Effects Of Acid Rain On North Americas Aquatic Ecosystems
Effects Of Acid Rain On North America's Aquatic Ecosystems In the past century, one of the greatest threats to North America's aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems, as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain, and what can be done to improve North America's water quali

His discoveries have saved countless lives and created new wealth for the world. Among his discoveries are the pasteurization process and ways of preventing silkworm diseases, anthrax, chicken cholera, and rabies. *BR* Pasteur sought no profits from his discoveries, and he supported his family on his professor's salary or on a modest government

Why Cant Human Dive Us Deep Us Other Diving Animals?
Why Can't Human Dive Us Deep Us Other Diving Animals? When a diver dives deep for a period of time, breathing regular compressed air, a certain amount on nitrogen will be dissolved in the blood. If the diver comes back up to the reduced pressure of the surface too quickly, small bubbles of nitrogen will form in the blood stream. This is called the bends and requires the person to spend some time in a decompression chamber to gradually reduce the pressure and allow the nitrogen to escape the body

For decades people in societies worldwide have taken advantage of the Earth's waters simply by dumping whatever they do not want into them.

Industrial Revolution Prior to the 18th century, in the United States and Western Europe, the majority of the population lived on farms. However, during the 1700's many remarkable new innovations came into being which caused an upheaval of sorts. ?New forms of power, such as steam, replaced animal strength and human muscle. The factory system of making goods came into use. All of these advances affected patterns of living as well as working. Because society was so transformed, this time of great

We torture and heartlessly kill creatures that we arrogantly consider lesser beings simply at our disposal. For something as simple as eye makeup animals are tortured an

Female Genital Mutilation The practice of female genital mutilation, also known as female circumcision, occurs throughout the world, but it is most common in Africa. Female genital mutilation is a tradition and social custom to keep a young girl pure and a married woman faithful. In Africa it is practiced in the majority of the continent including Kenya, Nigeria, Mali, Upper Volta, Ivory Coast, Egypt, Mozambique and Sudan. It is a cross-cultural and cross-religious ritual, which is performed by

For years, part of the American public, and humans in general, have been fascinated with the possibility of creating human life by other than natural means. There are many who strongly disagree with the idea of human cloning. It certainly wasn't surprising when they were able to clone a sheep and will not be the least surprised if someday scientist's will be able to clone a human being.

Oh we would say that perhaps at some point in the distant future, cloning might become feasible through the use of sophisticated biotechnologies far beyond those available to us now.

The term birth control, coined by Margaret SANGER in 1914, usually refers specifically to methods of contraception, including STERILIZATION. The terms family planning and planned parenthood have a broader application. METHODS OF BIRTH CONTROL Attempts to control fertility have been going on for thousands of years. References to preventing conception are found in the writings of priests, philosophers, an

One year later, Myron Essex and his colleagues (1) found that AIDS patients had antibodies to the Human T-cell Leukemia virus Type-1 (HTLV-I), a virus discovered by Gallo a few years earlier. At the same time, Gallo and his colleagues (2) reported the isolation of HTLV-I from AIDS patients and advocated a ro

Cheetahs can and should be saved because they have a difficult time surviving on there own due to poor parenting skills, cub mortality, and energy demands.

They are mollusks of the Class Cephalopod, along with the nautilus, cuttlefish, and octopus. Squids are highly evolved, and have developed a number of traits uncommon to most other mollusks. Fossil records of cephalopods have dated back the Cambrian Period (about 600 million years ago). Structurally, squids have only small variations of a basic theme common to all cephalopods.

We compared monotremes, marsupials, and placental mammals at both warm and cold temperatures. The results supported our hypothesis that when temperature increased, metabolic rate decreased.

For the most part, however, the ethical concerns being raised are exaggerated and mis

Contrary to what most people think, even though Blue whales live in the sea, they are mammals. They breathe air, have their babies born alive and can live anywhere from 30 to 70 years. The Blue whale is a baleen whale, and instead of having teeth, Blue whales have around 300-400 baleen plates in their mouths. They fall under the category of the rorquals, which are the largest
