An investigation that shows what elements are present in the body composition of this substance.
Explanation:
All living organisms, without exception, have carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur in their composition.

If there is a presence of these substances, we can test whether this substance responds to external stimuli, if it responds it is because it is a living being.
