I hope.Yeah, hepatic portal vein and ileumdry mass, i put measure the amount of solution uptaken by the plants., and then subtract from original. I think its wrong.yea thats wrond dude.... uve gotta bake the radish plant to find the dry mass..!

over all ws it easy, hard? how do u think the threshold will be? i thoght it was very long, one thing. it was very "geo" like, u noe sooo many lines for each questions wid like 5 marks and all, weird, haha.bt it was ok for me i gess
I totally messed up with the Natural selection question[5mks]But the paper was little bit hard compared to 2008.Threshold will be 50/80 for A

They measure the dry mass every week. Im getting more and more confident that my answer has a SMALL chance of being correct.

Thats what the experiment says nid. They measure the growth of the plant for 6 weeks. They wont use different plants.
The natural selection answer was because the sickle cell hetero ppl cant get malaria right? So the survive due to survival of fittest, and they pass the trait onto their children right?

They wont use different plants.it says in the Hodder Murray revision guide, By the way, so it s gotta be rite. theres no 2 ways about it, to find the dry mass uve gotta bake the organism, even if cells denature etc etc

So if U subtract the mass of water absorb from the mass of radish u get the dry mass.
