The answer is heavy/dense
About 10% because I know about 90-95% of DNA is junk DNA(doesnt perform serious function)
I think the third one is the answer
If the Calvin cycle slows down, THE RATE OF OXYGEN PRODUCTION IN PS II WILL BE REDUCED.
This is because, the light reaction depends on the dark reaction to occur. If the Calvin cycle slows down, the light cycle will have less ADP and NADP+ to work with and this will slow down the production rate of the photosynthetic reaction.
Matter cannot be created or destroyed. this means that the number of atoms before the reaction has to equal the number of atoms after the reaction.
