Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
Explanation:
Atomic number=protons=neutrons or, A-P-E. So, an element like this doesn't exist because protons and electrons have the same number.
Answer:
Yes
Explanation:
Two isotopes of hydrogen, tritium and protium, undergo nuclear fusion in the sun to give helium, neutrons and a tremendous amount of energy. This reaction occurs at the very high temperature found in the sun and yields tremendous amount of energy.
Given the high temperature at which the said fusion reaction occurs, it is safe to say that hydrogen and helium act as a furnace at the core of the sun.
