How many harmful bacteria live on Earth?
AnswerThere are a lot of bacteria all over the world that affect the environment and the creatures that live within them, including humans. Estimating their number, though, is both difficult and largely meaningless. For example, even a simple infection on one person (such as an infected cut), may contain billions of separate bacteria. trying to estimate quantities worldwide would involve numbers that are simply too large to be useful.
There are many bacteria that serve beneficial roles. Bacteria in the environment break down dead matter and waste, allowing it to be re-used by other living things. Some soil bacteria convert nitrogen into a form that plants can use, allowing them to grow. Many animals, including humans, have bacteria in their digestive tracts that aid in digestion and protect against harmful bacteria. We could not live without bacteria.
Normally this would come under biology, However many bacteria are involved in geological processes (e.g. stromatolites) and it has been found that bacteria live deep down in the rocks of the planet. Thus were bacteria are involved in this way their study would be of concern to the earth scientists too.
Counting all the bacteria on earth is is impossible. Even estimating is nearly impossible. my guess is: 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 and probably more then that!!
Yes. There are billions of different bacteria living inside your mouth. About 100,000 per tooth and millions on your tongue. The only way to get rid of harmful bacteria is wash your mouth daily and brush your teeth 3 times a day. Many of the bacteria is harmful that lives in your mouth so be careful what you put inside it because then it could multiply!
Two roles of helpful bacteria are ♥ to keep the numbers of harmful bacteria in check. They do this by occupying the skin space, leaving little or no room for harmful bacteria to reproduce and grow and ♥ to produce acids that lower the skin pH. Many disease causing microflora do not survive well in a low pH environment.
Bacteria can be categorized as living cells unlike viruses. Bacteria are found everywhere from the tallest mountains to the deepest parts of an ocean on earth. The air is replete with bacteria. Certain bacteria spend their whole lives in the atmosphere, reproducing and growing in the clouds. Although bacteria lack distinct nuclear structures common to the cells of higher organisms like animals and plants and are able to reproduce successfully and transfer genetic information from…
It depends on what kind of bacteria you're talking about. Many bacteria in our own bodies are useful and helpful - for example, the bacteria in our digestive system that takes food and converts it in to the elements we need to survive. Other bacteria can be deadly, such a staph bacteria that cause infections. Bottom line is that not all bactiera are harmful.
Both bacteria and the lining cells of the intestinal tract have to have mutual attractive proteins. These will allow the bacteria affect the other cells. Many do not and they have no bad effect. We do have billions of bacteria that are beneficial and not harmful. The digestive tract is their normal habitat.
Bacteria are small, single-cell organisms that are both beneficial and harmful to human beings. Some forms of bacteria help us to live, such as those that help to break down food in our intestines. Other forms, such as the bacteria that causes the Bubonic Plague, can kill a person if left untreated. There are many different types of bacteria and they respire using different methods. The two primary methods of bacterial respiration are aerobic respiration…
