Water is the single source as it provides the electrons by splitting into oxygen and hydrogen. This process happens during the light-dependent reactions.
I do not know but does it depend on how big or what the temperature is
the skin has cells like that
The statement above is TRUE.
RNA hydrolysis is a reaction in which a phosphodiester bond in the sugar phosphate backbone of RNA is broken, thus cleaving the RNA molecule.
This reaction is made possible in RNA because the ribose sugar in RNA has hydroxyl group at the two prime position.
