Question

The atomic number represents the number of which of the following subatomic particles in an atom's nucleus? A. Protons B. Electrons C. Neutrons D. Protons and electrons E. Protons, electrons and neutrons Muscle tone A. Is a condition in which stimuli occur so rapidly that there are no intervening relaxations. B. Is a constant tension produced by muscles for long periods of time C. Is a condition in which the muscle fiber only partially relaxes between contractions D. Is a time during which the tissue cannot respond again E. Results in complete and incomplete tetanus

Explanation / Answer

1) Atomic number of an element is the number of protons present in the nucleus of an atom. usually number of proton is equal to the number of electron. but in nucleus proton and neutron is present. so answer is proton.

2) muscle tone is a partial contraction of a muscle which is maintained even when muscles are at rest. so it is a constant tension produced by muscles for long periods of time.
