I really liked the paper! The essay was brilliant :smile:

I didn't like the sand dune question it wasn't too sure of what to write so i just kinda waffled on about measuring out a grid at each position to be sampled and then using a random number calculator to get a random cooridinate to place the quadrat... i didnt wanna write about a belt transect cause i didnt think it could be done randomly :s-smilie:

What did people write about the enzyme that fungi secrete to help them break down the dead material?? My mind went blank

Really good paper. Happy with how it went as I admit I didnt do much revision at all! The fungi enzyme baffled me too I think I made something totally random up lol. What did people put for the irregular heart beat question and the labels for the photo?

For the irregular heartbeat i wrote because the spikes that indicated ventricular systole where at irregular intervals? I didnt know if that was right or not as ive never really seen a quedtion aboutthat... the top photograph was the phloem and the structure Z was the sieve plate... The bottom picture was the xylem and for the calculation i got that the actual size of Z was 30um.
