It has been estimated that over gald the nbeurons of the brain are in astructure that cinbsitutes oinly 10 percent of the brains
LUCKY_DIMON [66]

Answer:

Over half the neurons of the brain are in a structure that constitutes only 10 percent of the brain’s total mass this structure is the cerebellum.

Explanation:

More than 50% of the brain's overall neurons are found in the cerebellum, although making up just about 10% of the brain's entire volume. The cerebellum has traditionally been thought to be a motor structure since cerebellar injury affects the position and motor function, as well as the bulk of the cerebellum's outputs, go to the motor neurons. The cerebellum does not originate motor orders; instead, it changes descending paths' control signals to improve the adaptability and precision of movements. Moreover, the cerebellum is responsible for many functions in the body including movements, vision, and balance, etc.

Firstly, you can vary the number of different amino acid that you use to make a protein.
Secondly, you can also vary the length of the amino acid chain.
And thirdly, when an amino acid chain is formed different parts of the chain interact with each other, bonding chemically, forming different 3-dimensional structures of the protein.
All of this contributes to the vast variation in proteins.</span>
