Have a throbbing headache? An ache behind the reddened eyes. Relentless now, two days ago you were normal. Nausea now sets in with a spiked fever. Next you began to vomit. After a while of intense vomiting you end up with dry heaves, and at the same time you start to become strangely passive. Your face starts to loose its normal appearance, the glow is completely gone. Your face is now an expressionless mask with slightly droopy eyelids. Your eyeballs are fixed and paralytic and you can'

The effect of stretching on the muscles of athletes A bit about our muscles… Our muscles are made up of very small filaments that are called Myrofribrils. Some of these are thicker than others. A bridging, locking. mechanism, which prevents these filaments from disengaging when they get to a certain length, permits motion of each muscle within a certain range. When we stretch regularly we can achieve an improvement in the resting length of a muscle. If we don't stretch regu

Tara Feeney Oct. 24, 1997 1st Period Cardiovascular System The cardiovascular system, also known as the circulatory system, refers to the course taken by the blood through the arteries, capillaries, and veins and back to the heart. This system enables dissolved materials - oxygen, carbon dioxide, nutrients, and wastes - to be transported throughout the body. Without the cardiovascular system the cells of the body would not be connected to the organs that

Dermatology Dermatology is a medical specialty dealing with the diagnosis and treatment of diseases of the skin. These are conditions of the skin such as rashes,acne,warts,moles,skin cancers, etc. Dermatology developed as a subspecialty of internal medicine in the 18th century; it was initially combined with the diagnosis and treatment of venereal diseases because syphilis was an important possible diagnosis in any skin rash. It's scientific basis however was not established until

The asteroid, more commonly known as the starfish, or sea star, is an invertebrate that lives mainly in an ocianic environment. These unique and unusual creatures have a number of arms that protrude away from their spiny skinned bodies. The exact number of arms depends on the species; some have only three, and the most is 42. Most people commonly associate the starfish with haveing five arems. However, there are many species of starfish that have 3, 4, 6, 7, and 8 arms. Each arm that extend

Lymphomas are cancers of the lymph nodes and lymphatic tissues which make up the lymphatic system. The lymphatic system produces lymphocytes, cells that help the body fight diseases. One type of lymphoma is Hodgkin's disease, which along with at least 10 other types of lymphoma cause around 50,000 lymphoma cases globally every year. This accounts for about 5% of the world's cancer cases. The exact cause of lymphoma is still unknown, but some speculate that lymphomas could be hereditary, or

The Plague is a word that horrified much of the population over the centuries around the globe. It is no less fearful a word today. This term describes several diseases; the three most common forms are known as the Bubonic Plague, Septicemia, and Pneumonic. Plague pneumonia, or pneumonic plague, is caused by the same bacteria as bubonic plague but is acquired by inhaling infected droplets from the lungs of someone whose plague infection has spread to the respiratory system. This is the most cont

Bottlenose Dolphins The Bottlenose Dolphins Live in Fiordland New Zealand. It is a spectacular environment where it snows all winter and sometimes part of the fiord freezes over. The sides of the fiord are like big pillars of rock reaching way out into the sky. The fiord also consists of great number of wild life including Flora, Fauna, Seals, Penguins, Crayfish, and some types of Sharks. Bottlenose Dolphins live in-groups called pods usually the pod increases in size with water depth

The effects of pH on mung beans Gloria Cheng Winsy Cheung Lily Wong Christine Yen January 15, 1998 Abstract This experiment explores how different pH environments affect the growth of mung beans. The mung beans were grown in water with various pH levels, consisted of pH levels 5, 6, 7, 8, and 9. A replicated design was used consisting of 3 runs for each pH level. The following results are listed in order of pH levels allowing most growth to least growth of the mung beans: 7, 8, 6

Marfan's Syndrome is most often a hereditary disease. The gene which causes Marfan's Syndrome is a dominant gene, yet, Marfan's Syndrome is a very rare disease. It is estimated that 5 out of every 100,000 people have Marfan's Syndrome. If one parent has Marfan's Syndrome, there is a 50% his/her children will have it as well. In some cases, Marfan's Syndrome is not always hereditary. Nearly 15% of the people who have it did not get it from a family member. In these people, it occurs because

