Viruses are biological particles which are causative agents of various diseases and examples of which are the herpes simplex virus, adenovirus, and vaccinia virus. Infections are caused by viruses only under specific conditions wherein they are situated inside a living host cell, an event which accounts for its intracellular nature of existence and infection.

The incidence of obesity has become a major health issue that is barely unrecognized in every medical journal. Despite widely researched works on the pathogenesis of obesity, it is rather unfortunate that it remains a life-threatening health risk in susceptible individuals. The onset of obesity is gradual in form and arises from daily accumulation of fat in adipose tissues in excess of body anabolic needs (building up process). One can trace fat storage in humans to the adaptive need for energy...

The contemporary theory of evolution, according to Nardo (2009), was developed by a proletarian English naturalist known as Charles Darwin, in the 19th century.

This theory proposed that random mutations on the gene occur...
