Maynnn xD I wrote the same Ca ion thing in both so I'm definitely losing 4 marks xD
And what about the habituating planning?
And was bundle of His 4 and AVN 3rd?

For habituation, I wrote acclimatisation, put 5 scarecrow in the field, measure original number of crop, time period of 30days and measure crop number uneaten at interval of 5 days, repetition

As I knew, 1 is SAN , 2 is delaying of impulse , 3 is AVN and 4 is bundle of his

x ray is just CT, action is fMRI and the last one was fMRI and MRI

I made an explanation the best I could, but it kind of worried me that it wasn't really related to anything we had learned.. we never had much questions like that is past papers I think?