Essay of Eukaryotic Organelles 10/1/96 The mitochondria has an eggshape structure. The mitochondria consists of an inner and outer membrane. The outer membrane is what shapes the organelle to its egglike shape. The inner membrane which folds inward makes a set of "shelves" or cristae that allow the reactions of the mitochondria to take place. The more the mitochondria makes these reactions the more the inner membrane folds. This happens because the mitochondria now has more surface area

TRISOMY 18 SYNDROME DEFINITION: A chromosomal disorder resulting in a syndrome characterized by specific (small) dysmorphic features and organ malformations. EPIDEMIOLOGY: incidence: 1/8000 live births most die in embryonic or fetal life 2nd most common autosomal aberration 2nd most common multiple malformation syndrome age of onset: newborn risk factors: advanced maternal age F > M (4:1) HISTORY: 1960 first recognized as a specific clinical entity by the discove

Leukemia is a disease characterized by the formation of abnormal numbers of white blood cells, for which no certain cure has been found. Leukemia is also conditions characterized by the transformation of normal blood-forming cells into abnormal white blood cells whose unrestrained growth overwhelms and replaces normal bone marrow and blood cells. Leukemias are named according to the normal cell from which they originate, such as Lymphocyte Leukemia. Lymphocyte Leukemia is where a Lymph

The Coelacanth is a large fish that is closely related to today's lungfish. These two fishes are the lobe-finned fishes left on the earth. They're called lobe-finned fishes because of a muscular lobe they have at the base of each fin. The Coelacanth is believed to have been around since about 350 million years ago. The amazing thing about the Coelacanth is that modern ones are almost identical in every way to ancient ones found fossilized in sedimentary rock. Another amazing thing about this fis

The Dodo bird is one of the most famous recently extinct animals. Its story is also another sad tale of human interference. The Dodo bird was a mystery to many of the people who lived in the same time period as it. Its existence was sometimes even considered a myth. Nevertheless, historians and scientists have been able to piece together sketchy accounts of the history, anatomy, and life of the Dodo using information found in documents written by travelers, fossils found in the Dodo's former hab

Genital Herpes Virus In this world today there are many viruses that effects the human population. Herpes is one of these diseases. It is no less then a self-limited communicable disease. Yet its "victims" describe it as devastating, and society treats those with it like lepers. Until recently most people had never heard of herpes virus. Even doctors were familiar with the virus, yet in the past few years , it has become an epidemic. Why I chose to study

To do genetic research on a fruit fly one must understand the life cycle of the fruit fly. Also, to do the research, one must know how to: prepare a vial, subculture, isolate virgins, and make crosses with mutant flies. In addition to doing all of the above, one must know how to identify the differences between male and female fruit flies. Finally, a scientist must know how to keep accurate records of all research. The complete metamorphosis involves four steps. The first step is the egg

Seth Garnar What would you do if you had the power to make an exact clone of yourself? The topic of human cloning has become a center of focus lately. Some people want to ban it while others don't. My view on the topic is that there should be a temporary ban on it until we know more about it. In this paper I will briefly explain how human cloning is accomplished and explain my reason for a temporary ban. Embryo splitting or blastomere separation is what is most commonly referred to as

DNA is a very large polymer made up of many monomers called nucleotides Each Dna nucleotide consist of: a. the sugar deoxyribose b. a nitrogen base The only difference between the four types of Dna is there nitrogen bases. The four nitrogen bases of DNA are the organic ring structures a. adenine b. thymine c. guanine d. cytosine One way to determine the structure of a substance is by X-ray diffraction. X-ray diffraction----a beam is passed through a pure crystal of the substanc

A hundred and fifty years ago in September, 1845, the Dublin local paper "Dublin Evening Post", reported a "disease in the potato crop". This turned out to be the potato blight which destroyed 40% of the crop that year and almost 100% the next year. The devatation was known as "The Great Hunger" and resulted in wide spread starvation and mass emigration to Britain and the Americas. As a result, the population declined from @8,295,000 to less then 6,000,000 in a few years. In 1845 a fungal

A Strained Back In this report I plan to tell you what a strained back is, how to take care of it, how to prevent it, and how to tell a strain and a sprain apart. I hope that this report is informative enough for you to be able to handle a strained back if it where to occur. A strain is an injury to a muscle and tendon system. Overexertion causes the fibers that connect muscle to tendons to stretch and sometimes even tear. A "pulled muscle" is actually a strain. When you strain y

