Good luck with that. Make sure, you dont use your parasympathatic system too much (In times of stress) LOL
genetic stuffs come up loads in the past papers and specimen. its almost certain to come up- damn! but hopefully not as much, what are you guys thinking will come up most? theres only actually ONE question so far on Lac operon, so fingers crossed... hopefully they'll do some good stuff like muscles and the brain and the CNS/PNS. would rather that than sex linkage. arrr!
Thanks ManPowa, I am just a bit confused about drawing and understanding the diagrams just looking through my notes. Do you know of any easy way to understand the different terms and to work out the diagrams?
Also are there any links to some more past papers as can only find a couple on the OCR website.
Thanks!
there are only three past papers in total
the two on here plus a specimen. sucks! so hard to revise with so little practice papers to do. aah well. we're luckier than last year. having to go first with NO practice papers!
Someone explain the selective breeding of bread wheat please! .. Don't understand it at all! In the simpliest way possible please
T.Austivum as resulted from the hybridisation between members of different species. Chances of doubling the chromosome number (polyploidy) restores fertility in sterile hybrids and this allows the chromosome number to significantly increase to 42 chromosomes. Thats it really.
