Question

why is molecular movement is the most important criteria of deciding whether something is alive?​

Answer 1

Explanation:

Living organisms must keep repairing and maintaining their body structures. All these structures are made up of molecules. They must be capable of moving molecules around, all the time. So, molecular movement is one necessary criterion for something to be alive.

Answer 2

All living things move by themselves without any external help . In some cases the movements of living things are quite fast which can be easily observed but in other cases the movements are very slow and hence observed with difficulty .

Thus , molecular movement is the most

important criteria to decide whether

something is alive .
