i think were missing 27 marks :O

soo

1)a) Plant protein - animal protein (3)
b) Processes that lead to process B (humus) (2)
c) How the processes C and D contribute to plant growth (reference to nitrifying bacteria).
?) What plant could the farmer use to restore nitrogen the soil? (2)
?) Why rare sheep should be kept in existence (2)
?) The two processes involved in allowing sheep to eat seaweed (2)
?) The two major problems that cause these sheep to be rare? (2?)
?) What are the three stop codons? (1)
?) Why do stop codons stop translation (or some ****)?
?) What are the other 4 amino acids in the chain?
?) Differences between Somatic Cell Therapy and Germline Cell Therapy (2)
?) Differences between PNS and CNS (4)
?) Differences between Prophase 1 and Prophase 2 (2)
?) Describe and explain what happens to the population of waders after hedgehogs are introduced (6)
?) Percentage decrease of Swipes in area 2 (2)
?) Advantages of learned and innate behaviour (11)
?) Describe the process of tissue culture? (7)
?) Describe a suitable method for the student to measure ladybirds up the hill?
?) Explain a more suitable method to list the data collected (frequencies of ladybirds)? (2)
?) The student says, "positive correlation = ladybirds survive better in high altitudes". Is he correct in saying this? (3)
?) Work out p and q (hardy weinberg) (2)
?) Hedgehogs are being trapped and killed. Discuss the ethical implications (3)
?) Explain why nearly all the Elm trees were wiped out when the disease hit (3)
?) Molecular analysis to show they're clones (1)
?) How do Elm trees produce clones [or something] (1)
?) The disease causes the leaves to turn yellow and die. Explain why? (2)
?) How does the leaves dying cause the roots to die? (2?)
?) UUU changed to UUA. What mutation is this? (1)
?) Name of the nucleic acide in 5.2 (2)
?) Define innate behaviour (2)
?) Define learned behaviour (2)
?) Define recessive (1)
?) Suggest and explain (?) two reasons why the hedgehog population increased so much (or something). (4?)

How much is the paper out of? Seems that we have too many marks. :P

What the F** was that. That was my reaction after the exam and everyone elses. Ive been revising like a dog for the past 2 months and it was not worth it at all. There was nothing that you actually, couldve sid, 'ahh i know this. There was ****ing 6 marks on hedgegos, why the hell couldnt they just give 6 marks on electrophoresis. I think we have to do something about this exam,, and i was so peed off, i took a spare copy of the exam and ran off. Looking back on it, only 9 marks on Cellular control and the rest was ecology. Nothing else cept for the behaviour part.
So basically, i have the **** paper in front of me.
Im just angry at how OCR could make a paper such as this to test our biology skills based on 4 units. Errr :/

Any chance you can post it up?

You had to turn them into fractions. There were 346 organisms total. So you'd do XX/346 to turn it into a fraction (or decimal).

No rule was needed, yup.

Don't worry if you thought you waffled through the environment questions - there are no specific answers. They will just use the any valid point thing.

And don't bother starting a petition. It wasn't that hard. Even if you do it will probably be on facebook - clicking, very hardcore activism. Just like when Vanessa George signed a anti child-abuse page on facebook, then turned out to be a serial sexual abuser of toddlers.

It wasnt that bad.

I said that hormone cyokinin could not travel through xylem so the leave begin to age. Also auxin too can't travel to that area. I menioned about Nutrients (But knowing OCR they will probs say rejec that word -.-) can't travel there either.

I wrote about cytokinins too :smile:

I hope it's right!!

for the first question i chatted so much shxt!

i wrote the peptide bonds are hydrolysed into amino acids bla bla

i also wrote about deamination in the liver haha did anyone else?!
