Just wondering how everyone found the biology paper today? I thought some questions were quite challenging, but generally, it wasn't too bad!

I had to check the front page to see it was higher, it was so damn easy I couldn't believe it. They will probably increase the grade boundaries because everyone I know said it was easy.

I said that the oviduct was inside the woman's body and so would require invasive surgery but the testes were outside and wouldn't... What did everyone get for the one about lily pads and guard cells?? And about the upland and lowland rice??

Guard cells are on top on a water lily as underwater gases would not be able to diffuse etc. And lowland rice get extra nutrients of to leeching through the soil I think...

I put for upland and lowland that nutrients in the sooil may be dofferent. Was the question on the plant functions, structure D stomata or guard cells?

Yes October had 4 readings higher than any other month, April was the month where people could not swim because the pollution level was considerably high as the disk disappeared early which means that the water was not clear and therefore polluted !!
