The controlled timing of gene expression is crucial to an organism because it allows for which of the following? differentiation specialization development all of the above

I would say differontiatio but not completely sure

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.

Your answer is water because there is combined mass of water found on, under, and over the surface of a planet. your answer is water.
