Question

Is growth ofbody (human) a physical change or a chemical change?

Answer 1

Growth of a human body is both a physical change as well as a chemical change. Growth involves change in the overall size of human body and a change in any one of the physical properties (like shape, size, colour, and state) is called a physical change.

It is also a chemical change because it is a biochemical process regulated by hormones and enzymes.
