Select the correct statement regarding chemical synapses. Select the correct statement regarding chemical synapses. Neurotransmitter receptors are located on the axons terminals of cells. An action potential reaching the axon terminal causes a chemical signal to be transmitted across the synaptic cleft to the postsynaptic cell. Cells with gap junctions use chemical synapses. The release of neurotransmitter molecules gives cells the property of being electrically coupled.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

that is wrong, its not thymus.
