HECK TO THE NO, i mispelt lichen T__T
not sure what happened there
Was I the only one who put Zebra Fish for the indicator species?
It's from a past paper however, I think it was Genetically Modified... Probably actually a made up fish.
Please be more of us! I want to start a Zebra Fish colony. Haha

That isn't allowed

Lets create the unofficial mark scheme for today's biology paper, please help by commenting in this format: [Question number - Question - Answer - marks given].

Please continue to submit answers!

for question 29, i'm sure to get the final mark u have to say ' in the early stages of development '.

heyy, are you sure its Lichens? Apparently they asked for an animal..im not sure


I don't remember it asking for animal specifically.. Probably because I did that question in the last minute. :tongue:
But if it was asking for animals, probably the mayfly larvae - used to detect levels of water pollution.

I put that as well, but apparently the question specified about a living indicator that was an animal - meaning bloodworms or another living animal indicator...


Apparently so. I don't remember reading that part.. You'd probably would have had to put something like mayfly larvae - used to detect changes in water pollution levels

Independent company would be unaffiliated with the drug company

Legal, recreational



Boys drink more beer, lager, cider than girls, girls drink more of everything else

It's too small a sample size

Fat - store of energy and warmth
Carbs/sugars - used for energy through respiration
Proteins - growth, repair of cells, replacement of old ones
Fibre - used to aid digestion

Skin is sense organ for spinal cord

80/50 = 1.6 for neurone speed





That's jumbled up - what did ya get for the horses one


4 toe bones > 1 long and thicker hoof.
thinner and smaller ankle + foot bone > taller, higher up and thicker

(few more)
literally the variation question was.

< variation through mutation when the mud dried in few of the horses,
< this variation caused competition between the "original horse (forgot name ;d)" and the new varied offspring
< survival of the fittest, the ones who had this variation were able to survive and the ones who did not have this variation would be killed, eaten ect. (many reasons)
<the ones who could successfully breed would pass their genes (the varied gene) down to its offspring, (if you have a 5 mark question for this say that a new sub-species is created.

mate don't be mad that you are intellectually inept.. You should have revised harder rather than cramming the night before.

You can make an official complaint to aqa tel; 0800 1977162 speak to customer services and ask them to email confirmation back to you. They are investing this paper and the more complaints
the more they will have to do sort this mess out ! Get dialling

Do you think they will accept: the sun makes the snails' shells get lighter instead of the camouflage in the woodland?
And do you think that if I wrote an independent company is one that doesnt rely on anything else to function, would that be right?
Thanks
What do you think you'll get?

I wrote this shell colour keeps predators away.

The indicator species answer was lichens and the environmental factor was air pollution

GM Mosquito - enzymes used to take out gene (first mark) the gene is transferred to the mosquito (second mark) at an early stage of development (third mark)

Scatter graph used to show the negative correlation


Are you sure it didn't say indicator animal? I put lichen, but some people told me it had to be an animal.

That was the most hardest Biology exam I'd ever doneeee!!!!


I don't think that it was Hard but I think that it was more overly wordy and confusing... that and the fact that it wasn't even biology related for most of the exam :frown:

You know for the alcoholic girls and boys question.

I wrote girls consumed more alcohol than boys.. Because i counted them up is that still right?

I wrote about Zebra Fish too, from June 2012! It's the only thing I could remember xD
