Many microorganism can tolerate extremes of temperatures how?

'coz most of the microorganisms have MORE cytosine-guanine bond IN THEIR DNA OR RNA which is bounded by three hydrogen bonds as compared to adenine-thymine or adenine-uracil bonds,hence more temp. and energy is required to break the triple hydrogen bonds,hence they can tolerate EXTREMITIES OF TEMP.

yes of course ..\n\nMany of the enzymes in our bodies work best at body temperature. At significantly lower temperatures the substrate molecules do not have enough kinetic energy for the reaction to take place even in the presence of the enzyme. At body temperatures significantly higher than normal, the enzyme will not work well because the kinetic energy from the molecules in the solution containing the enzyme is so high, that the enzyme's shape is pulled apart to he point that the enzyme is not able to properly function. \n\nIndeed the enzyme's structure may be so disrupted or denatured hat the enzyme molecule cannot return to its original shape. Indeed the danger of high fevers stems in large part from the potential damage to enzymes and other proteins from the high temperature

Well, for starters, Temp is important for the catalytic effect, a low temp will slow the reaction, while too high a temp will kill the yeast.  Sugar is the food source for the yeast, so if there is not enough, the yeast wont divide as much.  Water is important of course to provide a comfortable anaerobic environment. Hope that helps you some.

Both speed up at high temperatures and slow down at low temperatures. Photosynthesis does have a maximum cutoff temperature (usually 30 C in temperate plants and I think 40 C in tropical C4 plants).

Few complex life forms we know of can survive exposure temperatures that low for more than a moment. However, if pockets of milder temperatures could be found (thermal vents, well isulated hybernation dens, etc) some life would likely adapt. Life forms that could mature and reproduce in one warm season (such as a plant that produces spores capable of surviving such a harsh winter) would have a great advantage. Plants such as trees woudn't stand a chance, as is true of many things humans and other complex life depend on for food and shelter. \n\nAnother consideration would be the erosion due to lack of any plants capable of maintaining a root system to stablize soil. Between the turbidity from erosion and likelyhood that all rivers would freeze solid through most of the winter, most life in rivers and lakes would become extinct. Since the upper temperature is not much if any higher than what we have now, the average temperatue is much lower. This would concentrate vast amounts of water in the icecaps, possibly enough to greatly increase the salinity of the oceans, which would also see a major drop in temperature. Most marine life is more sensitive to temperatue changes than terrestrial or freshwater life, so a great number of extinctions there also.\n\nSo no, life would not survive other than perhaps a few simple life forms. Even a drop of a dozen degrees in average temperature would be devastating in the long run for life as we know it.

B.\n\nOcean temperatures do not change very rapidly, and most organisms don't require large temperature changes.

Chemosynthetic bacteria, chemosynthetic bacteria can survive without light energy, they can live in dark and inhospitable regions, including the hydrothermal vents of the Pacific Ocean. Around these vents, where temperatures reach up to 350°C/662°F, the chemosynthetic bacteria are the basis of a food web supporting fishes and other marine life including the fairy shrimp

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

Yes, if you take something thats adapt to its enviroment and place it in a different enviroment it will die, or try to find a suitable enviroment. This is only with organisms that are weaker then some and cant adapt fast enough. Often the most simple organism is the strongest, without heating and air conditioning humans would have alot of problems with moving, even from the central united states to the southern states. In the past, thousands of people died from a heat wave that swept accross the US, and the tempuratures werent that high, if you are use to the mid/southern states. But it was in the northern states that it happened.

Archaebacteria include those hearty lil' bastards that love extreme conditions: Hyperthermophiles (live in extreme heat), Extreme halophiles (live in extremelely salty environs, like the Dead Sea), Methanogens (methane-producers), etc.\n\n5 examples:\n\n-Dunaliella salina--an extreme halophile that inhabits the Great Salt Lake in Utah\n-Methanocaldococcus jannaschii--an methanogen that inhabits volcanic vents on the ocean floor\n-Thermus aquaticus--Sulfobale found in sulfur-rish hot springs in Yellowstone Nat'l Park, used for it's polymerase enzymes (Taq polymerase) that function at high heats for use in DNA labs.\n-Thermoplasma acidophilum--a chemoorganotroph that lives in the highly acidic conditions found on self-heating coal refuse piles.\n-Archaeoglobus fulgidis--a sulfate reducing hyperthermophile found near volcanic vents on the ocean floor.\n\n\nEubacteria: these are the "true bacteria."\n\n-Escheria coli--bacteria that lives in the gut of mammals.\n-Derxia gummosa--a nitrogen-fixing bacteria that lives in soil.\n-Acetobacter aceti--a bacteria that metabolizes ethyl acholhol into vinegar, used in commercial vinegar production.\n-Lactobacillus delbreckii--the bacteria used in the production of yoghurt from milk.\n-Synechococcus lividus--a type of cyanobacteria (formerly called blue-green algae), which produce most of the world's oxygen and live in the oceans.

theres a whole bunch of conspiracy theorys on this if you search around.  I found this one article though that was kind of interesting http://archives.cnn.com/2002/WEATHER/05/27/bugs.weather/index.html\n\nif we can use microbes to make medicine why not control the weather with them... really both concepts are pretty crazy but the medicine one is already done.

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

The responses of microorganisms to growth-inhibiting salt concentrations have been studied extensively. In a number of cases, the effects of both salt and sugar stress on the accumulation of individual compatible solutes such as K+ and glycine betaine have been determined. However, only in a few studies have the osmolytes accumulated in salt-stressed cells been compared with those in sugar (nonionic)-stressed cells

you need to try a science website , i know the temp has to be very high. just put your question into a web search.
