Exoskeleton
Exoskeleton is a evolutionary innovation. This is operated by muscles attached to it and acts as an armor. Other than support this is an adaptive mechanism to provide protection against predators. In vertebrates, it is considered as the dermal bone that developed via membranous ossification. Fishes retained their exoskeleton in the form of their scales. However, in some organisms terrestrial evolution allows the loss of exoskeleton and formed a more mobile endoskeleton,

Answer:
B. Dehydration synthesis
Explanation:
Adenosine diphosphate (ADP) and Adenosine triphosphate (ATP) are currencies of energy found in plant and animal cells. They are also nucleotides found in the mitochondria in the cytoplasm of the cell.
Cellular oxidation in a cycle of enzyme-catalyzed metabolic reactions, known as Carboxylic/Krebs cycle. ATP synthase is a huge molecular complex and has a function of catalysing the addition of a third phosphorous group to form ATP through rehydration synthesis. The reverse of this reaction; production of ADP from ATP is called hydrolysis.
