The Dog Domestic dog, carnivorous mammal, generally considered the first domesticated animal. The domesticated dog has coexisted with human beings as a working partner and household pet in all eras and cultures since the days of the cave dwellers. It is generally believed that the direct ancestor of the domestic dog is the wolf, originally found throughout Europe, Asia, and North America. Remains of a dog, estimated to be 10,500 years old, have been found in Idaho. TAXONOMY Kingdom: Animalia Phy
The Downy Woodpecker Habitat Downies take home in the United States and southern Canada. They have been recorded at elevations of up to 9,000 feet. The downies are not deep-forested birds, preferring deciduous trees. Open woodlands, river groves, orchards, swamps, farmland, and suburban backyards are all favorite haunts of the downy. Downies will also nest in city parks. About the only place you won\'t find them is deserts. The most attractive human dwelling sites are woodlands broken up by logg
The Ebola Virus INTRODUCTION The most deadly killers on this earth are too small to see with the naked eye. These microscopic predators are viruses. In my report, I will answer many basic questions concerning one of the fastest killing viruses, the Ebola virus. Questions such as "How does it infect its victims?", "How are Ebola victims treated?", "How are Ebola outbreaks controlled?" and many others related to this deadly virus. GENERAL INFORMATION The Ebola virus is a member of the negative str
The Genetics of Violence Introduction We, in the 1990ís, are slowly and inevitably being faced with the sociological and biological implications of impending genetic power. This power is analytical, in such cases as the Human Genome Project, which will hopefully succeed in mapping out the genetic code for the entire human genetic composition. Moreover, this power is preventative and participatory in that it can be, and is being, used to control the behavior of humans and other animals. This new
The Koala Inroduction The koala is the Australian jewel. It has very furry, ash colored hair, a rubbery black nose, sharp claws, fuzzy ears, and a grizzly personality, or should I say, koalality. If you kill a koala, you\'ll make a million off their fur! They would sell the fur to coat companies and make coats out of koala fur. Well, sadly enough, too many people are making millions on koalas. That\'s why they\'re endangered species. Habitat The koala is distributed along the eastern coastal sem

Introduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that ar
Darwinism: The Theory That Shook The World Other than Mendellson and his studies with genetics, Darwin has by far contributed the most to our modern science. From his theories on variation of species to his explanation of natural selection Charles Darwin has shocked the world by proving the world older than previously thought and creatures not immutable. In this present day these theories are as common belief as a simple mathematical equation such as two plus two equals four; but in the year eig
The Tiger The Tiger is often described as a particularly dangerous, sly, and invincible predator. The Tiger is the largest of the cat family. They have powerful bodies, large paws, and very sharp claws. The head of the Tiger is rounded and has a convex profile. The ears are black with white in the middle. The Tiger\'s eyes are a yellowish-orange color, but at night they almost look green. Coloration of the Tiger is reddish yellow or rust- brown on the upper side, and a whitish under side. There
Turkey Vultures Vultures are large birds of prey closely related to hawks and eagles. They are divided into New World vultures and Old World vultures, both belonging to the order Falconiformes. The New World vultures, in the family Cathartidae, consist of seven species in five genera. Among the New World vultures include the Cathartes aura, also known as the Turkey Vulture. Scientists say that turkey vultures are shy, inoffensive birds. Some researchers have discovered that the bird is very help
Twinning in Cattle Mac Winslow Dr. Farin ANS 220 3 December 1996 Due to the continual fluctuation of the cattle market cattle producers have been searching for ways to improve their production and increase their profits any way possible. For years genetic engineers have been working hard on improving economic efficiency in cattle. It is their hope that through genetic research they can improve the yield and the income of cattle producers around the world. Research has shown that twinning is one

