the picture of the kidney
(a) waste and water

(c) adh and aldos
it was (a) obviously, kidney excretes wastes and excess water, it would not excrete adh and aldosterone since they are used to change the permeability of the nephron membranes

I did [a] straight away... then went back through MC when I was done and changed it at the last minute.
Ugh. Model student gets the first thing wrong. :mad:

I thought that it was a fair paper. Yay, I got Q1 right - it was (A) then, after all none of the others fit the question anyway. Maybe ~75/100 for me on this one.

Omg that's crazy!! That's exactly what I wrote like word for word. The people who are talking about water baths are wrong because it said the storage temp affected the enzyme reaction not the temperature the reaction occurs at.
ummm water baths is also correct because storage temp and temp in which the reaction occured is the same thing u could have written the experiment either way water baths simulated different storage temperatures for the tomatoes

^ this. In fact, you'd probably lose a mark for not using water baths, as simply "placing it on the shelf" isn't maintaining a constant temperature (you have to repeat the experiment 10+ times, temperatures fluctuate throughout the day).

It was the cloning one, reminded me of the cloning process with Dolly. [me thinks it's the same one?]

Exactly! The things I focused more on studying hardly came up. :/
Plus I was dead this morning, so the things I revised quickly didn't stick. -.-
