Animal cells can use elements or ions to generate electrical impulses. These impulses are then conveyed from one cell to another, traveling across cellular networks.
The world's most commonly used system of measurement, the International System of Units (SI), was redefined in 2019. Since then, units have needed to be defined in terms of the constants of nature—that is, nature's rules ...
