There are nine different characteristics of living organisms. I will explain each characteristic and give reasoning why a virus, prion, viroid and are not considered to be alive. I will also answer how things like these that are not considered to be alive “evolve”. Order is how organisms maintain structure with each other, I like to example this by looking at the laws that govern our nation. They are what creates order for human beings. Metabolism is the method of breaking down food to create energy. Motility is an organism creating movement through the process of exerting energy. Responsiveness is when an organism gives reaction to its environment, like when put your foot into a cold pool, normally the reaction is to pull it out. Reproduction is an organism creating another form of itself. Development is progress or growth

Viruses are acellular particles, meaning they aren't made up of living cells like plants and animals are. Prions do not contain any DNA or RNA. Viroids are small single cell plant organisms that produce a single specific RNA molecule.

If we take the meaning of “evolve” to mean change over time, then yes, they do indeed evolve....

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
