For the candle question, it went out bc there was no oxygen and when they put the plant there it released oxygen through photosynthesis? Idk if that's right

Yeah I put that and that the candle doesn't release any more carbon dioxide for the plant to photosynthesise further, hence only stayed alight for another 2 minutes

I’ve messed up the heart question! I got everything right except the names of the valves. I said the semi lunar valve when it was meant to be the triscupid if you get me. On both sides.. how many marks will I drop?

Yeah I still put the bit about oxygen and photosynthesis so
(Original post by Cam3r0n)
The combustion of the candle does produce carbon dioxide, I think? If it does then it would stop because the combined intake of oxygen for respiration and combustion is at a higher rate than the production of oxygen in photosynthesis.
