Open circulatory systems,
They are always small organisms since diffusion is enough to transport oxygen and nutrients to their cells. Also you must say that the blood goes back to the heart by diffusion.

Closed circulatory system,
This is a more efficient method of transportation. This can be single (fish) or double (humans). You must mention gas exchange, volume to surface area ratio aswell.

The daphnia question is already ansered in the open cirulatory system.

Would anyone like to explain the roles of codons and anticodons in the translation process please :smile:

Haha may not be similar but its definitely harder. The thing I hate about Biology is that you can't get credited for extra knowledge which I think is ridiculous, surely if its relevant there should be at least some capacity for extra marks. It contrasts so much to my other two A2's - economics and politics - where in the essays i can throw in all the additional theories etc that i know.

totally agree. I sucked at bio in my first year cos I knew massively intricate things but I didn't answer the question how it was meant to be answered...

then suddenly got into medicine where it was all about knowing that intricate stuff, knowing more than you're meant to know and pushing the boundaries. trust me medicine is AMAZING. it's the best course you could ever do. let's not get started on that :P all i'll say is i hated bio but i love medicine - don't assume you've got to like bio to like medicine.

Can I just say your name (spunky monkey) is just awesome.
