Uhhh.... isn't bacteria a single-cell organism?\nPlease be more specific.

Bacteria are prokaryotic, meaning 'without nucleus'. The basic bacteria has a cell membrane, which holds in its cytoplasam and genetic material. The bacteria holds lots of ribosomes for creating proteins, which are ever so important in a living organism. Bacteria do not have a cell wall, this is plant cells (eukaryotic) only. Some bacteria have tiny hairs covering the body called silia aiding in movement. Other have a single hair, or maybe two, this is called a flagellum. I typed this fast so spelling may be off, but the information is correct.\n\nthefeistyguy

*Digging out my encyclopedia* The first bacteria were observed by Antony van Leeuwenhoek in 1683 using a single-lens microscope of his own design. The name bacterium was introduced much later, by Ehrenberg in 1828, derived from the Greek word βακτηριον meaning "small stick". Louis Pasteur (1822-1895) and Robert Koch (1843-1910) described the role of bacteria as conveyors and causes of disease or pathogens.\n\nOriginally the bacteria were considered microscopic fungi (called Schizomycetes), except for the photosynthetic cyanobacteria, which were considered a group of algae (called Cyanophyta or blue-green algae). It was only with the study of detailed cell structure that it was realized they formed a fundamental group, separate from the other organisms. In 1956 Copeland gave them their own kingdom Mychota, later renamed Monera, Prokaryota, or Bacteria. During the 1960s the concept was refined and bacteria (now including cyanobacteria) were recognized as one of two major divisions of the living world, together with the eukaryotes. Eukaryotes were generally believed to have evolved from bacteria, later from assemblies of bacteria.\nhttp://www.aaaah.org/wiki/en/ba/Bacterium.htm\nBacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts. Their cell structure is further described in the article about prokaryotes, because bacteria are prokaryotes, in contrast to organisms with more complex cells, called eukaryotes.\nhttp://en.wikipedia.org/wiki/Bacteria

Archaebacteria are the oldest living organisms on earth. They are unicellular. Archaebacteria are found in very harsh conditions (such as at the bottom of the sea or in volcanic vents). This is thought to be because the early Earth’s atmosphere was filled with poisonous gases and was very hot – nothing could survive except the archaebacteria. These slowly gave way to modern organisms when the Earth’s conditions settled down and oxygen was introduced to the atmosphere.\n\n    There are three phyla of archaebacteria. The methanogens are characterized by their ability to harvest energy by converting H2 and CO2 into methane gas. They (and all archaebacteria) are obligate anaerobes, meaning they cannot live in the presence of oxygen. They are found in marshes and in the intestinal tracts of humans and some animals (cows, for example).\n\n   The second phylum is the extreme halophiles. These organisms are names because they are salt-loving. Though salt kills most bacteria, it helps the extreme halophiles to thrive. They are found in the Dead Sea, the Great Salt Lake, and other areas with a high salt content.\n\n   The third phylum is the thermoacidophiles. These bacteria are found in extremely acidic conditions and in areas with very high temperatures. They can survive in areas with temperatures as high as 230 degrees Fahrenheit and with pHs below 2 (hydrochloric acid, which is incredibly strong, has a pH of 1). These locations include volcanic vents and hydrothermal vents (cracks in the ocean floor where scalding water leaks out).\n\nThe eubacteria are more complex, and common, than the archaebacteria. It is the eubacteria that most people are talking about when they say bacteria, because they live in more neutral conditions. They can be found everywhere around us – in our bodies, our food, etc. There are four phyla of bacteria, some of which are divided into subgroups.\n\n   Cyanobacteria are photosynthetic, like plants, which means that they use the sun’s energy to make food for themselves. They are thought to be the second organisms in existence, because they give off oxygen as a byproduct. This allowed aerobic organisms (ones that need oxygen to survive) to develop. They are found in the water and were once thought to be blue-green algae (however, they lack a membrane-bound nucleus and chloroplasts).\n\n   Spirochetes are gram-negative (a gram stain is a technique for classifying bacteria), spiral-shaped, and heterotrophic. Some of them live in the presence of oxygen, others don’t. They may be parasitic, living symbiotically or free-living. \n\n   Gram-positive bacteria are not all gram-positive, despite the name. They are grouped together due to other similarities. This phylum includes the strain of streptococcus bacteria that causes strep throat. It also includes the bacteria that produces yogurt, by growing and fermenting in milk (producing lactic acid). These bacteria also produce many of our antibiotics.\n\n   Proteobacteria is one of the largest phyla of all the bacteria. Many are gram-negative. They are divided into several subgroups, such as enteric bacteria, chemoautotrophs, and nitrogen-fixing bacteria. The enteric bacteria live mainly in intestinal tracts, like E. Coli. The chemoautotrophs oxidize chemicals in minerals to obtain energy. The nitrogen-fixing bacteria are essential to many ecosystems – one type converts the unusable nitrogen in the atmosphere to ammonia, the form plants can use most easily.

