What's the electric charge of a neuron?
This question is set incorrectly I think.
The question should refer to a neutron and not a neuron for
electrical charge.
Neutrons are chargeless particles that associate with charged
protons in the nuclei of atoms.
Neurons are nerve cells in the nervous systems and are typically
also charged, ie, have membrane potentials, thus allowing
transmission of nervous signals in the body.
So if you scored 7/8 and got this question wrong, I will moderate
and void this question and say you got full marks and WELL
DONE.
