Yes! I hate ecology (lol you should've read my comments on it on the night before the exam). I did the Question 3 as well for the Unit 6 exam. I was going to do the other one (4B) but I realised I had some doubt as to whether the xylem carries mineral ions or the phloem. For the Unit 5B question (regarding the cell wall) I put in amylopectin. I don't know why, I just did. At one point I was going to write the middle lamella. LOL
ooh and nope i dont do maths...i do philosophyðics instead!
hey! ach chem food science was hard especially the Q on pectin..guessed so many of the Qs! i said cellulose and rhamnose..lol rhamnose was a complete and utter guess the name just sounded familiar so i wrote it down...but dont hold much hope for that question...and yeah biology i did unit 4 in january...and unit 5 was awwwwful all on ecology not real biology! just came home from unit 6...i thought it was quite good did the essay Q on DNA..how did you find it? nuffield chemo unit 6 tomorrow eh...gonna be a tough one :/ good luck!x
EDIT: Wait! You do Edexcel Biology too? Do you do Human or normal Biology. And how was Unit 5/4 for you? I do the food science option? BTW, do you do Maths as well? I'm on Edexcel syllabus.
You do Nuffield Chem eh? Arguably the hardest chemistry syllabus. That unit 5 food science paper was totally out there. I can't believe they asked so much stuff about Pectin! FRICK! What did you write for the two components of a cell wall other than pectin?
