOUGHTS

[Lovely95]

I had done it in the morning but I did know how to write...it sucked that enzymes were not tested..

Can anyone give an unofficial mark scheme for the new specification exam?

[John Proctor]

agreed ^

[John Proctor]

question 1b, with what variables were hard to control.....this is no joke i wrote, 'metabolism or atheletes..and time atheletes sleep for.."

please can someone tell me the right answer.

[iCamification]

I had absolutely no clue for that one either I kinda guessed:
The amount of glycogen their muscles store
And the amount of exercise they do outside of training but i dunnna
What did you guys put for the transect/quadrat one?
AND MARK SCHEME ANYONE...

[cfcforever]

mark scheme needed!!!! what did you put for the onion cell question about sexual reproduction, i wasnt sure, i thought onion cells reproduce asexually so i just put the gametes fuse and half the chromosomes come from the mother and the other half from the father meaning its dna is unique, (im not sure onion cells do sexual reproduction so i just put what i know) what did you guys put?

[Arusa123]

i failed this test soo miserably, i would actually be happy with like a B, not really expecting anything higher tbh, ahh that was soo bad

im not sure if it is right but i put the amount of glycogen stored in the muslce, and the size of the athletes muscle.

omg yeh, what even was that question!?!?? i wrote some stuff about chromosomes inherited from 2 parents so means variation...

I'm kind of annoyed, for the question where you could use a calculator to work it out (The cells and their sizes), my calculator wasn't working, so I told a teacher and she took it away. I waited for like a minute expecting her to be finding a calculator, but she never came back, so I moved on. When I looked back, I realised it was easily doable in my head, so I did it and got 200 (That's right isn't it? ) That small amount of wasted time meant I couldn't finish the 6 mark quadrat question that much at all, as it confused me for a while as it is.
I think it went well other than that though

that question was retarded unless onion root cells have sex it makes no sense but anyway i put a answer down if it is right we shall see do you know when the results will be given out?....

What did you guys write about the birds being isolated from the island and why they could not interbreed(4 Marks)?

sneaky bit of speciation... (Y)

[jellybeanjosh]

Did you explain all four 4 factors of speciation, or give possible reasons, such as an earthquake etc?

[dontalha]

i think this test went quite well if not excellant hopefully the grade boundries will be low as everyone was complaining that it was again all to do with how science works and not real biology to it, there was 2 six markers and couple of two and three markers. the second six marker was really good for me as it had already some up in the specimen paper and i actually revised the whole thing on it which was to do with speciation.

[dontalha]

the grade boundries will be like 41 or 42 out of sixty for an A* as it was like that in the specimen paper and the specimen paper was slightly easier. around 37 for an A and probably like 30 for a B
