Summary Introduction
Introduction: Those organisms which form the connecting link between the living and non-living organisms are called “virus”. The size of the virus is very small and varies from 20 to 300 nm. Nutrition obtained by the virus from the body of the host is later contributed to the production of its clone copies. The absence of the host body in the life cycle of the virus makes the virus inactive.

Students have asked these similar questions
Which of the following statements concerning viruses and human health is false?
a-in many diseases caused by viruses, the virus attacks cells as it reproduces
b- many viral diseases can be controlled through vaccinations
c- some viruses can remain dormant in the body for years before disease symptoms appear
d-most viral infections are difficult to treat, but they can be finally destroyed by antibiotics
According to the seven characteristics of life (1- composed of one or more cells, 2- compelx and organized, 3- respond to environment, 4- grow, develop, and reproduce, 5- obtain and use energy, 6- mainatin homeostasis, 7- allow for evolutionary adaptation), are viruses alive?
According to your own understanding, what do you think makes viruses some of the most common disease causing organisms? Explain comprehensively
