Hi friend,\nSince your question is a bit technical, i assume that you are from a microbiology/biochemistry background. Hence the answer too is given with technical details. If you can't digest it, i may be able to give a simpler explanation. Just leave a comment alongside the answer.\nIt is also assumed that ur querry is about rRNA differences between EUBACTERIA and Archaea.\n\nGenerally speaking, unlike Bacterial RNA, archaean  RNAs are not capable of catalysis in the absence of other enzyme components. The structural basis of this deficiency must be in the  differences in  bacterial and archaeal sequences or higher order structure. \n    Secondary structure in Archean RNA contains all but one helix present in that of Bacterial structure, the 2 bp helix P11. This structure is adjacent to a large region in which the structure remains unknown even in bacterial RNase P RNAs. \n\n           In Eubacteria, rRNA modification is achieved exclusively by site-specific enzymes while in archaea and eukaryotes the formation of 2-O-methylriboses and pseudouridines is guided by numerous snoRNA that direct a catalytic machinery to the target sites on the pre-rRNA.        \n         \nMore over the GC content of the paired stem regions of the 16S rRNA genes in Archaea is very high and it correlates somewhat with the high  temperatureconditions they grow (or evolved in)\n\nThat's what i know of the differences. Hope thats clear,\nBye..

Depends on what kind of bacteria. Some bacteria release CO2, some are phtosynthetic and release O2, some release NO-, NO2, NO3, or NH3. Most likely, the iron rusts.

Well, not to sure about your question... so I'll do my best.\n\nPositive interactions between microbes would be ones that cause a general benefit.  Like a bacteria excreting a certain amino acid that another bacteria would need in order to survive.\n\nNegative interaction would be microbes causing a detriment to each other.  Pencillium notatum generates an antibiotic naturally, causing a harmful environment to some bacteria.\n\nSymbiosis is two organisms living together in harmony.  If you refference Margulis's endosymbiont hypothesis, a large microbe, say an amoeba engulfs a photosynthetic bacteria.  The amoeba provides a safe location for the bacteria, and the bacteria provides energy to the amoeba.\n\nAntagonism... not to sure about this one.  Probably something of a parasitic interaction.

I just checked out the site. It is total crap. Water does not kill Pathogens, and you cannot change the bond angle of water no matter how hard you boil it, freeze it, or whatever. Save your money.

truthfully, it hasn't been completely labeled as  beneficial. yes, it does have calcium, vit d, etc, but some studies actually show that our bodies don't digest them properly.  if anything, it keeps you hydrated. humans are kinda strange though... do you realize that we are the only species that drinks milk long after infancy? lol not to mention, another species breast milk. yum!

thermoacidophiles and methanogens are types of archaebacteria and there is one more type called halophiles.\n\n1. thermoacidophiles : these are temperature and acid-loving archaebacteria.these organisms grow at high temperature of 55 degrees celius to 59 degrees celsius and a pH of 2.the cells undergo lysis at neutral pH.thermoplasma ,thermoproteus,sulfolobus are the common thermoacidophiles.in these thermoplasma and thermoproteus are pleomorphic(spherical to filamentous) common in pile of burning coal refuse. the genus sulfolobus is facultative autotroph growing better at 70 degrees celsius to 87 degrees celsius and at a pH of 2. in nature these are predominant in acidic hot springs,sulfur springs and in hot acid soils.a specialized cell membrane in these bacteria composed of a monolayer of long chain hydrocarbons connected at both ends to glycerol by other linkage enable them to grow in hot-acid environment.\n \n2. methanogens: they are the methane-producers.the methanogens are obligant anaerobes occur in marshy areas like swamps,ponds,lake mud,among the microorganisms in the rumen of cattles and anaerobic sludge digesters in sewage treatment plants.these bacteria convert fermentation products of other bacteria like CO2 , H2,formic acid and acetic acid into methane and CO2 or only methane.\n\n3.halophiles: these are salt-loving or halophilic archaebacteria.they occur in salt lakes and salty fish.e.g. halococcus and halobacterium.these require 17 - 23 % NaCl for good growth.if the concentration of NaCl falls below 10%,the cells lyse.these organisms contain red or orange pigment called bacteriorhodopsin.the bacteriorhodopsin accumulate as patches in the cytoplasmic membrane and protect the cell against the damaging effect of sunlight. the pigment also utilises the light energy to run their metabolic activities by producing ATP . however,these cannot convert CO2 to sugars as in photosynthesis.

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

Archaea (AmE [ɑɹˈkiə], BrE [ɑːˈkiːə]; from Greek αρχαία, "old ones"; singular Archaeum, Archaean, or Archaeon), also called Archaebacteria (AmE [ɑɹkɪbækˈtɪɹɪə], BrE [ɑːkɪbækˈtɪəɹɪə]), is a major division of living organisms. Although there is still uncertainty in the exact phylogeny of the groups, Archaea, Eukaryota and Bacteria are the fundamental classifications in what is called the three-domain system. Like bacteria, Archaea are single-celled organisms lacking nuclei and are therefore prokaryotes, classified as Monera in the alternative six-kingdom taxonomy. They were originally described in extreme environments, but have since been found in all types of habitats.\n\nA single organism from this domain has been called an "archaean." Furthermore, this biologic term is also used as an adjective.

I am not sure whether they are chemoaututrophs, but the extreme halophiles are gram (-), like halobacterium, natronobacterium, halococcus, natrococcus, haloferax and haloarcula.  I am not sure if that helps at all.

E)  All of them.\n\nA)  Cows don't breathe it in, and it doesn't come from the water so it has to come from the diet.\nB)  Same as A\nC)  While it is true that phosphorous is in our soil, I would argue that the use of detergents and fertilizers are the major problems with phorphorous contaminating our lakes.\nD)  DNA is made of bases (nucleotides) attached by a "sugar phosphate backbone".  If bases are the rungs of a ladder, the sugars and phosphates make up the sides of the ladder.

Archae are bacteria. Not Bacteria, but bacteria with a small b. There are no known live pathogens becasue they live in extreme conditions such as high temp, high pressure etc....\nThey are just as evolved as any other life form, and bear in mind disease is caused by the bodies reaction rather than by the causative agent.

I agree with Climecita. The crab also has wonderful medical implications as well. (I did not check the links) The crabs blood is blue and it contains one of the worlds strongest antibacterial compounds on the earth. They actually have farms where they harvest the blood of these creatures. Oh and for one more note their blood is mixed into the bags that hold our blood when we dontate, or get a transfusion.

Archaea are associated with being extremeophiles - that is living in an extreme environments where other bacteria are thought to be unable to live- such as very hot, acidic, or very cold. They are also thought to be some of the most ancient organisms on earth.  A good source of info and pictues is at http://www.theguardians.com/Microbiology/gm_mbm04.htm\n\nBacteria is now in a different domain than the archeaea.  This is the " classic" bacteria we think of and have known about for quite awhile. You can learn more about bacteria from http://www.ucmp.berkeley.edu/bacteria/bacteria.html if you like.
