I'm hoping there going to be what they usually are so around 45 for an A*. I have a feeling it'll be higher though

Do you know how many marks 100 ums usually is? I hope the A* boundary is lower than usual at around 41 marks.

I don't really understand ums marks, sorry :colondollar:

I think it'll be higher more than anything, everyone I spoke to said how easy it was, but I really don't know

What did you write for the purpose of phosphorous? I wrote: for respiration and cell growth.

Phosphorus is especially important in root growth yes!
And used to make DNA :smile:

Yes, mentioned DNA too.
Any other questions?

Strange.. Well I though it was okay, I think it just paralleled to all the past papers so

I was happy when I saw that question. Difference = fish have a two-chambered heart and humans have four.
The question before that one asked you to explain what is meant by single circulatory system. I wrote that the blood passes through the heart once in a full circuit.

Yeah I wrote Joanna

Original post by QuantumSuicide

Yeah I wrote that for the first question, but I combined some other stuff with the second (can't remember what) as I thought they wouldn't ask you something that was written in the question...

Who was correct about 30 degrees being the best temperature? Explain why?

Writing about root growth is right, HOWEVER,
Phosphates are for DNA and making cell membranes. I think they require you to name the basic things it does for the plant, just like nitrates is for making amino acids and proteins.

ALL of the minerals are for plant growth so just saying growth will probably be too vague. :s-smilie:
