Which two points are known as the twin characteristics of growth?

• A. I and II
• B. II and IV
• C. II and III
• D. I and III

Answer 1

The correct option is B II and IV

There is an increase of mass in the living as well as non-living things, therefore the criteria of mass are not included in this.

Differentiation is referred to as the division of labor into a cell or tissue. This is also a criterion for living beings.

Increasing the number of individuals is not a criterion for living being because it is referred to as an entire population and not a single being.

Response to the external stimuli is and criteria which only living beings show and not the non-living beings.

So, the correct option is 'II and IV'
