Oxygen is also called a life supporting gas?why​

Explanation:

Oxygen is also called a life supporting gas because oxygen is required in the process of cellular respiration.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
