21st century science OCR B456

What did you guys answer for the tick box question on the second page?
I guessed the middle three boxes on the last second of the exam

I put the one about only respiring at night, and also the one about water vapour but I can't remember which other box I ticked...I definitely think I mucked up that exam. Oh well, there goes my a* in biology

How did you think the b456 exam went today guys?

Not bad, what did you put for the ratio question?

96:5

I thought it was fairly straightforward, although seeing everyone else's response, I may have messed up the last question. I didn't write that it was a reflex arc, instead I put it as a stimulated response because in my revision guide it gave an example just like the question and said it wasn't a reflex response...oh well

I put the one about only respiring at night, and also the one about water vapour but I can't remember which other box I ticked...I definitely think I mucked up that exam. Oh well, there goes my a* in biology

HOw did you all do on the ratio question?

what did you get?

What did you put down for the ethical issues and i think i did the same exact mistake as you for the final question, i first talked about the reflex response which i guess is correct but then i crossed it out and then talked about the CNS and etc.

I wrote 19.2
however some people did say it had to be in ratio form of 1:19.2
But i think that equation did equate to you calculating the ratio overall. Markscheme may allow valid other answers

I got 19.2:1 as well?

hopefully should be right i just left it as a number 19.2 >.< other people did write 1:19.2 so you probably have got it correct
