what is bacteria and virus? definition
Answers
The biological difference between bacteria and viruses:
* Bacteria are single-celled organisms that live all around us — including inside our gut. Most bacteria aren't harmful, and some are even protective. However, a small percentage can be harmful and cause illness.
* Viruses are parasitic, which means they need a live host in order to survive. Viruses infect the cells of living beings, including humans, and can cause diseases like the common cold or AIDS. Although most viruses are potentially harmful, some can actually be beneficial
Answer:
Bacteria
A member of large group of unicellular microorganisms which have cells walls but lack of organelles and an organized nucleus, including some which can cause diseases.
Virus
An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
