Ah sehr interessant...I'm clueless as to how I should revise

I wrote In situ, I thought ex situ was what they'd already done?

Sounds good I said do more readings between the values 0.2 and 0.3 to determine the concentration of sucrose where the change in mass is zero rather than plot a calibration curve. Do u think this would be accepted?

youre probably right. I don't know biology.

Did anyone else get 0.63 for the chromatography MCQ

Ohh damn I didnt know you had to convert it into cm Thanks anyway

Was the question on ventricular sistole 0.2-0.3 right?

Where'd you hear that?

6600% increase in oxygen
1005 cm^3
28% guanine

Were there any other maths questions?

Was the question on ventricular sistole 0.2-0.3 right?

can someone predict the grade boundaries?
just want an idea

How are two polynucleotides in DNA held together:

- Adenine pairs to Thymine, Cytosine pairs to Guanine
- 2 Hydrogen bonds between A and T, 3 Hydrogen bonds between G and C
- A purine bonds to a pyramidine

THis is what i put for that question

Would around 53-55 be an A? I don't know how much the grade boundaries are going to shift but i feel like a lot of people found it easy..

Did anyone put the hinge region for the antibody MCQ?

Surely you'd have to mention complementary base pairing.
