Many organisms are found in diverse environments around the world. Some of them consider extreme environments as the cradles of their life: hot springs from volcanoes, extremely salty lake waters or even deep oceans where there is a lack of light or oxygen. But these organisms have their own mechanisms; are already integrated into their genetic material. But there are also organisms that have shown adaptations to certain experimental environments in research, proving that these adaptation mechanisms are not only genetically determined, but can also be triggered when these special functions are needed as a fundamental strategy of survival in the wild. But organisms that live in extreme conditions are not the only ones with the capacity to find strategies to survive. These adaptations can be explored in our own bodies. The organisms discussed in the following paragraph will mostly be single cells or even organic molecules. Since the following aspects of the discussions will focus on cellular functions or strategies for regulating homeostasis. Some organisms, such as extreme thermophiles (Campbell, NA, et. al, 2009), can survive in a habitable environment, which is the acrhaea in the genus Sulfolobus. These archaea can survive and function normally in sulfur-rich volcanic springs, where it can be up to 90 degrees Celsius, lacking in food, and containing a high dose of sulfur. Normally, most organisms would not be able to survive, because the proteins that build our body tissues will change shape under heat (above 90 degrees Celsius), and these shape changes can lead to malfunction. and denaturation of enzymes. (But these Sulfolobus have their special sequencing of genetic information, so their ribosome can induce the...... middle of paper ...... (see Endothelium)3. Duncan, RF and JWB Hershey.
