... all times. Each day I provided the seed with the equal amount of water. In this experiment I had one control which was the plant in the dark. Results and conclusion: My hypothesis was correct. As you can see from the data graphs at first the seeds germinated at the same rate until the tip of the radicle broke trough and was visible. Afterwards the seed which was in the light grew more rapidly then the seed which was in the dark. I think this happened because when the seed is in the early stages of germination it does not use light to grow but is controlled by phytochrome. Which is a hormone that controls the germination of a seed before it reaches light. After the ...

... plastic, which is made from fossil fuels. Someone will either come up with a synthetic plastic or come up with something to substitute for plastic. The person who comes up with the solution will become and instant millionaire and everyone will be happy. There is one draw back of this way of solving problems, I mean sure it's great to wait until the demand but we should still learn from our mistakes. We should learn to plan ahead and see what the consequences could possibly be. We still have other demands to meet, there are three major demands of fossil fuels and they are heating, transportation, and industry. Although transportation is taken care of, we may not ...

... this gradation, some opponents to euthanasia believe that voluntary, passive euthanasia is the same as suicide; involuntary euthanasia is considered to be murder. Because euthanasia poses classic dilemmas as to its morality, it is not surprising that many issues arise in the legal and medical arenas. In law, the resolution of a particular case cannot always be applied to resolve another. In the medical realm, interpretation of medical doctrine concerning treatment of terminally-ill patients can result in entirely different applications. In two relatively recent cases, the Supreme Court had to decide the future of patients that were considered to be in chron ...

... of the overhead sun. These changes in the pressure systems over Asia generate the unique Asian monsoon circulation which prevails over China throughout the year. Surface Pressure Field and Winds: For any fluid to initiate movements, pressure gradient must exists. Therefore, for a close understanding of the circulation system that operates over China, we should start from discussing the seasonal pressure distribution at sea-level over the Asia-Pacific region, which is the driving force for the air movements in China. Most clearly to be seen, the largest difference in the atmospheric pressure occurs between winter and summer, whereby January and July can be consi ...

... A study shows roughly 80% of diseased individuals experience insomnia (depression.com 1). Possible problems may include: difficulty in falling asleep, waking up in the middle of the night with difficulty returning to sleep, waking up too early in the morning, brief periods of REM sleep, unusually long periods of stage 1 (light) sleep, or unusually brief periods of stage 3 and 4 ( deep, restorative) sleep (depression.com 1). Weight and depression are also commonly associated with each other. Many people begin loosing interest in eating which results in weight loss. Others may experience the opposite effect and gai ...

... The first night that they were in their new home, the Grandfather was so disorientated. Even after he was put to bed, he would repeatedly downstairs and ask Hank and Catherine where he was. The second day in town, the grandfather did something that no one could believe. He just awoke form his nap when he heard a noise that was very familiar to him. It was the sound of a train whistle. He ran running to the window and saw the smoke from a train headed toward town. A memory was triggered in his head and he went running from the house toward the train. While running to the train, he started to think back to when he used to work on the train. He was tried to re ...

... the ozone layer. Oxygen makes up approximately twenty percent of air and ozone makes up only 3 x 10-5 percent of air. Furthermore, this minuscule amount of ozone is enough to protect the earth from most ultraviolet light. Ozone prevents most UV-B radiation from reaching the surface of the earth (Environment Canada, 1996). Ozone is very important to life on earth because the harmfulness of high-energy UV-B radiation stems from the high energy of these light rays, enabling them to penetrate deeply into water, plant tissue and epidermal tissue of animals. Increased UV-B radiation results in harming the metabolic system of cells and ultimately damage to genetic mate ...

... heavy nucleus, allowing the process to repeat itself. This is the chain reaction that makes nuclear weapons possible. In a fusion nuclear device such as a hydrogen bomb, lightweight nuclei are forced to fuse at very high temperatures into heavier nuclei, releasing energy and a neutron. In order to squeeze the two nuclei together, an atomic fission bomb is usually used. A fusion reaction releases about four times more energy per unit mass than a fission reaction. The United States supervised the development of the atomic bomb under the code name Manhattan Project, during World War II. The first nuclear chain reaction occurred in December 1942, at the University o ...

... The Koppen Climate Classification system is comparatively simple and is based on a triad of letter symbols. The first (capital) letter is the critical one; the A climates are humid and tropical; the B climates are very dry; the C climates are humid and mild; the D climates reflect increasing cold; and the E climates mark the polar areas. The first letter is followed by two more letters that further define the climate of that region. The second letter represents and explains the dry season: whether there is or isn't a dry season, whether it is a short or long dry season, and what season it comes in either a dry winter or a dry summer. The third letter defi ...

... the acidic precipitation can have serious repercussions on both the environment and as well as human structures. On average, acid rain is about nine times more acidic than rain water, and has been recorded as low as 2.5 on the pH scale (forty times more acidic than water.) Acid deposition kill fish, soil bacteria, and as well as aquatic and terrestrial plants. the acid also drain the soil of essential nutrients such as aluminum and releases them into bodies of water such as streams, lakes, and ponds. These bodies of water develop highly concentrated levels of these nutrients which can really harm the aquatic life forms in that area Those areas without any alkaline m ...
