What extremophile group does Artemia Salina fall under.?
147333
Artemia Salina are Xerophiles.\n\nOrganisms that thrive in what, for most terrestrial life-forms, are intolerably hostile environments.1 The majority of known extremophiles are varieties of archaea and bacteria. They are classified, according to the conditions in which they exist, as thermophiles, hyperthermophiles, psychrophiles, halophiles, acidophiles, alkaliphiles, barophiles, and endoliths. These categories are not mutually exclusive, so that, for example, some endoliths are also thermophiles. \n\nThe discovery of extremophiles points out the extraordinary adaptability of primitive life-forms and further raises the prospect of finding at least microbial life elsewhere in the Solar System and beyond.2 There is also growing support for the idea that extremophiles were among the earliest living things on Earth.\n\nHere is a good link:\nhttp://www.daviddarling.info/encyclopedia/E/extremophile.html

If you can answer this, you'll be a very famous woman.\n\nThe Ediacaran fauna are a big mystery to us; we don't know how they fit into modern taxonomic groups.  That is, we don't know if they're related to Cambrian forms, or if they represent a collective evolutionary dead-end.  We're in the dark as to their ancestors, as well.  It seems like opinion is falling on the side that they are distantly related to modern groups, but we really don't know; this is very much an active area of research.

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.

Wood-boring bivalves of the family Teredinidae (commonly called shipworms) are known to harbor dense populations of gram-negative bacteria within specialized cells (bacteriocytes) in their gills. These symbionts are thought to provide enzymes, e.g., cellulase and dinitrogenase, which assist the host in utilizing wood as a primary food source. A cellulolytic, dinitrogen-fixing bacterium, Teredinibacter turnerae, has been isolated from the gill tissues of numerous teredinid bivalves and has been proposed to constitute the sole or predominant symbiont of this bivalve family. Here we demonstrate that one teredinid species, Lyrodus pedicellatus, contains at least four distinct bacterial 16S rRNA types within its gill bacteriocytes, one of which is identical to that of T. turnerae. Phylogenetic analyses indicate that the three newly detected ribotypes are derived from gamma proteobacteria that are related to but distinct (>6.5% sequence divergence) from T. turnerae. In situ hybridizations with 16S rRNA-directed probes demonstrated that the pattern of occurrence of symbiont ribotypes within bacteriocytes was predictable and specific, with some bacteriocytes containing two symbiont ribotypes. However, only two of the six possible pairwise combinations of the four ribotypes were observed to cooccur within the same host cells. The results presented here are consistent with the existence of a complex multiple symbiosis in this shipworm species.

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.

Yeah... most of them are strange and dangerous creatures with a horrible face...\nA unique endemic biota formed in the lake preceding modern Black Sea during millions years of its isolation from the Ocean. Most of the species inhabiting freshwater Sarmatian Sea-lake are extinct now, whereas few of them managed to adapt to the changing environment and have survived to this date in the deep deep water - mostly those that managed to escape the rise in the salinity level in river estuaries...\nHope this will help!Good luck!

Many archaea colonize extreme environments.\nThey include hyperthermophiles, sulfur-metabolizing thermo-\nphiles, extreme halophiles and methanogens. Because extrem-\nophilic microorganisms have unusual properties, they are a\npotentially valuable resource in the development of novel bio-\ntechnological processes. Despite extensive research, however,\nthere are few existing industrial applications of either archaeal\nbiomass or archaeal enzymes. \nCultivation methods, recent achievements in genomics, which are of key importance for the devel-\nopment of new biotechnological tools, and the application of\nwild-type biomasses, engineered microorganisms, enzymes\nand specific metabolites in particular bioprocesses of indus-\ntrial interest.\n\nA major limitation to the industrial application of archaeal en-\nzymes and metabolites is the low productivity of the fermenta-\ntion processes as a result of low growth rates and low biomass\nyields. To overcome these limitations, attention has been fo-\ncused on studying the physiology of archaea of biotechnological \ninterest and on designing bioreactors and bioprocesses that\nincrease productivity. Because of the unconventional environ-\nmental conditions needed for the cultivation of extremophiles,\ncontamination problems are minimal. Therefore, a continuous\nculture approach has been widely adopted.\n\nhttp://72.14.203.104/search?q=cache:ZMgRQbu0KPEJ:www.biotechinstitute.org/resources/pdf/yw14_2.pdf+applications+of+archaea+in+biotech&hl=en&gl=us&ct=clnk&cd=3&client=firefox-a  for more info

Archaebacteria (är´´kēbăktĭr´ē) , diverse group of bacteria (prokaryotes), sometimes called the archaea and considered a major group unto themselves. Archaebacteria are contrasted with the Eubacteria, from which they differ biochemically in the arrangement of the bases in their ribosomal RNA and in the composition of their plasma membranes and cell walls. There are three major known groups of Archaebacteria: methanogens, halophiles, and thermophiles. The methanogens are anaerobic bacteria that produce methane. They are found in sewage treatment plants, bogs, and the intestinal tracts of ruminants. Ancient methanogens are the source of natural gas. Halophiles are bacteria that thrive in high salt concentrations such as those found in salt lakes or pools of sea water. Thermophiles are the heat-loving bacteria found near hydrothermal vents and hot springs. Many thermophiles are chemosynthetic (see chemosynthesis), using dissolved sulfur or other elements as their energy source and iron as a means of respiration. Archaebacteria emerged at least 3.5 billion years ago and live in environments that resemble conditions existing when the earth was young.

There is no answer to this question.\n\nNot all  living organisms adapt under environemental stress. We can see this simply by looking at widespread organisms like leopards. Despite living everywhere from tropical deserts to rainforest to temperate alpine tundra they remain completely indistinguishable form one another. Although a desert leopard suffers from serious environmental stress in terms of water and prey availability and a mountain leopard suffers from cold and a forest leopard suffers from fungal diseases and so forth the organisms don't adapt at all. It is a generalist species and it remains a generalist with no specific adpations to environmental stress.\n\nWe can even prove experiementally that not all species dapat to environmental stress. Simply grow a perti dish fill of different species of bacteria and let it dry out. As the water stress increases most organisms will either die or become dormant. There is no evidence whatsoever of adaptation over any time scale.\n\nSimilarly not all porganisms will flee. Most will simply die, hibernate or scrape through.\n\n\nWhat a dumb question.

The very oldest species on Earth are the cyanobacteria, which seem to have been around virtually unchanged for nearly 4 billion years. This is based on fossils of that age that have been compared under high-powered microscopes to existing species of these bacteria. Other bacteria that are about as old are the archaea, which thrive in acidic, high- temperature, or high-radiation environments. \n\nAnother remnant of ancient organisms includes the stromatolites, mounds of algae and bacteria that today grow in the Bahamas, Shark's Bay Australia, and a few other limited environments. They have been around, also largely unchanged, for over 3 billion years and at one time were the Earth's dominant form of life. \n\nOn the animal side of things, the brachiopod Lingulaa is probably the oldest, having existed nearly unchanged for over 500 million years, and the horseshoe crab (limulus) has been on the planet for several hundred million years, too. Since the average "lifespan" of a species is only a few million years, having such ancient species around is very impressive. \n\nA good book about the earliest life is "Cradle of Life" by J. William Schopf. He is one of the premier scientists doing this sort of research. At a more advanced level, he has edited two scientific books, "Earth's Earliest Biosphere" and "The Proterozoic Biosphere", which should be in your university's geology or science library.
