Pesticides Are Affecting Our F
Number of words: 2666 - Number of pages: 10.... reproductive harm, neurological and development toxicity, immunotoxicity, and disruption of the endocrine system.” Children are more likely to be affected by pesticides than adults because, they are strange eaters, they breath at a higher rate, and tend to spend more time on the ground were chemicals may settle and then enter a child’s body through breathing, orally, by touching something with a residue and then putting their fingers in their mouth, and through a child’s skin. Pesticides will drastically damage the future health of our children if people don’ .....

The Age Of The Earth
Number of words: 582 - Number of pages: 3.... be a good alternative. If a pound of the metal Uranium is left to decay, it would take approximately 4.5 billion years for it to turn into half a pound of Lead ( Howter, 1996, Radiometric Dating: An Exercise in Faith). As it turns out, this is what scientists believe to be.
The assumption that the earth is 4.5 billion years old has raised doubts in the minds of some skeptics who question the accuracy of the data used in radiometric dating! They claim that without knowing the exact amount of Uranium in the beginning, most of the calculations will be based on ass .....

Twinning In Cattle
Number of words: 2067 - Number of pages: 8.... that the producer be well
educated on how to handle twinning, in order for it to be successful for them.
Many agencies see twinning as an economic move upward. The American
Breeder Service has made efforts to produce semen as well as embryos with high
predicted breeding values available to producers. They have been recorded based
on twinning probabilities and ovulation rates. A large amount of work on
twinning has also been done by the Meat and Animal Research Center. Since the
early eighties, they have located cattle with a high frequency of twinning and
b .....

Acid Rain 12
Number of words: 1314 - Number of pages: 5.... In the same period, Norway's emissions were reduced by more than 70 per cent.
· As a result of higher precipitation in recent years, sulphur deposition has not dropped as much as might be expected from the reductions in emissions.
· Estimates of how much pollution the environment can absorb without damage are called critical loads.
· Sulphur, like nitrogen, is essential to all animals and plants. The natural sulphur cycle includes volcanic emissions, sulphate in sea salts, and sulphur compounds produced by marine organisms. On a global basis, emissions f .....

Hurricanes A-level
Number of words: 882 - Number of pages: 4.... heat and it is the latent heat that initiates the development of the storm and consequently produces heavy rainfall.
When the hurricane reaches its maturity an eye develops in the centre, in the eye there is a relative area of subsiding pressure. Which is what causes clear skies, anomalous high temperatures and light winds. Eventually the eye disappears as a result of the descending air increasing instability, which in turn warms and increases the storms intensity. Around the eye there are towering Cumulo-nimbus clouds. The hurricanes decline as soon as the sour .....

The Ocean
Number of words: 1232 - Number of pages: 5.... are (1) wind-driven circulation and (2) Thermohaline circulation.
Wind-driven circulation result from the wind sets the surface waters into motion
as currents. The currents generally flow horizontally-that is parallel to the
earthˇ¦s surface. The wind mainly affects only the upper 100 to 200 meters of
water. However, the flow of wind-driven currents may extend to depths of 1,000
meters or more.
Thermohaline circulation produces great vertical currents' hat flow from the
surface to the ocean bottom and back. The currents largely result from
differences in water t .....

Are UFOs Real?
Number of words: 3163 - Number of pages: 12.... theory, however, that UFOs come from outer space is called the extraterrestrial hypothesis. The only problem with this theory is the distance involved in interstellar travel. Another hypothesis on the nature of UFOs is the demonic force hypothesis. It states that the UFOs represent demons coming to earth for the final battle between good and evil (Randle 112). The not so widely accepted theory is that of hallucination/dream. Its major debunker is that mass hallucinations would have to be fairly common. The final hypothesis on UFO sightings is the null hypothesis .....

From Legend To Science The Health Benefits Of Tea
Number of words: 1781 - Number of pages: 7.... water. After drinking some tea, he discovered its miraculous powers and immediately placed tea on his list of medicinal herbs.
John Blofeld, in Chinese Art of Tea, writes that ˇ§it can be confidently stated that tea was known in the three kingdoms epoch (AD 222-277).ˇ¨ More importantly, however, ˇ§tea [was] originally drunk for its medicinal properties.ˇ¨ (Blofeld 4) Evans links the early popularity of tea to Taoist religious practices during the Qin Dynasty (201 ˇV 207 B.C.). ˇ§Taoists in particular became obsessed by long life and an Elixir of Life became .....
