To describe the structure of HNO3, two resonance structures are needed.
Many different structures are needed by the digestive system to function different parts of the digestive system.
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.

We have different structures that perform different functions so the body can be more efficient.

Chloroplast, which contains the chlorophyll needed to use the photons of light to produce the glucose molecules for the plants
The digestive system is made up of many structures. Humans need different structures to process the varieties of foods we eat on a daily basis.
