Before the 1970’s, people thought that all life on earth derived from energy provided by the sun. As human beings, yes, it is essential for our bodies. We absorb sunlight through our skin and produce essential vitamins and minerals that our bodies need. The sun also warms our planet making living conditions tolerable. Without the sun our planet would be extremely cold and impossible to live on. Plants and animals also need the sun for existence. In fact, humans, animals and plants need the sunlight, for it is the main source for the creation of our food. Imagine living in temperatures as high as 200°F or as low as 100° below zero. Or consider jumping into a pool of bleach or gasoline. These conditions would be fatal to the average …show more content…
These organisms need temperatures to be at least 113°F for reproduction. There are organisms that require even hotter temperatures, as hot as 176° F. These organisms are referred to as hyperthermophiles. No multicellular animal or plants have been found to tolerate these types of conditions. These discoveries were made in the late 1960’s. Extremeophiles can be found on volcanic hydrothermal vents located on the bottom of the ocean floor. The most heat resistant of these microbes, Pyrolous fumarii, grow in the walls of the hydrothermal vents, also known as black …show more content…
All living things are made up of enzymes and proteins that break down when the organism is exposed to extreme life threatening conditions (visualinsight.net). Extremophiles are believed to have adapted to these extreme conditions because of “heat stress proteins.” Scientists have discovered special molecules, also known as “molecular chaperons,” that are produced when the organism is exposed to deadly conditions. These molecules are activated and will repair the proteins damaged by stressful encounters in the same way a human will develop a fever to fight off infection. The fever activates these “savior proteins” and healing
It is hard for our new generations to live with no light. They have been used to artificial light since they were born. Even though, in the older times people had more children but they still used candles. Cutting down completely on all artificial light would be great, but that’s impossible to happen. Technology is going to keep improving. However, if we don’t stop and try to cut down on some of the lighting we use, there will be consequences. Our upcoming generations might not be able to see stars in the sky anymore.
Cascade High School’s (in Cascade, Idaho) research lab projects are student taught – passed down from one student to the next each year. Thermus Aquaticus (TAQ) is a research lab project focused on identifying a thermophilic bacterium found in a local hot spring, Vulcan Hot Springs. The polymerase gene in bacteria species, mainly Thermus aquaticus, has proven useful in polymerase chain reactions (PCR), an important reaction in genetic and forensic sciences. The Vulcan bacterium grows at a higher temperature than Thermus aquaticus; the polymerase gene from Vulcan may prove to be more useful than those currently available.
The 1970’s was an era of political, environmental, and technological awareness. This era provided the American people with information and inventions that would positively shape the future of the United States. Awareness brings about optimistic thinking and change. This is exactly what happened in the 1970’s. Political awareness brought about accountability for the government and politicians. Environmental awareness brought about consumer and governmental accountability in energy usage. Inventions in the 1970’s were the platform for technology age that Americans currently rely on daily.
The 1950s saw a period of extensive contentment within postwar America. A majority of the population adapted to the modern suburban lifestyle that emerged within this time period. They bought houses, started families, got steady jobs, and watched the television while complacently submitting to the government. Although fairly monotonous, this sort of lifestyle was safe and secure many Americans were ready to sacrifice individuality for a sense of comfort. There was a minority, however, that did not quite accept this conservative conformity that had swept across the nation; some of these people took the shape of artists and writers. During the 1950s, what became known as the "Beat Generation" inspired the challenging of and rebelling against conventional America.
Bacillus anthracis is a non-motile elongated rod-shaped bacterium that will generate dormant spores with or without oxygen. When the spores are exposed to high levels of carbon dioxide and warmth they adjust into a ro...

In the United States in the late 20th century, there were liberals and conservatives. Liberals generally favored government intervention to help needy and conservatives generally favored allowing the free market, private organizations, and individuals to do that. During the 1960s and 1970s, democrats and Republicans began having different agendas as compared to the 1940s and 1950s when the two parties had aimed for both containing communism. During the 1970s events such as the Iran hostage crisis and oil crisis and Watergate weakened the public’s faith in the federal government . During the 1970s, conservatives felt as though the Great Society had made the problem of poverty worse.
A drug is a medicine or other substance that has a physiological effect when ingested or otherwise introduced into the body. Many people use drugs without realizing how addictive they can become. During the 1960s and 1970s drugs had a huge impact on the people and as years went on they became more and more dangerous to the point where marijuana, and LSDs were becoming popular and the group most affected were teenagers.
All You Need Is Hate If life in the 1960s was a collective journey to the Underworld, then it is terrifying to notice how many of us have failed to come back. (Marshall Berman, The Sixties)
Although the experiment produced varying results amongst the pairs of test tubes in each of the water temperatures, the Mean calculations proves that the temperature rising will increase the amount of kinetic energy in the movement of the Phosphate and Lipids in the cell membrane as well as breaking the hydrogen bonds of the proteins in the cell membrane,
"Photorhabdus and Xenorhabdus bacteria therefore engage in both pathogenic and mutualistic interactions with different invertebrate hosts as obligate components of their life cycle." (Goodrich-Blair and Clarke)
Different types of bacteria have different range of temperature they are able to survive. They are generally divided into three types: psychrophiles, mesophiles and thermophiles. Psychrophilic bacteria are able to survive in low temperatures ranging from about -10 to 20°C while thermophilic bacteria are able to thrive in high temperatures ranging from 40 to 75°C. These two types of bacteria are also known as extremophiles due to their ability to survive in extreme conditions. Mesophilic bacteria are bacteria that thrive in temperatures ranging from 10 to 45°C and usually have an optimum growth temperature of about 37°C (M. Furlong, n.d.).
Life according to scientists is “the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death, also the way of life of a human being or animal.”("Life,”) In order for one to have life, one must have the nine characteristics to be considered a living thing. These nine characteristics are; all living things are made up of cells, living things are able to reproduce, living thing use energy, maintain homeostasis, respond and adapt to the environment, grow and develop, have a life span, evolve over time, and are interdependence. All of the nine characteristics have one thing in common, something that is needed for all living things to use, even if they do not know it. This beautiful thing that all living things should value is photosynthesis. Without photosynthesis there wouldn’t consist humans, animals, insects, and most importantly life!
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
We need the sun for everything; food, transportation, education, and just to live. The sun negatively affects us in our daily lives because our skin is sensitive to the sun. This means that we are prone to burn. A way to protect our skin is with sunscreen. The short-term effect of not wearing sunscreen when exposed to the sun is you can get a painful rash or peeling of skin can occur. Long-term effects of not protecting yourself from the sun can be that it changes your DNA or gives you skin cancer. It changes your DNA by radiation smashing into you skin. The reason why this is so dangerous is because the DNA will now instruct the skin to fix itself because of the radiation, but the instructions would have been changed. It can also speed up
