Autumn A Magnificent End
Words: 510 - Pages: 2.... from the mind because of the beauty in that event which the eye beholds-with humans it should be the same thing. People should not feel sad seeing their elder loved ones change their colors and whither but rather rejoice from the knowledge that they lived a magnificent life and their death is merely the start of a new beginning.
After all the leaves have fallen, and the ground is littered in seas of immense color, the very structure that carried the leaves remains-the trees. They live on long after the leaves have fallen and died and remind us that no matter how long, cold, and terrible the winter is a new spring will come. Even though .....

How To Build A Pond
Words: 314 - Pages: 2.... plants for the pond and its surroundings that make the pond look genuine. Plants at the water's edge are usually different from those found on the surroundings higher ground. Especially reminiscent of natural ponds are large plant's that leaves overhanging the water's edge, and plants with long thin, grassy foliage that grows in the shallows. These will all help to cover the water edge, which is almost never seen in a natural pond. Most nurseries sell aquatic plants. A pond that is meant to look natural requires much less maintenance than a formal pool, were clean, clear water is generally preferred. If the site has a low area, a pon .....

Hurricane Flloyd
Words: 1093 - Pages: 4.... continue along this track for 72 hours. Floyd was in an area very favorable for development and satellite images indicated the system was strengthening. The center of the system was not yet well defined, but forecasters believed Floyd could reach major hurricane strength with maximum sustained winds of 112 mph or more after 72 hours.
Tropical Storm Floyd Continues to Intensify
Washington, September 9, 1999 -- The National Hurricane Center (NHC) reported that Tropical Storm Floyd was located about 450 miles east of the Leeward Islands. The strong tropical storm and had maximum sustained winds of 60 mph. NHC Forec .....

Cloning
Words: 1210 - Pages: 5.... Humans have learned from nature and started
their cloning saga also. In one method of artificial cloning used in plant
breeding, cells are cut from a plant and placed in a flask with a nutrient
medium. The cells grow and divide, forming embryonic tissues that are
transferred to soil, where they produce complete plants. Grafting is
another method of cloning used in Horticulture. Matching cuts are made in
the stems of two plants, which are then fitted together so that their
transport systems are in contact. The wounded area heals, and the two stems
become a single physiological unit. All the McIntosh apple trees now in use
and many other f .....

Intermolecular Bonding Essay
Words: 1586 - Pages: 6.... ions to be formed
by elements is corespondent to the octet rule, when atoms react,, they tend to
do so in such a way that they attain an outer shell containing eight electrons.
The factors that effect the formation of ions are ionization energy, electron
affinity, lattice energy.
Figure 1
The transfer of electrons involved in the formation of (a) sodium chloride and
(b) calcium fluoride. Each atom forms an ion with an outer shell containing
eight electrons.
For many elements, compounds cannot be formed by the production of ions, since
the energy released in the formation of the lattice of ions would be
insufficient to overcome the ener .....

Nuclear Fusion
Words: 886 - Pages: 4.... person in an industrialized country. (Environmental Organizations, Source 4)
The problems with fusion have been numerous. One of the problems is attaining the correct temperature for fusion to take place without using more energy then you produce. Fusion reactions occur at a sufficient rate only at very high temperatures. Over 100 million degrees Celsius is needed for the Deuterium-Tritium reaction, while other reactions require even higher temperatures. (Hotta Labs, Source 1)
The density of fuel ions must be sufficiently large for fusion reactions to take place at the required rate. The fusion power generated is reduced if the fuel .....

Galileo And The Telescope

The second observation was the four moons of Jupiter. Galileo observed points of light that changed their positions with time around the Planet. These points he concluded were the four moons that orbit Jupiter. It showed that there were things in the heavens that Aristotle knew nothing about. The was not unique anymore because it wasn’t the only planet to have objects orbit it. .....

A Big Problem: Shortage Of Fish
Words: 976 - Pages: 4.... that the water be re-opened for fishing.
Problems for concern to many, are that all the regeneration that has occurred due to the closure of these waters will all be for nothing if re-opened because the same problem will happen again. Another concern is that the equipment that is used by the fishermen to catch the scallops not only do just that, but they also pick up everything else in their path. This has an impact on all marine life, particularly species such as sponges and barndoor skate which were almost forced to extinction because fishermen can't control what is being caught in the nets. The final concern is that reopening .....

Essay On Global Warming
Words: 776 - Pages: 3.... the emissions of greenhouse gases have been increasing due to the increase in technology that humans have developed (example, factories). These human-induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests.
These human practices have already changed the chemical make up of t .....

Life Sciences SIG: Gut Issues - Essay About Dietary Fibers
Words: 534 - Pages: 2.... the various types of dietary fibre are
the product of sunlight, water and carbon dioxide combining in green plants.
Most form part of plant cell walls. But unlike the other carbohydrates,
fibres do not break down into sugars in the human digestive system and then
course through the blood stream fueling muscles and nerves. Rather, when
eaten they tumble intact through the stomach and small intestine and end up
in the colon where billions of bacterial feed on them - in turn producing
intestinal gas. No wonder, then, that dietary fibre has been unwelcome in
many of history's nicer neighborhoods.
Even 20th century doctors reaso .....
