Life Of Extreme Conditions : Planet Earth

These extreme factors contribute to create a highly biodiverse ecosystem (Bamfield Marine Sciences Centre, 2013).

<b>Introduction</b><br>Think of a world which existed 290 million years ago. As you look out over the terane in front of you, you think that you are on an alien planet. You see volcanoes spewing ash and lava. Beside them is the ocean which is swarming with many different species of echinoderms, bryozoans and brachiopods. As you look down onto the sea floor you are amazed at the countless number of starfish and urchins. Some animals leave you can't even describe and you have no idea even what phylum they belong to. This is a world at its height in diversity of oceanic species. Millions of wonderous species existed at this time in the ocean and most of them will never appear again in earth's history. In the geologic time scale, a million

Finally there is the Hyperthermophiles. Found in very hot temperatures such as hydrothermal vents in deep oceans. With this said, the two microorganisms that I worked with would be known as Mesophiles. Both of these microorganisms grow on or in the human body. They prefer moist heat that is body temperature. I made an incubation box to help mimic the temperatures needed. Typically trying to maintain the temperature of thirty seven degrees Celsius.

For millions of years’ bacteria have been surviving to their environments and been at war against other microorganism. This wars have lead them to creating an unstoppable arsenal of weapons they can use to survive. Unlike virus that need a host cell to survive, bacteria can survive anywhere since they can share their DNA with each other. This allows bacteria to survive in places like radioactive waste, zero oxygen environments, and even in absolute darkness. Unlike human beings who are born with a specific genetic code, bacteria have the capability of changing that code. Bacteria have three methods of evolving themselves in order to survive the harsh is of conditions. The three methods are called horizontal gene transfer. The first is Transformation, but some pathologists call it the “Funeral Grab”.

Extremophiles are organisms that have been discovered on earth that survive in environments that were thought to not be able to sustain life

Earth as it was known is no more An infectious parasitic hivemind known as ‘Rhadamanthus’ arrived on Earth and began assimilating its lifeforms, threatening to end everything. In a last ditch effort to preserve humanity, a fleet of ark ships - each loaded with cryogenically preserved humans, plants, and animals- was sent to explore the deepest reaches of space.

There are tiny creatures called extremophiles that live here. Inside the creature's cell membrane, they have specially adapted structures. These structures pump out acidic substances allowing these microorganisms to thrive.

There is life all around the planet, even in extreme habitats. How it is possible for organisms to survive in such extreme conditions? It is possible to have life out of Earth? How this life could be? To try answering these questions, it is necessary to look back to Earth’s history and its current environments and conditions, as well other places in the solar system, searching for tips in the complexity of organisms adapted to the extreme conditions for life beyond Earth.

The extraordinarily resilient bacterial species of Bacillus pumilus has been observed to withstand inexorable quantities of ultraviolent radiation and extreme temperatures. During Curiosity’s launch, scientists meticulously sterilized the launcher and probe so as to eliminate Earth contaminants. However, several hundred strands of these invincible bacteria could have survived the decontamination process. Although it is miraculous for even the most tenacious of microbes to survive the excruciatingly high levels of Ultra C radiation past the Van Allen’s belt, scientists are suspicious that B. pumilus may have survived a seven month trek with outrageously low temperatures and ghastly high quantities of radiation. A United Nation Outer Space Treaty specified that only 300 microbial endospores per meter could exist in the landing site. These rather stringent guidelines provoked agitation in some astronomers, as exceeding the limit would void Curiosity’s mission warrant. This article will

As scientists, particularly astrobiologists, learn more about life on Earth our perception of is habitable is changing 7. The discovery of life living my mid ocean ridge geothermal vents in the 1970’s is a classic example of this. Before it was thought that life could not exist without light from the sun. By these geothermal vents organisms exist, completely cut off from other ecosystems. These vents are often thousands of kilometers below sea level and most receive no light from the sun. They also exist under a high pressure environment. Some of these organisms, or extremophiles, are complex organisms that feed off the minerals emitted from the vent in a process called

According to researchers, tardigrades have the power to survive close to anything, and they will most likely outlive humans. A study performed in July of 2017 found that the tardigrade, a one millimeter sized microorganism, has the outstanding ability to survive countless different temperatures. They can be found in any body of water or on plants such as moss and can survive temperatures from extremely cold heights to the torrid heats of a desert and can even be spotted in deep oceans. Scientist in japan have tested and confirmed something

Hypersaline environments constitute typical examples of environments with extreme conditions due to their high salinity, exposure to high and low temperatures, low oxygen conditions and in some cases, high pH values. Bacteria and Archaea are the most widely distributed organisms in these

While thermal vents and hot springs are considered to be some of the most extreme environments on Earth, several organisms are able to thrive in these hostile locations where most life would perish. Among these are thermophiles and hyperthermophiles. While the two share similar adaptations to survive in these extremes, they differ in their temperature growth optimum. Hyperthermophiles can grow optimally up to 105°C, whereas thermophiles are classified as growing between 50°C and 70°C. At such extreme temperatures, proteins lacking the necessary adaptations undergo irreversible unfolding, exposing the hydrophobic cores, which causes aggregation . Thermophilic proteins have several adaptations that give the protein the ability

As we should know, there are multiple actions that can occur in this marine-type biome that can be described in every ideas. Most people and scientists failed to understand life that occurs in the ocean, this is because marine plants and animals live in territories where humans can occupy on. Even though certain areas or depths of the ocean is unexplored, it is the habitat of 230,000 known species. There are also other oceans that are not found in Earth or within the Solar System because these oceans have different mixture of elements and compounds, which are called extraterrestrial oceans. So far, the only extraterrestrial liquids that is found within the Solar System (which is made ethane and methane) is Saturn’s largest moon known as “The Lakes of Titan”. Otherwise, there are ocean planets that exist outside the Solar System, which are considered exoplanets that the whole surface is completely made out of

A photograph of Earth reveals a great deal, but it does not convey the complexity of our environment. Our environment (a term that comes from the French environner, “to surround”) is more than water, land, and air; it is the sum total of our surroundings. It includes all of the biotic factors, or living things, with which we interact. It also includes the abiotic factors, or nonliving things, with which we interact. Our environment includes the continents, oceans, clouds, and ice caps you can see in the photo of Earth from space, as well as the animals, plants, forests, and farms that comprise the landscapes around us. In a more inclusive sense, it also encompasses our built
