I hope these are right, hope this helped.
I believe it is a 2:1 ratio of hydrogen to oxygen, because the way i learned was that carbon hydrogen and oxygen have a ratio of 1:2:1, respectively.
Relating to development involves the specialization of CELLS by form and function, and NOT the entire organism?
differentiation, morphogenesis or growth?
I think the answer is differentiation.
