AQA AS Biology 7401/1 and 7401/2 Exam - 26th May and 7th June 2016

It was 66.7

But how is it possible to have .7 of a heartbeat?

Was this the tick box one with a table?

0.9 seconds represents 1 heart beat

heart-rate x min^-1 is the same as heat-rate x 1/60

So 1 heart beat was 0.9x1/60= 0.9/60 =66.7 heart rate

I honestly can't remember.

I remember that the ventricle pumped blood out once per second, which is why I said 60 because I don't see how the .7 is possible. They were both 1 markers anyway right?

It depends on what you got as one beat, I think you got the beat as 1sec^-1 so you put 60, but it was 0.9 not 1
And yh 1 mark. Stroke vol was 120-50=70

No marks for writing degenerate, because that won't cause a non functioning protien or what ever it said. I don't think you had to talk about frame shift. Talk about DNA base sequence amino acid sequence tertiary sequence and non longer complementary for full marks

Would i lose all the marks for saying it changes the variable region, i meant to say it changes the variable group, but they could mean the say thing right? Region/group similar.

Cool, grade boundary predictions?

You won't lose any marks they will have like 5 things you could say for 3 marks. Did you say no longer complementary?

Unlikely I'd say. Not 80 but shouldn't be that low. Maybe 74-75% for an A

Really that low??

Doubt it, we didn't do an ISA, we had to do all the units in one exam, and it's a new spec in 2009 new spec an A was 67%

I go to a grammar school and our head of biology said both papers were hard so hopefully the grade boundaries will be low! 🙏🙏🙏

I don't go to a grammar school and my teacher said they were very fair papers
