Time To Change
Words: 747 - Pages: 3.... from harmful UV rays. Finally,
we have a major impact on the degeneration of natural resources. Millions of
gallons of oil, coal, and other valuable resources are wasted each day. These
are just a few of the human disruptions to nature available to our knowledge.
We are conscious of many more, and there are probably others that we are not
aware of. If we do not start taking them seriously soon it will be too late,
if it is not already. We need to reevaluate our priorities and plan for the
future existence of this world.
A group labeled the Earth-Firsters' often attempt to accomplish this task
through drastic and sometimes dangerous .....

Sedimentary Rocks
Words: 693 - Pages: 3.... chemical sediment, and most chemical also contain some loose sediment material.
All are in general characterized by the parallel arrangement of their mineral layers or beds, which are distinguished from each other by differences in thickness, the size of the grains, or color.
All rock disintegrate slowly as a result of mechanical weathering and chemical weathering. Mechanical weathering is the breakdown of rock into particles without producing changes in the chemical composition of the minerals in the rock. Ice is the most important agent of mechanical weathering. Water percolates into cracks and fissures within the rock, freezes, and .....

The Giant Anteater
Words: 346 - Pages: 2.... of about three feet (Encarta ‘98)!
Anteaters' tongues are two feet long, and the animals can move them in and
out of their mouths up to 150 times per minute (Schupska 1). The giant
anteaters lives on the ground. It walks with its front feet turned on the
sides to protect its claws, which the animal uses to rip open ant nest
before eating. Then it flits its long tongue and literally licks up the
ants. The anteater precedes to rip oben a termite or ant hill with its
clawed hand and work its tubular snout down into the heart of the colony,
trapping the insects on its tongue's sticky coating (Encarta ‘98). The
anteater also uses the cl .....

Weather Forecasting
Words: 968 - Pages: 4.... 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 have made private forecasts for small areas.
Meteorologists are people who interpret the weather, the reason I don't
say predict the weather is because even though all forecasters have the same
information and data at their fingertips, the way that they interpret what is in
front of them can be different. Meteorologists receive information from various
sources, but their interpretation of the da .....

Avalanches
Words: 990 - Pages: 4.... aren’t very dangerous, I will discuss slab . The fundamentals of how these snow masses occur, what to look for when testing and just all-together prevention.
The basic chemistry behind a slab avalanche is when one layer of snow does not bond to the layer below it. Any kind of temperature change, fresh snowfall, the weight of a person, all can cause the slab to break free from the lower layer. The formation of a slab is possible in many ways. One way is for the snow to develop a crust and then there be more snowfall. Since snow doesn’t bond to the crust it becomes a potential for an avalanche zone. Another way is for surface hoar to deve .....

Biotechnology

predict what kind of medical misfits there will be in the future,
using this life-saving technology to their own personal, perhaps evil,
advantages.
Dealing with politics, Bioengineering has opened a whole new
door pertaining to the military, whose use of it may create an
ultimate destruction. The alterance of nature is un-natural, and creates
an unbalancement in life. When we use this technology towards the
wrong side, we may all be burned. You see, Biotechnology has the
ability to altar what diseases we humans are susceptible to, and when
scientists create something to eliminate immunities to disease .....

stimulate the formation of new brain cells in people with
Alzheimer's or other diseases where brain cells degenerate, he
commented.
Goldman noted that the use of drugs to stimulate proliferation of
new brain cells will probably result in a more successful strategy
than attempting to grow the cells outside the body and then
placing them back into the brains of patients, as some scientists
have suggested.
Goldman, of Cornell University Medical College in New York,
and colleagues surgically extracted brain cells from the
hippocampus of eight living male patients, ranging in age from 5 to
63 years, while they u .....

Predator - Prey Relationships

can be located in or on the host animal or animal of the other
population(Boughey 1973). No known organism escapes being a victim of
parasitism(Brum 1989).
Parasitism is similar to preditation in the sense that the parasite derives
nourishment from the host on which it feeds and the predator derives nourishment
from the prey on which it feeds(Nitecki 1983). Parasitism is different from
most normal predator prey situations because many different parasites can feed
off of just one host but very few predators can feed on the same prey(1973). In
parasite-host relationsh .....

Alcohol 2
Words: 390 - Pages: 2.... drinking the fermented juices of certain fruits, berries, and grain produced an extremely pleasant effect. Among primitive peoples, alcoholic drinks increased the excitement of tribal festivals. In more civilized nations, beers and wines in the daily diet were believed beneficial to health.
During the 1800’s, a movement began in the United States to prohibit the manufacture and sale of alcoholic beverages. A constitutional amendment banning the beverages went into effect in 1920, but thousands of Americans defied the prohibition law. In 1930, the federal government estimated that about 800 million gallons of alcoholic beverages were being .....
