Answer: A
Explanation: Protons and neutrons form the nucleus of the atom, with electrons orbiting it.
Number 4 is
-Oxidation occurs at the anode, while reduction occurs at the cathode. Recharging a battery involves the conversion of electrical energy to chemical energy. During recharging, there is movement of electrons from an external power source to the anode, and on the other side electrons are removed from the cathode.
That would be C. Organelles
