In my opinion I don’t necessarily believe viruses are alive because of the fact that viruses can't reproduce on there own, they need a cell to reproduce. If you had a looser definition of alive then maybe they can be considered alive. I also beileve there not alive because according to the seven characteristics of life for something to be...
