How many “chainobeads” was your enzyme able to make per minute in the 60 – 120 second interval? Our enzyme was able to make 49 chainobeads in the 60-120 intervals. 3. Did your enzyme's rate change over time? How does this compare to a real enzyme?
Many people who were in the towers died that day, but scientists still have not figured out how the towers finally collapsed. They still wonder whether it was a big fire or an unknown chemical reaction in the towers. Christian Simensen, a Norwegian scientist, thinks he knows how the Twin Towers collapsed and it is the best explanation. At a technology congress in San Diego yesterday, he proclaimed the collapse to be a chemical reaction. According to him, the melted aluminum of the airplane dripped through the two skyscrapers and came into contact with hundred liters of water.
Bacteria also live in plants, animals, and have flourished in manned space vehicles. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water. Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes. Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles. Some of the most deadly diseases and devastating epidemics in human history have been caused by bacteria.
The Chinchorro peoples existed around 2,000 years before the Egyptians. They lived on the coast of Chile and Northern Peru. The Chinchorro mummies, which have remained preserved in Chile for more than 7,000 years, are now under threat from increased levels of moisture. Humid air is allowing bacteria to grow, causing the mummies' skin "to go black and become gelatinous”. The rapid deterioration began within the past 10 years, and has affected some of the 120 mummies that are housed at the University of Tarapacá’s archaeological museum in the northern port city of Arica.
In some fracturing jobs—like those in the Marcellus Shale in Pennsylvania and New York—more than 40,000 gallons of fracturing chemicals, with no company disclosure of the chemical constituents, can be used at a single well. Because the process is exempt from most federal oversight, it is overseen by state agencies that are spread thin and have widely varying regulations. A recent report by the Ground Water Protection Council revealed that only four of the 31 drilling states it surveyed have regulations that directly address hydraulic fracking and that no state requires companies to track the volume of chemicals left underground. One in five states doesn't require the concrete casing used to contain wells to be tested before hydraulic fracking. Approximately one‐third of the millions of gallons of water used in fracking returns to the surface, where it is either reused or trucked to treatment plants.
AP Biology Chapter 27 Lecture Notes Prokaryotes and the Origins of Metabolic Diversity I. The World of Prokaryotes A. They’re (almost) everywhere! An overview of prokaryotic life 1. Prokaryotes dominate the biosphere. Their biomass is at least 10 times greater than all eukaryotes.
One resource that is at high risk of being contaminated due to fracking is water. The U.S Environmental Protection Agency (EPA) estimated that up to 140 billion gallons of water are used for 35,000 wells each year. Fracking procedures are even excluded from the safe drinking water act of underground injection controls and regulations except when diesel fuel is being used. That means these companies that perform fracking procedures avoid using diesel so that we have no idea what they’re putting in to the ground. Even some states allow fracking to be exempt from state water use regulation, an agreement limiting large water withdrawals; despite the fact that each fracking well uses up to five million gallons of locally sourced water.
Atlantic coast and in northern Alaska. The lifted ban was aimed at increasing the United States' energy independence and reducing foreign imports so that it would not need to rely so heavily on other countries for energy supplies. The U.S. Atlantic coast could hold as much as 37 trillion cubic feet of gas and 4 billion barrels of oil, the U.S. Geological Survey estimates. But less than a month later, the BP-leased Deepwater Horizon rig sank about 50 miles (80 kilometers) southeast of Venice, Louisiana. President Obama recently announced during his weekly address that no permits for drilling new deepwater wells will be issued until a 30-day safety and environmental review of all deepwater operations in the Gulf of Mexico has been completed.
There were only two tests conducted the the operation but those tests provided the information necessary to construct the nuclear navy and radiology used to treat cancer patients. Many people look at the Manhattan Project as a terrible event where the United States tried to eliminate millions of people, but the fact is that the technology was also used for saving lives. These tests were the first that an invited audience could attend. The two tests were; Able, conducted 520 feet in the air on July 1, 1947 and Baker, detonated 90 feet underwater by the new nuclear navy on July 25, 1947. A third test, Charlie was scheduled to detonate underwater but was cancelled after the navy's incapability to decontaminate the Baker ships.
Areas around the world known as “Dead Zones” are being reported as “areas so low in oxygen that fish and other sea life cannot survive (Oceans Where Fish Choke. November 30, 2010).” These areas are accosted with highly populated coastal areas that are being overfished and have rich nutrient run off coming from land causing massive decline in phytoplankton. Biological Oceanographers worldwide study dead fish that continue to surface on shore by searching for a solution to the problem. Many believe the zones are created due to climate change; however, it is more logical that the constant drain off of the high nutrients is feeding the dilemma. Low oxygen levels increase stress on fish.
