unfortunately, this question is incomplete, it relates to processes that occur
in cells. Catabolic processes involve the breaking down of molecules to release
energy. In anabolic processes, this energy is used facilitate a succession of
chemical reactions to build up larger molecules from smaller component molecules.</span>
Hydrogen and oxygen are often found in the form of H2O but even if hydrogen surpasses oxygène in number it doesn't when it comes to mass because M(O) = approximately x16 M(H)
The earthworm has a closed circulatory system, and there are 3 main vessels: <span>aortic arches, dorsal blood vessels, and ventral blood vessels.
