Antiviral drugs are most often designed and developed to combat specific viruses and sub-categories of viruses: HIV, Flu, Herpes, Shingles, Cold sores, Canker sores, etc.
Because viruses are not bacteria. Antibiotics only work on bacteria. (Viruses are not actually alive . . . they enter a bacterium and take control of its function.)
Viruses do not have complex membranes like eukaryotic organisms have. Viruses also do not have cells, nor are they technically living organisms. There is no need for viruses to control the movement of material in and out of the viral particles.
Viruses are considered to be a serious threat to humans because they are very difficult to control. Very few things can control viruses except antivirals.
Population control
- some viruses can be used in biological weapons- some viruses are used in the fight against pests
Electron Microscopes are used to study viruses.
Since viruses are non-living they do not need to get rid of waste as they do not make any. Their host does, however. The host can't control the amount of waste build up as the virus has control of the DNA and it only wants to make more viruses.

Viruses do not directly need energy. The virus takes control of the host cell in order to replicate. The host cell's own metabolic machinery is used to synthesize the components of new viruses. The virus itself is passive.
u make sure you up
sponges has medicinal potential due to the precence of sponges themselves or their microbial symbionts of chemicals that may be used to control viruses bacterial and fungi.
Viruses can be labeled as RNA or DNA viruses and they can be said to have an envelope or to be "naked".
