For the leaves to be presearved as fossil, they have to undergo a natural process of carbonization. This involves a slow chemical reaction with water over time that allows oxygen, nitrogen, and hydrogen to escape the leaves’ structure as gases leaving behind a carbon skeleton/film.
SO2: inorganic compound
k: element
Cl2: inorganic elemental molecule
C6H6: organic compound
Because for each glucose molecule there are two pyruvic acid molecules entering the system, two ATP molecules are formed. Also during the Krebs cycle<span>, the two carbon atoms of acetyl-CoA are released, and each forms a carbon dioxide molecule.</span>
Answer:
Homologous structures have the same ancestry, but may no longer serve the same function. For example, the bones that make up human fingers were inherited from an ancestor that's shared by all mammals.
