OCR Biology A Exam Thread (Breadth - May 26, 2016 and Depth - June 7, 2016)

How did y'all do the maths question for guanine to get your answer. I did 100%-(the value given) and then divided by three (for the other three bases). Was that right?

Tell me about it. I revised so so hard but my answers are completely different :/

Cmon! Be optimistic, it was such an easy test I had so much time at the end and I didn't get stuck one bit! Also, did you actually revise so so hard or did you just cram the day before? hmmm :rolleyes:

At the start of the book there should some small print that says that not everything is covered in their books

I did 22x2 which was 44 and then 100-44 which was 56 and then divided that by 2 to get 28%

No they said there was 22% of adenine meaning there is 22% of thymine.

Therefore c and g = 56/2 = 28%

The question about the conservation when asking about small groups were isolated advantages where:
if a disease arise will not wipe out whole population
isolated therefore protected from predators and human hunted rhinos.

Advantages????????????????/ Didn't it ask why separating into small groups would make them more endangered/at risk??????????????????
