I believe the statement would be that, A magnetic field created by the electric current causes the compass needle to move.
An electric current through a conductor creates a magnetic field,such that when a charged particle such as an electron, proton, or ion is in motion, magnetic lines of force rotate around the particle. Since current moving through the wire consists of electrons in motion, there is a magnetic field around the wire, which causes the compass needle to deflect.
This Is False I Believe. The Number Of Protons Is The Same As The Number Of Electrons , Not Valence Electrons

Answer:
Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.
Plants contain these things called chlorophyll, a green pigment that traps energy from sunlight. It absorbs red and blue light, which gives plants their green color. Hope this helps!
