same! was so pissed off that nothing came up on the heart.

you should try the june 2009 paper. it has a good mix of both but mainly heart/cells stuff
I did this paper and there was one part on the heart, to label it but i spent about 3hours the day before on it and haemaglobin and nothing even came up. But, i was glad as i still did not know it that well. :rolleyes:

But surely nuclear division means mitosis (i.e. PMAT), so calc. would be 100-12=88?
in my revision it stated that nuclear divison was complete in metaphase.

For the effective gas exchange question, I wrote about the tissues because it specifically mentioned tissues in the question. I wrote about ciliated epithelium, goblet cells, elastic fibres, smooth muscle and cartilage. I done this as a mock the other day, so do you reckon I got the marks?
