The Giant Anteater

... The funny thing is that the baby anteater is actually capable of a slow gallop four weeks after birth. How is that for spoiled? The giant anteater has a tube-shaped head and a long, slender snout. Giant anteaters certainly live up to their name; some grow to be over six feet in length, with a tail 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 tur ...

Fusion Energy

... power source on earth. Once we have started the reaction, Fusion requires no energy and realeases energy in a great surplus. It also has no environmental problems and causes no pollutions whatsoever. The problems with fusion are the molecules of hydrogen that are supposed to be fused, electro-statically repel each other at a great force. The only way to create the conditions where the it is possible to force these atoms together and override their repulsion is through enormous heat, this method is called thermonuclear. Even thoug ...

Environmental Crisis

... that they themselves have created. The claim that we have an environmental crisis because we have a people crisis is valid because our environmental problems have largely resulted from population growth, which has lead to apathy and inaction with regard to the wasteful consumption of resources. Examples are the desertification of the Sahel in Africa, the one child policy in China and the mis-management of our oceans. The Sahel is a strip of land that extends for more than 6000 kilometres across the southern edge of the Sahara des ...

Rubidium

... when heated, produced a distinct red line, this element they called rubidium from the Latin word meaning, "deepest red." * Where it is Found * Its Form * What it Looks Like * Physical Properties Rubidium is a fairly abundant element in the Earth's crust, there it is found in 310 parts per million (ppm). This makes it the 22nd most abundant element on Earth. It is found in many minerals, and brines, along with other elements. Seawater contains 0.2 ppm, twice the amount of Lithium found in the oceans. Traces are found in seawater ...

Endocrine Disruptors

... their effects. It has been suggested that these hormone changes can, in turn, lead to a variety of health problems including cancer, decreased fertility, and abnormalities in newborns. Evidence provided to support these claims of human and wildlife harm is largely from laboratory studies in which large 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 n ...

Atomic Theory

... (a chemist, who many consider the person who started the atomic theory) proved that atoms are always joined together basically the same way, and that the smallest part of a chemical compound was a molecule. He said that "All atoms of an element have the same chemical behavior, but different elements have atoms with different chemical properties." Scientists weigh gases by holding the same amount of a gas in a container and then wighing it. In the 20th century, most scientists used oxygen as the standard gas to compare other gases' weight ...

Cloning

... (HCF1998), is a scientific process in which a strand of DNA from one organism with the egg cell of another which creates a genetically matched life form. The actual merging process between the cells is called Nuclear Transfer. In this process the nucleus of one donor cell is removed and placed into a lab dish and starved of nutrients; it is then placed into a lab dish with a fertilized egg cell. Naturally, the cell that was starved will try to fuse with the healthy cell but it will need a little help. These two cells are then electrifi ...

Cfcs Cause Deterioration Of The Ozone Layer

... helium, and ozone. This atmosphere extends many miles out from the earth's surface. However, this layer is not a uniform layer, from top to bottom. As one moves out from the planet's surface the atmosphere becomes progressively dense. This atmosphere can be divide into four major regions. The first region is the troposphere which extends about 6.5 miles above the planet's surface. The troposphere contains the oxygen that we breath and is where a majority of our weather takes place. Beyond the troposphere is the second region of the atmos ...

Dna 4

... and proteins together make up chromatin which is foiled and coiled. DNA makes an exact copy of itself just before cell division begins. This process of DNA duplication is known as replication. The hydrogen bond between the base pairs of the 2 nucleotide strands weaken, and the 2 strands break apart. Each strand acts as a template forming a new nucleotide. This is accomplished by the acting of 2 sets of enzymes - DNA helicase enzymes and DNA polymerase enzymes. The DNA helicase enzymes separate the 2 nucleotide strands. The site where the hel ...

White Tigers

... challenges that have been thrown at them, these challenges that are decreasing their survival and slowly pushing their species to extincintion? are an endangered species and it is said that less than a dozen have been seen in India in about a hundred years. In fact no sightings have been reported since 1951. This may be caused that the Royal Bengal tiger population has dropped from 40,000 to 1, 800 in the past ten years, and as few as 1 in every 10,000 tigers is white (www.cranes.org/whitetigers.com). are neither albinos nor a special sp ...

Memory Debate For Psychology

... rather fragile. A human's long-term memory has a relatively permanent and limitless storehouse. Humans also have short-term memory, which is activated memory that only holds a few items briefly, things such as the seven digits of a phone number while dialing, before the information is either stored or forgotten, activated human activity memories rapidly decay unless used or rehearsed. Encoding can be an automatic process, this occurs when little or no effort, without awareness, and without interfering with our thinking about other things. E ...

Evolution Theory

... in a paper. Darwin’s theory is that as plants or animals spread to new areas, or as the conditions change different variations would be favoured in different places. This would mean these variations would spread through the populations of the plants or animals. Over time this would finally lead to a development of new species. This theory was explained in the book ‘The Origin of Species’, which describes his studies on the Galapagos Islands in the Pacific Ocean. He noticed that the species on the islands varied slightly ...
