In general viruses are disease-causing agents composed only of nucleic acid enclosed by a protein coat. In attempting to treat viral diseases, a recurring problem is that as new viruses are made by infected host cells their characteristics may differ from those of the virus that directs their production. Which characteristic of living organisms does this represent?
a)irritability.
b)cellular structure.
c)homeostasis.
d)reproduction.
e)evolution.

I would say evolution. Most viruses don't undergo the same rigorous quality control during replication that our own genomes due, so mutations are introduced in the virus genome with each replication. If a particular genome produces a virus that's a more effective replicator (for example, if the changed genome makes the virus more capable of evading the host immune system) then that genotype will increase in frequency. Over time, you can track changes in the different types of virus within a single subject.

There are definitely newer types as much as we want to stay away or run away from them.The new age diseases which are mostly viral are very contagious and deadly.Medical Billing Software
