AQA BIOL2~3rd June 2013~AS Biology (Now Closed)

Getting iritated by the different interpretations for the 6 marker- Here are the correct marks.

-Active transport
- Lower water potential
-osmosis
- transpiration/evaperation
- Root pressure
- cohesion-tension theory

None of this symplastic/apoplastic rubbish

14

Aha! GET SOME NUTS! -

Same! (With the :3 as well!)
High five!

I put

Reduces number of plant species
Reduced number of habitats
Reduced number of niches
Reduce variety of food source
And because agriculture was in the question
Pesticides kill insect specie

lol anyways can't keep thinking about bio, i've got chem tomo :/ then it's overrrrrr WOOOOP WOOOOP

would i get any marks if i say founder effect is when u colonise a new region and form new founders these individuals from a larger population move to na more isloated area so these individuals from the larger population will have fewer diffrernt alleles less genetic diversity so less able to adapt to the Environment but then i dfidnt talk about americans and amish people so would i get 1 or 2 marks or no marks please someone answer meeee

So you reckon they would allow a range of values for the oxygen 4kPa as I put 17%?

Anyone put that H20 in tracheolies reduces SA for diffusion to take place??..

What's considered a low grade boundary for this exam, what's the lowest grade boundary there's been so far out of 85, and what do you predict for re grade boundaries for this exam?

What did people put for the as well as being female, what two other factors should they keep the same (Or something similar).
I put Age & Species! (Aha)
I was gonna put family/medical history but was like.. they're snakes -_-

Everyone in my college was saying it was horrible but it was alright for me

AQA like to test peoples understatement and their ability to do interpretations, rather than just people's memory...

Good luck everyone.. Will see if I can remember some answers:

I think the snakes liked larger females as they can protect the eggs better and probably are older and mature enough to breed?

A maths question was 16 (diffeence in saturation), there were I think 250 000 Amiths or whatever they are called in USA lol.... The percentage question was somehting like 300 something....

Hierarchy is division of larger groups into smaller ones with no overlap. Phylogenic is the evolutionary relationship between organism based in the common ancestor i think?

The xylem question, I think you had to mention active transport, transpiration and cohesion... Didn't have space to write about root/osmotic pressure.

I wrote all of that as well as the pathways, which I did wrong anyway lol, will they just ignore the pathways stuff and will I still get the marks?
