The simplest structural units into which a complex multicellular organism can be divided and still retain the functional characteristic of life, are called cells. One of the unifying generalisations of biology is that certain fundamental activities are common to almost all cells and repre..

The units of fundamental physical quantities are called fundamental units. They are length, mass and time. These units can neither be derived from one another nor can be resolved into any other units. They are independent of one anothe..
