But if you consider how many times Earth would fit in the Sun, then you realise that our reasoning was totally stupid! lol
For example, I imagine there is a higher rate of parents getting the chicken pox answer correct than adult non-parents - especially parents who were around before the vaccine. That doesn't make adults smarter than non-parents. It's just trivia.
I honestly dont think I remember anything I learned in history class. (Only the stuff I allready knew beforehand) I cant think of anything I learned there now anyway, trying hard to think of something.
(I do like history though, but more about civilisations and not about dates of wars and names of generals etc)
Mitochondria is the powerhouse of the cell!
The word "heavy" generally refers to weight and not mass so question one should probably ask which has the higher mass, not which is heavier.
A better answer to question 8 would probably be to conduct aerobic respiration, as energy is not really "generated" per se, it is released from the glucose and oxygen.
An amount of energy is always measured in joules (or some equivalent unit such as electron-volts or kilowatt-hours), so for question 12 the question could be phrased more generally (though it is fine as it is).
Overall a very good quiz though.
