The correct answer is protons and electrons.
Atoms are made of particles called protons (p+), neutrons (n0), and electrons (e-).
Protons and neutrons are located in the center of the atom, making up the nucleus and electrons surround the nucleus.
The charge on the proton and electron are exactly the same size but opposite and their number in the atom is the same when we talk about neutral atoms. Ions are charged atoms, so the number of their electrons and protons are different (for example, positive ions have more protons).
Answer:
The human body have two parts of nervous sytem the peripheral nervous system and the central nervous system
Explanation:
Peripheral nervous system contain all the nerves and ganglion that lies out side of the spinal cord and the brain.These two systems communicate with each other to make the body functional. The main function of the PNS is to connect the CNS to limbs and organs. Unlike the CNS the PNS is not protected by the vertebral column and skull.The peripheral nervous system is divided in to the somatic nervous system and the autonomic nervous system. The autonomic nervous control on the smooth muscles and glands.The connection between the CNS and organs keeps the body in sympathetic or parasympathetic condition.
