They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.

What are 2 types of bacteria that make us ill?
Infectious bacteria (those that do make you sick) slip into your body and live among your healthy cells. Many emit chemicals called toxins, which can damage tissue. Streptococcus (strep), Staphylococcus (staph) and E. coli are some of the more commonly known bacteria that can cause infections.
Where is the most bacteria found in the human body?
Your gut is home to most of the microbes in your body, but your skin, mouth, lungs, and genitalia also harbour diverse populations. And as research continues into body biomes, it should reveal answers about how these microorganisms are promoting health or even disease.
What are the 2 types of bacteria?

What are the main features of bacteria?
There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size. Not all prokaryotes are bacteria, some are archaea, which although they share common physicals features to bacteria, are ancestrally different from bacteria.

Why are viruses considered non living?
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Are viruses alive Yes or no?
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Does coronavirus stay on clothes?
This is why it’s important to wash your hands frequently, avoid touching your face and clean and disinfect commonly touched surfaces every day. Unfortunately, the same study didn’t examine how long the virus can survive on fabrics — so it remains a possibility that coronavirus can live on clothes for several hours.
