Answer: chemical reactions
Explanation: The function of an enzyme is to speed up chemical reactions. They do this by lowering the activation energy, which is the minimum energy that must be available for a chemical reaction to occur. If the energy required is lowered, the reaction can go faster.
Index fossils (also known as guide
fossils, indicator fossils or zone
fossils) are fossils used to define
and identify geologic periods (or
faunal stages).
It might not be a good idea as nitrogen may be needed by plants in several cellular processes and eliminating nitrogen uptake might severely impair these functions if there are no alternatives to these pathways
It indicates where the energy is going.
