Answer» Answer: 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. |
