Explanation
D: Iso is the prefix that is often used with scientific terms to indicate that something is the same, equal or constant.
For example, "isometric" means having equal measurements or dimensions, "isothermal" means having constant temperature, "isotonic" means having equal tension or pressure, and "isomer" means having the same molecular formula but a different arrangement of atoms. The prefix "iso" is derived from the Greek word "isos" meaning "equal" or "same." It is commonly used in the fields of chemistry, physics, and engineering to describe properties or processes that are uniform or constant.
