For the black bottle, the lower the light intensity, the lower the rate of photosynthesis. This condition can be comparable to plants at night, as pondweed respire under that condition which is the reason why oxygen levels drop as oxygen are taken in by the pondweed in order to break down glucose.

The exam wasn't too hard either. I really screwed up in the Chemistry 6 marker, I balanced the equation but mixed up bonding, I put covalent bonding where the answer was supposed to be ionic and for the first two questions in the C4 section, yep mixed them up too 
The rest was easy though, especially the Physics 6 marker, I revised Radioactive Decay thoroughly so I was especially happy about that.

I did 29 for neutron, and 26 for electron and proton because protons and electrons have the same atomic number or somethong like that...idk if thats right though?

I found this paper difficult! Was the answer to the physics resistance question 4.5 or 2.5 ohms?
