The last question about indicator organisms, I put stonefly nymph which lives in high level dissolved oxygen and for similar I put invertebrate animals? What about everyone else?

I have no idea! I think it was just information- it wasn't actually a question

oh ok, thx. I was worried I'd missed a page out!

What does the definition of an "independent company" have to do with Biology? Honestly, that biology exam was the worst. Defence against diseases, menstrual cycle, plant hormones and a bunch of other stuff I revised for didn't come up :angry:

I'm hoping to have gotten a B, maybe high C. I looked at the unofficial mark scheme and I've got around 26/27 marks so far (but I know it's not accurate, just a rough idea)

Would this be correct if I put 'A company which tests the drug and puts it through different clinical trials' for the 'What is an independent company?' question.

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

For the six marker:
Ther are seven food groups: carbs, fats, protein, minerals, vitamins, fibre and water.
One was already given (minerals) so id presume the 6 left would be one for each mark - name and explanation.

Carbs - provide energy
Fats - store energy, insulate us, protect vital organs
Protein - build and repair tissues such as bones and muscle
Vitamins - general health
Fibre - regular bowel movement
Water - maintain fluid level, regulate body temperature

Yes those GBs are totally u realistic. I personally feel the grade boundaries should be slightly lower this year compared to last year so should be around 45 for an A*