Four problems faced by animals on land ar
The Touch of Magic by Lorena Hickok The book I chose to read is called The Touch of Magic written by Lorena A. Hickok. The story was about Anne Sullivan Macy, Helen Keller\'s wonderful teacher. I had never heard of Anne before I read this book, but while looking in the library my mom explained to me who she was and she seemed like she would be an interesting person to do it on. I was right. Anne Sullivan Macy was born on April 14, 1866 in Feeding Hills, Massachusetts. At the age of nine she was
Ebola Virus With a ninety percent mortality rate, high mutation capability, and opportunities for genetic re-assortment Ebola Zaire is one of the most deadly and unforgiving viruses in the known world. A new family of viruses termed filoviruses, was first discovered in 1967 Marburg W. Germany. Ebola Zaire was first isolated in 1976 at Center of Disease Control, Porton Down in the UK, and at the Institute for Tropical Diseases in Antwerp, Belgium. Immunological uniqueness was found in the laborat
Hypotheses of the Effects of Wolf Predation John Feldersnatch December 1st, 1995 Abstract: This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates. The four proposed hypotheses examined are the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. There is much research literature that discusses how these hypotheses can be used to interpret various data s
Extinct Animals Research: Woolly Mammoth We have learned much about the Woolly Mammoth almost more than any other dinosaur that has been identified. Due to the fact that the Woolly Mammoth so closely resembles today\'s elephants, care for them would most probably require most of the same factors to keep it alive. Since the Woolly Mammoth has been extinct for 4000 years, it is difficult to tell exactly what they lived on, but we can hypothesize. The Woolly Mammoth lived during the Ice Age, so if
Analytical Chemistry Analytical Chemistry is the branch of chemistry principally concerned with determining the chemical composition of materials, which may be solids, liquids, gases, pure elements, compounds, or complex mixtures. In addition, chemical analysis can characterize materials but determining their molecular structures and measuring such physical properties as pH, color, and solubility. Wet analysis involves the studying of substances that have been submerged in a solution and microan
Cancer: The Costs, Causes, and Cures Cancer is a major killer of people all around the globe. We do not have a definite cure, but the amount of research done on this one disease costs on the average of $1.2 billion dollars annually, and $20 billion annually in care of cancer patients. What is Cancer? Cancer is a broad ranging term that is used by many people, including medical professionals such as doctors. Cancer, in its most fatal and aggressive form, is of a larger class of diseases known as
Cloning Richard Pech 6-5-96 per. 7 Cloning, is it the thing of the future? Or is it a start of a new generation? To some, cloning could give back a life. A life of fun, happiness, and freedom. For others it could mean destruction, evil, or power. Throughout this paper, you the reader, should get a better concept of cloning, it\'s ethics, the pro\'s and con\'s, and the concerns it has brought up. You will hear the good of what cloning can do and the bad that comes with the good. Most of the infor
Copper Blake Adams Period 3 Grade 8 2/5/97 Copper is a mineral. it is not a plant or a animal. Copper is a metallic metal. It can never be broken down into differnet substances by normal chemical means. Copper was one of the first metals known to humans. People liked it because in itís native condition, it could easily be beaten into weapons or tools. Copper has been one of the most useful metals for over 5000 years. Copper was probably used around 8000 B.C by people living along the Tigris and
Ethical Procedures and Guidelines Defining Psychological Research Psychological research is often a very controversial subject among experts. Many people feel that there are many moral standards that are often not followed. Others may believe that there is much harmful misinformation that can often be harmful to subject and others. Still others believe that psychology is a lot of theories without any reinforcing information. Whether any of these assumptions may be true or not, there have been gu
Geothermal Energy Matt Arnold 9/17/96 Physics 009 Professor Arns The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons. Hydroelectric power tends to upset the ecosystems in rivers and lakes. It affects the fish and
Iron Iron in its pure state is soft, malleable and ductile (that can be stretched, drawn or hammered thin without breaking ((Webster\'s Dictionary, 419, 1988)) with a hardness of 4-5. It is easily magnetized at room temperatures and this property disappears when heated above 790 degrees Celsius.. Metal iron occurs in a free state in only a few localities, notably Greenland (Encarta, 1996). One of the physical properties of iron as an ore is its color which can be black, brown or even reddish.

Alfred Binet, born in Nice, France, on the eleventh of July, whose mother was an artist and whose father was a physician, became one of the most prominent psychologists in French history. Having received his formal education in both Nice and later, in Paris, at the renowned Lycee Louis -le-Grand, Bin
Phosphates Phosphates may be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valuable as a detergent

Burrhus, was a stenographer and a secretary, in a law office and later in a railroad chief executive\'s office. His father, William A. Skinner, was an attorney, who studied law with another local attorney at a New York Law School. Skinner\'s parents were both good students. His father had bought several sets of books, so there was a lot of reading material their children. Skinner
Carl Jung Carl Gustav Jung (1875-1961) was a son of a minister in Switzerland. He was born on July 26, in the small village of Kesswil on Lake Constance. He was named after his grandfather, a professor of medicine at the University of Basel. He was the oldest child and only surviving son of a Swiss Reform pastor. Two brothers died in infancy before Jung was born. Jung\'s mother was a neurotic and often fought with his father. Father was usually lonely and very irritable. When the child could not
Charles Darwin Charles Robert Darwin was a British scientist who laid the foundation of modern evolutionary theory with his views on life development through natural selection. He was born in Shrewsbury, Shropshire, England, on February 12, 1809. After graduating from the elite school at Shrewsbury in 1825, Darwin attended the University of Edinburgh where he studied medicine. In 1827 he dropped out and entered the University of Cambridge in preparation for becoming a clergyman of the Church of
Acid rain Acid rain is a great problem in our world. It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on it\'s own is not the biggest problem. It cause many other problems such as aluminum poisoning. Acid Rain is deadly. WHAT IS ACID RAIN? Acid rain is all the rain, snow, mist etc that falls from t
Acid rain is pollution Acid rain is a common term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce a rain, snow, or hail of sulfuric and nitric acids. Such pollution may also be suspended in a fog, or the pollutants may be deposited in dry form. Environmental damage from acid rain has been reported in northern Europe and North America. High levels of acid rain have also been detected in other areas of the world, such as above the tropical rain f
Acquired immune deficiency syndrome Acquired immune deficiency syndrome, or AIDS, is a recently recognized disease. It is caused by infection with the human immunodeficiency virus (HIV), which attacks selected cells in the IMMUNE SYSTEM and produces defects in function. These defects may not be apparent for years. They lead, however, to a severe suppression of the immune system\'s ability to resist harmful organisms. This leaves the body open to invasion by various infections, which are therefor
Acupuncture As An Alternative Medicine In The Western Culture Debora Cytrynowicz Acupuncture as an Alternative Medicine ( in the Western Culture) Alternative medicine is a very general term whose definition can be very controversial.