Transgenic Technology: "Cloning" Techniques Transgenic Technology Transgenic technology can introduce a gene or genes from one individual's DNA into the DNA of another individual- even when the genes come from different species. The gene or genes are inserted in to a fertilized egg and become integrated in to the DNA of that zygote. Nuclear Transfer Technology It is possible to replace a complete set of genes (called a genome) using nuclear transfer technology. The nucleus, which contains

The Shoulder The shoulder is a versatile and very necessary joint for normal human activity, but if injured proper recovery must be applied to restore movement and strength. The shoulder is a very interesting and useful joint. The structure of the bones and positioning of muscles allows for a wide range of movement and makes it powerful. T

Throughout all of the polar regions of the entire northern hemisphere roams the largest carnivorous quadruped alive in the world today, Ursus maritimus. More commonly known as the polar, this huge mammal is ruler of its domain by being well adapted to its environment. The physical characteristics of polar bears make them a perfect fit in the arctic. They have a heavy stout body with strong muscular legs and well-adapted neck muscles. Their eyes are small and deep set to protect them against

What is a theory? What are some different theories of evolution? These questions and many more will be answered in this paper. This paper includes some amazing facts. People once believed that maggots (a fly-like insect) came from rotten meat, not from their parents like all animals do. Charles Darwin and Alfred Wallace came up similar theories on Natural Selection (a theory that is explained later in this paper) at around the same time, but Darwin?s theory is more commonly heard of. Also,

In this assesment the student will identify the chareracteristics and roles of carbohydrates, proteins, lipids, and nucleic acids in a living system. Write a 4 paragraph report describing the atoms in the compound building blocks, types, structure, and function of each. The student must also describe what they would do if they were given a jar with an unknown substance to find out wether or not it contained any of the substances listed above. Proteins: Proteins are long chains of amino acids

Perhaps no single instrument has advanced man's understanding of the surrounding world more than the microscope. Scientific discoveries made through microscopic techniques are too numerous to list. The microscope revolutionized the study of biology, medicine, and many other fields of scientific research. Basic Principles Light microscopes use convex (converging) lenses. The way a lens magnifies an object depends on where its placement relative to the focal point of the lens. If the obj

Entomology is the study of insects, involving their biology and control in relation to their environment and to man. Entomology also had an independent scientific discipline which had roots in biology. Some entomologists are involved in reducing harmful species of insects that destroy food, housing, plants, and clothing and cause discomfort and disease to humans, livestock and household pets. Others develop ways to increase growth rate and spread the insects that provide food, polli

John James Audubon John James Audubon was born in 1785 Santo Domingo, which is now Haiti. After arriving in America in 1803, he began the extensive ornithological observations. Ornithology is the branch of zoology that deals with the study of birds. These studies would later lead to the publication of his bird drawings and paintings. His published collection, The Birds of America, was a collection of these works. It is considered a classic work of ornithological and American art. Th

Biology/Sociology One in a Million DNA fingerprinting (the use of a person s DNA to identify them) has become a hot topic in the field of law enforcement as well as the entire world. The controversy exists on whether or not it should be admitted in court as evidence at this time. Some experts believe that the present technology allows DNA fingerprinting to be used in cases for positive identification (proof that the DNA match was at the scene of the crime) because of the extreme unlikeness t

The Bogus Logic of The Beak People who have served in the Armed Forces may be familiar with the expression, "If you can't dazzle then with your brilliance, baffle them with your baloney." The Beak of the Finch uses such laughable logic, it is remarkable that anyone would believe it. The book does such a terrible job of presenting a case for evolution and history, that the only logical conclusion is that the book's true intent is to disprove it. Jonathan Weiner, The Beak of the Finch: A Story

Darwin and the Victrian era The Victorian Age was a time when many views on human existence and destiny were formed and discussed. Strictly speaking the Victorian era denotes the reign of Queen Victoria from 1837-1901. When this era came to an end, the ongoing concepts and controversies did not vanish. The old and the new are always confusingly interlocked in culture. The twentieth century inherited some of the ideas of the nineteenth century. Some of these new ideas culminated elaborate phil

Nature of the Work Biological Scientists Nature of the Work Biological scientists study living organisms and their relationship to their environment. Most specialize in some area such as ornithology (the study of birds) or microbiology (the study of microscopic organisms). About two-fifths of all biological scientists work in research and development. Some conduct basic research to increase knowledge of living organisms. Others, in applied research, use knowledge provided by basic rese