Yes and it is on Mars! No, this isn't a joke, it's true there's bacteria there. That's life. But if you meant intelligent life, that's another story. I'm guessing there is, but it's very possible that these beings don't know of our existence or possibly know of us but would rather avoid us. Either way, is within the realm of possibility.

Microbiologists also classify bacteria according to whether or not they require oxygen to survive. Bacteria that require oxygen are called aerobic bacteria, or aerobes. Bacteria that live without oxygen are called anaerobic bacteria, or anaerobes. Both aerobes and anaerobes can be either phototrophic or nonphototrophic. Can live in the human body or in the enviroment

Depends on where you think man started, and on your definition of Bacteria. In this case I'll assume that you mean the small beings which occasionally causes diseases and the like.\n\nEvolution: Creatures would not exist. Life would not exist. We'd just be that chemical soup... without the chemicals.\nCreation: We'd probably be less plagued with disease and decay as we are now. This wouldn't destroy Newton's Third Law (all things are subject to decay, or something to that effect), just make it less so in the case of life.\nThat spaghetti monster: I have no clue. Maybe the spaghetti dude wouldn't be so... uh... tasty?\n\nI could be wrong.

If you're referring to spontaneous generation.  He had a contest with Felix Pouchet who believed in spontaneous generation.  Pasteur bent the necks of his flask so that dirt would be caught before it reached the broth and no bacteria arose.  This showed that bacteria were carried in dirt.

Bacteria die when they are subjected to higher temperatures.  The only thing that can survive in really high temperatures(around 100 C) are organisms from the Domain Archaea...extremophiles.

Hehe, you'll love this one:\n\nSpecies 2-9-3, which is a bactirum of the genus Bacillus, preserved itself in salt, and was made to life again after 250 million years :)  Typical of this genus.  In fact, it was found within the brine of salt dug up on a dig.\n\nDate report came out:  19 October 2000 \n\nThink that about covers your question :)

Hey..are you trying to get your homework done here !! OK seriously speaking.......... The Proteobacteria are a major group of bacteria. They include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, and many other notable genera. Others are free-living, and include many of the bacteria responsible for nitrogen fixation. The group is defined primarily in terms of ribosomal RNA (rRNA) sequences, and is named for the Greek god Proteus (also the name of a bacterial genus within the Proteobacteria), who could change his shape, because of the great diversity of forms found in it.\n\nThe proteobacteria are divided into five sections, referred to by the Greek letters alpha through epsilon, again based on rRNA sequences. These are often treated as classes. Gamma Proteobacteria are paraphyletic to the Beta Proteobacteria.\n\nThe Gammaproteobacteria comprise several medically and scientifically important groups of bacteria, such as the Enterobacteriaceae, Vibrionaceae and Pseudomonadaceae. An exceeding number of important pathogens belongs to this class, e.g. Salmonella (enteritis and typhoid fever), Yersinia (plague), Vibrio (cholera), Pseudomonas aeruginosa (lung infections in hospitalised or cystic fibrosis patients).\n\n\nHope this help :)

Live bacteria seems unlikely. Bacterial spores, no problems.\n\nYou would have more luck trying to isolate fungi.

They are all prokaryotes, some may have a thick cell wall made of peptodiglycan.  They can live in extremely acidic, basic, hot, cold, salty, or wet environments.
