Which of the four molecules has the highest amount of stored energy? Carbon dioxide water oxygen glucose

Glucose

Explanation:

Glucose has the highest amount of stored energy that the others because glucose posses more chemical bonds which can undergo rearrangement as a result of chemical reactions. When the bonds are rearranged there is release of energy meaning that the bonds in glucose consist of stored energy. Water, carbondioxide and oxygen does not have much chemical bonds compared to glucose, hence they don't have stored chemical energy.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
