Deep Sea High Temperature
600 wordsts, and biochemical pathways. In comparing the organism 60 % of M. jannaschii's coding regions did not correlate with the known sequence database. 40 % of the coding regions match the sequences of bacteria and eukaryotes. Those sequences that are similar to bacteria are genes related to energy production, cell division, and metabolism, whereas the transcription, translation, and replication gene sequences seem to be more similar to eukaryotes. EM/ Methanococcus jannaschii /EM consists of three p...

Amino Acids Dna Molecule
1,152 wordsIntroduction Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable the next generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each "side" is a chain of alternating phosphate and deoxyribose sugar molecules. The "steps" are formed by bonded pairs of purine-pyrimidine bases. DNA contains four such bases the purines a...

Test Tube Water Bath
622 wordsPurpose: To investigate the effect of temperature on the fermentation of glucose by bakers yeast. Hypothesis: If to separate tubes of 20 % glucose solution with 1 mil of yeast is added to battery jars filled with 20 and 38 c water then the warmer one will cause the yeast to ferment at a quicker rate. Materials: - 2 test tubes (100 mm. Long x 11 mm. I. D. ) - 2 ones-hole stoppers (size 00 w/ 3 mm. Hole) -Glucose -Bakers yeast suspension -Balance -Molding clay -Submersible test tube racks -Pins -M...

George W Bush And The Kyoto Agreement
541 wordsIn 1997, the worlds major political figures, Including President Clinton of the United States, signed the Kyoto Protocol to the United Nations Framework Convention on Climate Change. (1). While successful negotiation of the Protocol is a positive step for the global environment, it is only a small step. A number of obstacles such as some nations economic interests conflict with the Protocol, have to be overcome if the Protocol is to produce real reductions in emissions of greenhouse gases that h...

Hydrogen Bonds Hydrogen Ions
1,205 wordsProperties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earths precambrian seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted to itsel...

Carbon Dioxide Nitrogen Oxide
1,100 wordsThe greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. ? The glass? lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO 2), and methane which comes mainly f...

Degrees Celsius Test Tubes
1,993 wordsEffects of Temperature, pH, and Gelatin on Bromelain Introduction Bromelain is an organic catalyst that speeds up the rate of chemical reactions. Bromelain is used in this experiment to catalyze the break down of proteins and is called a proteolytic enzyme. Enzymes enable reactions to occur at a lower temperature and energy levels. This allows many reactions to occur inside living organisms that would otherwise have been impossible to take place. This enzyme is found in fruits, leaves, and stems...

Carbon Dioxide Nitrous Oxide
1,288 wordsThe Clouded Atmosphere Clouded Atmosphere The concentration of the atmospheres main greenhouse gases specifically, carbon dioxide, methane, nitrous oxide, and water vapor, have increased significantly during the industrial age. These high concentrations are predicted to continue in the atmosphere for thousands of years to come. This increase in specially carbon dioxide, increases the infrared energy taken in by the atmosphere, and warming the earths surface. The Global mean temperature over the ...

Green House Effect Effects Of Global Warming
1,263 wordsGlobal Warming is a great climatic phenomenon. The earth s temperature is rising and it is due to human activities. This rise in Earth s overall average temperature may seem minor or even irrelevant, but it is problem that should be taken seriously by the people and governments of this planet. Global warming is a serious threat to man s well being that he has brought upon himself. Global warming is caused by the Green House Effect. The Green House Effect is a natural part of the earth s atmosphe...

Burning Fossil Fuels Average Global Temperature
1,498 wordsGreenhouse Effect The greenhouse effect is a natural phenomenon that warms the earth and enables it to support life. Without it, the average temperature on earth would be around - 18 degrees C, instead of the current + 15 degrees C a frozen wilderness. It works on the same principles as the ordinary glass garden greenhouse, where glass allows light to get in, but does not allow for the heat to get out. This makes for a much higher temperature inside the greenhouse. On a planetary scale, similar ...

Polar Ice Caps Rise In Sea Level
2,227 wordsThe Greenhouse Effect Issue Statement While some people believe the earths climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earths surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes throu...

It is one of the more common inherited brain disorders. About 25, 000 Americans have it and another 60, 000 or so will carry the defective gene and will develop the disorder as they a...

Lower Low Water 20 Degrees C Californianus
1,189 wordsMytilus Californianus, Mytilus Californianus Introduction Mytilus Californianus, also known as the California mussel, is one of the most common creatures on California's rocky shores and in tide pools. They are generally grayish black in color and have very hard shells that only the strongest (or smartest) of predators can open. These mussels attach themselves to rocks very tightly. From time to time they sneak their foot out and touch the rocks, secreting a special thread of cement. After doing...

Washington D C Ozone Hole
1,498 wordsThe reappearance of the ozone hole over Antarctica has been a hot topic for scientist around the world. A few of these scientists are the atmospheric physicist Richard D. Mc Peters and several of his colleagues at the NASA Goddard Space Flight Center in Greenbelt. The ozone hole showed up earlier than expected, and it was wider and thinner. It appeared in mid-August, about two weeks ahead of schedule, and on September 19 reached the record size of 10. 5 million square miles, more than three and ...

Thermo Regulating Indoor Cabinets Plants
598 wordsIt is hard to believe that some plants produce as much heat for their weight as birds do, which are the greatest heat producers of all. It is even harder to believe that some are able to thermo regulate, which means that they actually alter their heat production to keep their temperature constant in fluctuating air temperatures. This is similar to what mammals do. The article I am reviewing tells about few a plants that do this, and how they do it. There are only three plants which have yet been...
