The Effects Of Antibiotics On Bacterial Growth

... hot springs and areas of volcanic activity. They contain lipids but lack certain chemicals in their cell wall. Eubacteria are all other bacteria. Most of them are phototrophic, i.e. they use the sun’s energy as food through the process of photosynthesis. Another classification of bacteria is according to their need of oxygen to live. Those who do require oxygen to live are considered aerobes. The bacteria who don’t use oxygen to live are known as anaerobes. The shape of specific bacteria provides for the next step in the identif ...

Hurricanes 2

... Scientist do not know how this happens. But when it does, it's the first step in the birth of a hurricane. With the lid off, the warm, moist air rises higher and higher. Heat energy, released as the water vapor in the air condenses. As it condenses it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that t ...

Lenz's Law And Faraday's Law Of Induction

... the original change in flux. This is known a Lenz's law. Let us apply it to the case of relative motion between a magnet and a coil. The changing flux induces an emf, which produces a current in the coil; and this induced current produces its own magnet field. If the distance between the coil and the magnet decreases; so the magnetic field, and therefore the flux, through the coil increases. The magnetic field of the magnet points upward. To oppose this upward increase, the field produced by the induced current must point downward. Thus L ...

Role Of Government Intervention In Environmental Issues

... intervention, but should be as minimal as possible. I have chosen to examine the article from the New York Times entitled RU.S. Seeking Options of Pollution RulesS. Although pollution is detrimental to our environment, you have to take into account that it is almost impossible to entirely prevent pollution. This is scientifically impossible and it would have severely negative economic impact on the industries. So the core issue becomes the fact no matter what, there will always be pollution, as long as these industries exist. ...

Acid Rain 2

... in water. The resulting acidic water droplets can be carried long distances by very strong winds, returning to Earth as acid rain, snow, or fog. Who is affected? Basically every one who comes in contact with acid rain is affected. Among one of the serious side effects of acid pollution on humans is respiratory problems. The SO2 and NO2 emmisions give rise to respitory problems such as asthma, dry coughs, headaches, eye, nose and throat irritations. An indirect effect of acid rain on humans is that the toxic metals dissolved in the water ...

Eagles 2

... measure 3 feet from head to tail, weigh 7 to 10 pounds, and have a wingspan of about 6 1/2 feet. Females are larger, some reaching 14 pounds and having a wingspan of up to 8 feet. This striking raptor has large, pale eyes; a powerful yellow beak; and great, black talons. The distinctive white head and tail feathers appear only after the bird is 4 to 5 years old. Bald eagles are believed to live 30 years or longer in the wild, and even longer in captivity. They mate for life and build huge nests in the tops of large trees near rivers, lak ...

Possibility Of Terraforming One Of Earth's Neighboring Planets

... planetary environment. Terraforming by definition, is the application of technology for the purpose of influencing the global properties of a planet. The sphere of influence should incorporate the alteration of the planet's environment to the extent that it will facilitate human existence on that planet. In order to accomplish this, technology must be aimed at three specific, vital areas: The creation of an aquatic medium, a terrestrial plateau and celestial ether that is conducive to human respiration. There are two planets from which to cho ...

Alzheimer’s Disease

... and memory. The cells were bunched up like a rope tied in knots. He termed the strange nerve bundles neurofibrillary tangles. He also noted an unexpected accumulation of cellular debris around the affected nerves, which he termed senile plaques. In a medical journal article published in 1905, Alzheimer speculated that the nerve tangles and plaques were responsible for the women’s dementia. is a disorder marked by a gradual decline in brain function that gets worse with time. It used to be assumed that this change was a normal part of ...

Encephalitis -

... or other diseases. The specific viruses involved may vary. Exposure can also occur through insect bites, food or drink, or skin contact. Once the virus has entered the blood stream, it can localize the brain causing inflammation of brain cells and surrounding measures. White blood cells invade the brain tissue as they try to fight off the infection. The brain tissue swells (cerebral edema) and can cause destruction of nerve cells, bleeding with in the brain (intracerebral hemorrhage), and brain damage. This can cause neurologic defici ...

Weather Forecasting

... that in 1863 in Britain there was a united forecasting system headed by Captain Robert Fitzroy. Captain Fitzroy would send ships around Britain to warn people of storms and such. However, he was often wrong and criticized and therefor committed suicide. Since then there have been many other services, but the largest one currently is the National Weather Service. The National Weather Service gives predictions for all of the world through satellite imagery for all countries. Also in recent history many local television and radio stations hav ...