Charles Robert Darwin is considered by many to be the father of modern biology. He introduced the theory of evolution and natural selection to a time in which science was based of the words on the Bible. He revolutionized the way life science was studied. Charles Darwin was born on February 12, 1809 in Shrewsbury, England. He was the fifth child of Dr. Robert Waring Darwin and Susannah Wedgwood Darwin. As a young child, he developed an interest in hunting and collecting rocks and insects. At

Charles Darwin and Richard Owen Wars occur everyday, whether it be pushing and shoving or shooting and bombing. During the 1800's, a different war of conflict took place. This so-called war between Charles Darwin and Richard Owen circled on the topic of evolution. As much as it would liked to have this essay based upon a physical war between these two opposing figures, it is not the case. This war involved the use of text written by Darwin and meanwhile having Owen misinterpreting it

One of man s greatest attributes is the ability to imagine. No other creature could make mental images of how reality might be, nor invision a part of the future. We make theories based on how things could have been or might be in order to quench our thirst for curiosity. One of these theories is the theory of evolution. This theory, according to many, answers the question, Where do we come from? . This essay will determine that the theories of evolution (past and present) are incorrect

From his theories that he claimed were developed during his voyage, Darwin eventually wrote his Origin of Species and Descent of Man, which exploded into the world market over twenty years after his return home. Wallace, King and Sanders wrote in Biosphere, The Realm of Life: "In 1859, Charles Darwin published a theory of evolution that implied that humans evolved from apes. . .The Darwinian revolution was the greatest paradigm shift in the history of biology, and it greatly changed t

The common name is the African Elephant, the scientific name is Loxodonta Africana, the phylum is Vertebrata, the class is Mammalia, the order is Proboscidea, and the family is Elephantidae. The Closest Relatives to the African Elephant are: the Asian Elephant, mammoths, primitive proboscidean (mastodons), sea cows, and hyraxes. Scientists believe that the African Elephant evolved from one of its closest relatives, the Sea Cow. The geographical location and range of the African

Lynx by Cody White Academic Orientation Mr. Keown period 7 December 19, 1997 With a pounce and a hop the speedy lynx chases the bleached white hare through the bushes. Poof! The hare disappears into the shiny white powder. Then the sly lynx picks up the scent of the hare and pounces toward the small hairball. The sharp elongated claws donÕt dig in, and the hareÕs long slender legs launch himself out of the hole and out of danger. The swift cat swings his claws around to hit

The Blue Whale The blue whale or balaenoperta musclus is the largest animal to ever have lived on Earth. Whalers have reported this whale to being over 100 feet long and weighing over 150 tons! The blue whale is a mammal, because it has milk, hair, and the embryo develops in the mothers womb. The blue whale is a type of baleen whale. The blue whale eats mostly plankton and crustaceans like krill or copecods. The blue whale is located in the Atlantic Ocean. The smaller species of th

Our land our bodies and our cows are all effected by the meet industry. Our land and water is getting polluted from animal waste. Our bodies are getting sick from germs in meat, and the cows are being tortured and are suffering. Waste from livestock in the United States amounts to130 times the waste produced by people. In Central California 1,600 dairies produced more waste than a city of 21 million people that’s 5 tons for every person on this earth, and their is not

BUTTERFLIES: Butterflies are flying insects, which comprise the order Lepidoptera with. There are about 15,000 to 20,000 kinds of butterflies. Butterflies are holometobore insects. The largest butterfly ever found is the Queen Alexandra’s butterfly. Scientific and non-scientific vocabulary words which must be learned before reading this section in alphabetical order: Abdomen: (noun) 1. The part of the body in mammals, that lies between the thorax and the pelvis. 2. In arthropods

Abstract The Blue whale is the largest creature of the sea, in fact, it is the largest creature known to man. 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 o

In Africa there are many types of animals, one of them is the Colobus Monkey. There are different types of Colobus Monkeys: there is the white Colobus, the red Colobus, and the olive Colobus. The Colobus Monkey is a long tailed tree living primate. The Colobus Monkey can be found all over Africa. The Monkey’s hair color varies from were the live. The Colobus Monkey is very unique. It comes in many types of color, is very active in social behavior and is very smart as shown in their
