Answer:
Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. Water and carbon dioxide combine to form carbonic acid (H2CO3), a weak acid that breaks (or “dissociates”) into hydrogen ions (H+) and bicarbonate ions (HCO3-).
Explanation:
Tracers are defined as elements
that can be monitored through biochemical reactions. This characteristic of tracers makes
them useful for the exploration of the mechanism of chemical reactions by
tracing the path that the they follow from reactants to products. A good
number of complex biochemical reactions (e.g. photosynthesis) have been studied
using tracers.
It is a complex of several proteins, pigments and other co factors that execute the primary energy conversion reactions for photosynthesis
