WebThe central nervous system regulates reaction time. It comprises approximately 100 billion nerve cells (or neurons) that receive sensory input through sight , sound , smell, touch , and taste sensor signals. These signals are sent to the brain, where they are interpreted and converted into physical and mental responses. WebVideo transcript. - The rate of a chemical reaction is defined as the change in the concentration of a reactant or a product over the change in time, and concentration is in moles per liter, or molar, and time is in seconds. So we express the rate of a chemical reaction in molar per second. Molar per second sounds a lot like meters per second ...
