You see the blood spattered room and pools of black vomit, expelled during the epileptic convulsions that accompany the last stages of death. Their hearts have bled into themselves, heart muscles softened and hemorrhaging , the brain clogged with dead blood cells (sludging of the brain), the liver bulging and yellow with deep cracks and the spleen a single hard blood clot. Babies with bloody noses born with red eyes lay dead from spontaneous abortions of affected .....

Theory Of Evolution
Words: 1237 - Pages: 5.... a "primordial soup" gradually formed which contained amino acids. These in turn got hooked together to form simple proteins, the "building blocks" of life. At some point these proteins happened to get connected in just the right way, and a threshold was crossed: the proteins started reproducing themselves, and simple life was "born".
During uncounted eons, this simple life gradually became more and more complex as chance modifications of the original proteins combined with external conditions of moisture, temperature, food supply, etc., to eventually produce all the varied and complex life forms inhabiting first the oceans, then th .....

Endocrine Disruptors
Words: 1702 - Pages: 7.... doses are fed to test animals, usually rats or mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associated with the presence of certain pollutants. Findings from such studies i .....

Devastation Of The Rain Forests
Words: 1653 - Pages: 7.... will mean the destruction of mankind.
The devastation of the rainforest may be compared to playing a game
of Russian Roulette. One-forth of existing medicines comes from tropical
plants whose homes are in the rainforests of South America. For every acre
that is lost in the burning season, there is one acre less that we have for
possible life saving medicines. About 70 percent of plants used in anti-
cancer drug come are the rain forest. We are slowly destroying the
environment and ourselves. Whether we realize it or not, the world could
quickly come to an ecological stop. Every day 144,000 acres of the
rainforests are cut .....

Aedies Aegypti
Words: 933 - Pages: 4.... and varied.
The Aedes aegypti, with regard to both sexes, are generally similar in coloration
(Womack 1993). The female adult is noticed by it’s small dark figure that is colored by
white markings and banded legs. Its proboscis or snout is mostly black with regard to
the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in
the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales
present on the insect (Womack 1993,
Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled for
about three-quarters, and dark scaled for about two-thirds (R .....

The Effects Of Acid Rain On Lakes And Trees
Words: 594 - Pages: 3.... subsequently it dies. Around the 1970s the acid rain dilemma got worse, the acid rain has put
trees in danger and now they are starting to die off. The effects of acid rain on a tree is shown if
it has less foliage, yellow spots and produces many cones (Baines, 22). Secondly, acid rain
damages the trees through the soil by releasing metals that harm them even further (Lucas, 72).
Acid rain makes the trees lose their leaves, so when the trees try to regrow their leaves, buds
come instead, this process is called a panic shoot (M. 15). Large land areas which used to be
covered with forests are now gone, dead or dyi .....

Nuclear / Particle Physics Effects Of The Atomic Bombs On Hiroshima And Nagasaki
Words: 2095 - Pages: 8.... isotope Pu-239 (Outlaw Labs). Fission occurs when a neutron, a subatomic particle with no electrical charge, strikes the nucleus of one of these isotopes and causes it to split apart. When the nucleus is split, a large amount of energy is produced, and more free neutrons are also released. These neutrons then in turn strike other atoms, which causes more energy to be released. If this process is repeated, a self-sustaining chain reaction will occur, and it is this chain reaction that causes the atomic bomb to have its destructive power (World Book, 1990). This chain reaction can be attained in two different ways.
The first type of atomic .....

Environmentalism
Words: 746 - Pages: 3.... one problem we are undoubtedly creating another one. One writer uses the analogy of a “mixing bowl” to describe the earth. This “mixing bowl” that is our earth is constantly being manipulated to create the perfectly balanced “mixture” (Huber). Since there will never be a perfect balance or “mixture”, what is the point of even trying? Maybe they are right in saying that we will never find the perfect mixture, but this negative attitude is part of the problem. Nothing will be accomplished unless we reject apathy and negativity.
One writer, T.H. Watkins, has criticized the idea of putting a “price tag” on the earth .....

Goundwater
Words: 2024 - Pages: 8.... to assess since it is not directly visible. Therefor with out complicated measurements, it is hard to say how much water there is left in your well. It is also difficult to tell where exactly the source of recharge for your well is. Thus if an area near your well becomes polluted, the pollution may seep into the groundwater feeding your well.
The purpose of this project is to explore the subject of groundwater, its place in the water cycle, how it seeps through the ground and how it accumulates in underground pockets called aquifers. The project will also examine the many uses of groundwater in agriculture as well as environmental prob .....

magnitude or brighter. Alpha Auriga (Capella) is the sixth
brightness star, at a visual magnitude of 0.08. The star is
43.5 light years away, and is about ten times the size of
our Sun. Capella's visual magnitude is really the combined
brightness of the primary star and another star that
revolves every 104 days. This star is also known as
Menkalina. The star name derives from the Arabic name Al
Mankib dhi'l Inan, "The Shoulder of the One Who Holds the
Reins," that is, "The Shoulder of the Charioteer." Several
open clusters are found in Auriga. Each contains about 100
stars and is about 2,700 light years away. The main p .....
