Explanation:
Plasma membrane:- a microscopic membrane of lipids and proteins which forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and regulates the passage of molecules in and out of the cytoplasm.
Atomic mass:- the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Energy:- the strength and vitality required for sustained physical or mental activity.
a microscopic member of Lipid and protein is called Plasma membrane
A Mass of a atom substance is called atomic mass
