ALL OTHERS CORREC TFC

[Footy Chick]

Ok what about these..

3. Uracil?

11. Is either diffusion or osmosis

12. Chloroplasts (logical really)

17. I read the question wrong (just as I did in exams..how appropriate and I was thinking of mitosis anyway. I'll take another stab.. this always annoyed me, which 2nd stage? there is a 2nd stage of 4 phases? Bugger it, I'll just say 46
