    You make it sound even more complicated :/ If copper carbonate is insoluble, it shoud not be written in the ionic form. That's what I know from books :P And this question is doing the complete opposite.

    Can you tell the whole question? Maybe it's because more heat is lost to the surroundings as temperature of water increases?

    Yeah I got what ur saying, but I dont think that's what they are talking about. If they were, they would have just written about the carbon cycle. And ths point was written with fossil fuels and Energy changes.. :/

    You just have to randomly draw them. For eg, the first gene circle shaded, second gene also shaded, but third not shaded. As it actually wants us to show meiosis, which is random, u can just choose whichever you want but the figure should be the same :P
