Carbon contributes an electron, and Hydrogen contributes an electron. The sharing of a single electron pair is termed a single bond. When two pairs of electrons are shared, a double bond results, as in carbon dioxide.
Elements of nervous system involved in motor coordinationEdit. The red nucleus is mainly involved in motor coordination of the muscles of the shoulder and upper arm, but it has some control over the lower arm and hand as well.
Motor Skills are Essential to Learning! What are motor skills? A motor skill is a function, which involves the precise movement of muscles with the intent to perform a specific act. Most purposeful movement requires the ability to feel or sense what one's muscles are doing as they perform the act. Motor difficulties occur when an individual lacks the ability to move in the way he or she originally intended. This can have a significant effect on classroom performance and motivation in school.
