The central nervous system processes information received from the peripheral nervous system.
The central nervous system sends out the processed information to the peripheral nervous system.
The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
<span>Ions are another name for charged atoms. Some elements are electropositive, and some are electronegative. Electropositive elements such as metals like to give up electrons, thus taking on a positive charge. Electronegative elements such as chlorine attract electrons, so they become negative. When electropositive and electronegative atoms meet and exchange ions, they take on opposite charges. Because positive and negative charges attract, these charged atoms become attracted to one another. This attraction forms an ionic bond that keeps the ions together.</span>
<span> It should absorb the same amount of energy, assuming that the two reactions are exactly opposite.
