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.

Answer:
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.
Explanation:
Genetic variations are important because a diverse gene pool is good for long-term survival of a species since the environment is always changing, so the diversity of DNA offers the most fit of the species a better chance of surviving because they are most adapted to the constantly changing environment.
