Question

if something is missing only 1 of the 8 characteristics of living things, then it is considered...
dead
non - living
living
semi - living

Explanation:

For something to be considered living, it must possess all the key characteristics of living things. If it is missing even one characteristic, it does not meet the criteria for being living. Non - living things lack one or more of these essential characteristics. Dead things were once living but no longer meet the criteria due to the cessation of life processes. Semi - living is not a recognized scientific term in this context.

Answer:

Non - living
