It needs to be examined microscopically because you can't see the bacteria or virus with your bare eye. The average bacteria is only 0.2 to 2.0 micrometers in size.
They need water and sunlight.
Green plants, most algae and some bacteria need access to sunlight, or a source of broad -spectrum visible and UV light. This is because these organisms derive energy from the light.
no, some bacteria are heterotrophic and some are autotrophic. Most bacteria are heterotrophic though.
Some bacteria do, but most don't. Vitamins are used by multicellular organisms for signalling and to modulate nutrient uptake and the immune system; the bacteria simply keeps its own cytoplasm clean without the need for vitamins.
Humans need soil bacteria for various reasons, including nutrient cycling, decomposition of organic matter, and promoting plant growth. Soil bacteria also help in breaking down pollutants and supporting a healthy ecosystem. Additionally, some soil bacteria can have beneficial effects on human health, such as producing antibiotics and aiding in digestion.
The bacteria in frozen food die. This is because bacteria need food, water, and a warm temperature in order to survive.
These bacteria help in digestion and in destroying harmful organisms. Intestinal bacteria also produce some vitamins needed by the body.
It depends on the bacteria. Some need a lot of oxygen, some only a little and in some oxygen will kill them. While most bacteria live in a narrow range of pH, some will be able to live in higher or lower ranges.

Bacteria are extremely simple organisms. Most bacteria are a single cell, and are supported perfectly by sunlight alone. Some kinds of bacteria can live deep underwater, or encased in thousands of tons of rock. Some can even live in space. Overall bacteria do not need oxygen/nitrogen for any reason, because there body's do not need it to function, they are just to small and simple.
As with other building materials, knowledge of the history of the construction can help you eliminate some materials that are too new to contain asbestos. For the rest, the only way to determine with certainty if asbestos is present is to have a sample sent to a lab and examined microscopically. Many materials can be examined in a polarized light microscope to determine whether and how much asbestos is present. However, because of the way flooring materials are made, it is usually necessary to examine the same with an electron microscopy to be certain that asbestos is not present.
Bacteria require water for several key physiological processes, including nutrient uptake, metabolism, and cellular respiration. Water is essential for the movement of molecules within the cell and the maintenance of cell structure. Without water, bacteria would not be able to grow and reproduce effectively.
Because some of the bacteria in the human body fights off diseases, and some cause them. for example, in your antibodies, you have a bacteria that fights certain sickness. Also, a type of bacteria helps you digest food. That's why it's not safe to drink hand sanitizer.
some sense
some genes are skinny some are boot cut but bacteria are bacteria
It all depends on the bacteria. Some require oxygen, some no oxygen and some only a little. They need certain food types (substrates) and certain chemicals.It all depends on the bacteria.