AIDS. Is the message getting through? AIDS - What\'s new ? ------------------- Is the message getting through? We already know enough about AIDS to prevent its spread, but ignorance, complacency, fear and bigotry continue to stop many from taking adequate precautions. We know enough about how the infection is transmitted to protect ourselves from it without resorting to such extremes as mandatory testing, enforced quarantine or total celibacy. But too few people are heeding the AIDS message. Per
An End To Genetic Diseases The United States has a very diverse heritage. There is no American race. Americans are the blending of many cultures throughout many generations. With this blending of cultures comes a blending of genes. In the past, genes have not been well understood. They were not understood until Mendel did experiments on plants to find out why different plants of the same species had different characteristics. His goal was to find the key to unlock the mystery of inheritance (Cop
Application of Magnets For Levitation In ancient times men knew of a special kind of rock that could pull other rocks of the same kind and pieces of iron toward themselves. Such rocks were called lodestones. Today man uses the same force exerted by electromagnets and permanent magnets to provide magnetic aide to trains and more efficient power generators. This report will focus on the use of magnets in the generation of electricity and magnetically aided trains. Magnetism is defined as the force
Asthma Asthma is a disorder that affects 20% of Australians in their childhood. It causes airways to narrow making it difficult to breathe. Symptoms may include loss of breathe in cold weather, wheezing and whistling. It may occur periodically in sudden sharp attacks. When an attack occurs - The muscles around the wind pipe tighten shrinking the airways. The wind pipe lining then swells (picture) and a mucus called phlegm develops causing the cough to intensify and slightly more painful. What ar

Bears Beware In our world today many animals and plants are loosing their fight against human intervention in their once well-balanced ecosystem. We are all aware of the extinction of the dinosaurs and the dodo birds, however most people do not realize that annually thousands of species of our flora and fauna are now becoming extinct. This on going trend is increasingly threatening our bio diversity and global ecology. To give a specific example of animal depletion I will focus on Canadian bears
The Bengal Tiger The Bengal tiger is a carnivorous, mammal primarily from India. It lives in habitats such as the coniferous Himalayan Forest, the mangroves of the Sunderbans, the hills of the Indian Peninsula, or the forests of Rajasthan and Northern India. At one time Bengal tigers were scattered throughout Asia. Now they are generally found in India and some regions of Bangledesh, Bhutan, Nepal, and Myanmar. There is approximately 4,000 alive in the wild now, and about 300 are in captivity in
Biology Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on.

Birth Control The practice of birth control prevents conception, thus limiting reproduction. 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, and
Birth Defects Birth defects, or congenital malformations, are the faulty formation of structures or body parts present at birth. Sporadic, hereditary, or acquired defects may be immediately observed or may become manifest later in life; they may be visible on the body surface or present internally. Birth defects may be life threatening and require surgical correction, or they may interfere with function or appearance. It is estimated that about 3% of all children are born with major defects; min
Boa Snakes Boa is the common name for about 6 genera and 50 species of SNAKES that constitute the family Boidae. Closely related to PYTHONS, the family includes the largest of all snakes, the water-dwelling ANACONDA of South America. Among other boas are the smaller sand boas, Eryx, and the woodsnakes, Tropidolphus and related genera. The typical boa genera are ground or tree dwellers of tropical America--as are the woodsnakes--and the island of Madagascar, whereas the sand boas are semidesert b
Cats As Carnivorous Predators Cats as Carnivorous Predators Throughout the course of evolution the catís ability to survive in the wild has become extremely dependent upon its hunting ability. In order for feral, or undomesticated, cats to survive on their own in the wild they have developed hereditary traits and instincts from their ancestors throughout time. Though these hereditary traits that they have inherited are helpful for undomesticated cats, they can often cause problems when domestica
