Got the paper, if anyone needs a question then just ask.

do you think you could PM me with it (or email it to me @ jsmith613@ymail.com)
thanks

can anyone estimate the whole mark scheme yet?

out of interest did the sand-dune question ask
"How would you investigate the distribution of marram grass along the sand dune" or "... marram grass with time"?

you use a belt transect and place quadrats along it at regular intervals and then look at the percentage cover . . . i then shoved all the stuff about statistical test and reliability and stuff. . haha

Question 6) C) i) what did people put, it was the question where if you increase the flow of the human sewage the concentration of nitrates at point a decreases, but surly if your push the sewage through faster, another limiting factor will mean that not all of the nitrates will be absorbed, so conc should increase ! ?

I put that there is more kinetic energy and so there are more effective collisions of nitrates to the proteins on the root hair cells that are needed for active transport and so the uptake is at a greater rate?

Does anyone have the mark scheme or paper?? I really need it!!!!!!!!!!!!

Use the evidence to explain that:

Harlessness is caused by a recessive allele (2 marks)

That hairlessness is caused by a gene on the X chromosome (1 mark)

Complete the genetic diagram etc.... (4 marks)

What is the answer to the first two?

Heterozygous, mother is a carrier, Etc


Second part was that only males have it. Y chromosome shorter etc

Thanks

Lol is that what you put too?

Anyways, awkwardly discussing this exam when its near results time haha
GOOD LUCK!!!

[jamieward]

Why a belt transect and not random sampling using quadrats?

Will i lose all 2 marks for stating yes and giving a reason for the pig question about reliability of results?

Could you put a link up?

[EffKayy]

Im thinking lower than a C tbh.
