what is bacteria and viruses
Answers
Bacteria are single-celled, living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources. Viruses are not considered to be “living” because they require a host cell to survive long-term, for energy, and to reproduce.
Bacteria are prokaryotic microorganisms. They are found everywhere. They can survive even the harshest of conditions such as hot springs, deep ocean, snow and even in the volcanos. Disease-causing bacteria are known as pathogens.
Virus are extremely small entities which contain either RNA or DNA as the genetic material. They are also smaller than most bacteria.
Virus are not fully acknowledged as living organisms as they cannot survive outside a host. Anatomically, a typical virus is girdled by a protein coat that is enclosed by a membrane made of proteins. In some virus, this protein coat is covered by a lipid membrane called the viral envelope
