From the Paper "Science can be broadly defined as the development of knowledge about the physical world. The history of science is the explanation of the development of this knowledge. Science is often viewed as cumulative and progressive by its nature. Such views, however, can have profound implications because not all scientists or theorists follow the cumulative view. Scientists use both deductive and inductive reasoning to hypothesize the possibility of a useful theory. They also seem to be able to decide or discover more easily which theories are false rather than which theories are true. While the proving or disproving of scientific theory plays a vital part in the growth of science and scientific inquiry, the way that the actual progress or creation and discovery of new ideas and paradigms of thought is at the center of scientific research. Does science move forward in a cumulative and progressive manner or does it move forward in leaps and bounds? "
From the Paper "Phenylketonuria (PKU) is a genetic disorder characterized by an inability of the body to utilize one of the constituents of a normal diet- phenylalanine (PHE), which is one of the essential amino acids. Essential amino acids cannot be synthesized within the body. It means that they have to be taken in from the foods. PHE is found in all protein foods such as meat, eggs, fish, milk, cheese, and so forth. "
Abstract This paper is on the Wetlands and the effects civilization is having on them. The author contends that there exists a need for action, through the use of education, and federal/ locally sponsored programs. He fears that without major steps, and an increase in federal protection, we may reach a point at which we are too late, and serious damage to the Wetlands will be done.
From the Paper "Wetlands" is the collective term for marshes, swamps, bogs, and similar areas found in generally flat vegetated areas, in depressions in the landscape, and between dry land and water along the edges of streams, rivers, lakes, and coastlines. Because they are so varied, wetlands can be difficult to recognize. Many have been altered by human activities such as farming, ranching, and the building of roads, dams, and towns. Yet their importance is critical is the proper functioning and balance of our many ecosystems."
Abstract This paper discusses the environment and its relationship with technological progress. The author uses figures, numbers and statistics to demonstrate the environmental paradox, the faulty thought that things are worse than they were before, when in fact they are getting better. The author also looks briefly at future advances in technology such as cloning and genetic engineering and argues for the far-reaching advantages it will provide the human race and environmental science.
From the Paper "In this paper I set out to prove the environmental paradox. The world is getting better and better every day, we live in the greatest time the human race has ever had ? and people say it's going to the dogs. I would like to end this paper with a quote from P.J. O?Rourke: ?Things are better now than things have been since men began keeping track of things. Things are better than they were only a few years ago. Things are better, in fact, than they were at 9:30 this morning, thanks to Tylenol and two Bloody Marys.? (O?Rourke, p. 2) "
Abstract This paper presents the causes and effects of air pollution. Other stratospheric research is concerned with the downward trends in global ozone that have recently been measured over populated regions in the mid altitudes. The author focuses on the various factors associated with global warming.
From the Paper "Air pollution is any visible or invisible substance found in the air that is not part of the normal composition of air. Some air pollution is natural and has always been a part of the earth's history. However, over the past one hundred years or so, pollution created by humans has become a major environmental problem. Natural air pollution has been around for millions of year. Dust and a variety of gases from forest fires, volcanoes, and decaying material in rivers, oceans, and other bodies of water continually enter the atmosphere. Sometimes this natural pollution can have dramatic effects. Air pollution is a major factor in causing humans to get ill. Tuberculosis, bronchitis, heart and chest diseases, stomach disorders, asthma and cancers can all be traced to chemicals in the air. Pesticides and fertilizers release gases and particles into the air which poison people and kill animals."

Abstract This paper provides a look at human cloning, and examines the discrimination dimension of the cloning process. The author discusses the pros and cons of cloning, religious opposition, and societal worries. The paper also discusses the problem of overpopulation, financial costs of cloning, and potential discrimination of clones from humans.
From the Paper "Genetics is of increasing importance in the world of the 21st century. New developments in this field are finding more and more applications in every day life. Concerns about this science, due to its inherent conflicts with religious doctrine and traditional norms and unfamiliarity to the public have been frequently presented in the media. Recently, the public perception of genetics has appeared around such as human cloning. While many aspects of this subject are poorly understood, it isn?t in doubt that there raise many questions of great complexity."
Abstract The following defines and discusses the different types and causes of breast cancer. In addition it looks at how this cancer is treated, the different stages of this illness and the proposed treatment.
From the paper:
?A doctor should be seen if changes in the breasts are noticed. The doctor may suggest a mammogram. A mammogram is a special x-ray of the breast that may find tumors that are too small to feel. If a lump in the breast is found, the doctor may need to cut out a small piece of the lump and look at it under the microscope to see if there are any cancer cells. This procedure is called a biopsy. If the biopsy shows that there is cancer, it is important that certain tests (called estrogen and progesterone receptor tests) be done on the cancer cells. Estrogen and progesterone receptor tests may tell whether hormones affect the way the cancer grows.?

Abstract This essay examines the role of genetics in schizophrenia making reference to several monozygotic and dizygotic twin case studies as well as adoption studies. The influence of pre-natal environment on schizophrenia and brain imaging as confirming a physiological basis for schizophrenia are also dealt with in this essay.
From the paper:
?When looking at possible genetic causes for a disorder as complex as schizophrenia, the researchers must control as many variables as possible. They cannot control the possible influences of neonatal events, child rearing or other life events that might contribute to the person's mental state.?
This essay takes the reader step by strep through the dissection of a fetal pig, outlining the organs and body systems they belong to, as well as giving a visual perspective on each organ.
Abstract This paper examines the anatomy of a fetal pig, and indicates how to gain dexterity with the instruments used in the dissection procedure. The author compares the anatomy of the fetal pig with that of the human body.
From the Paper "The first step was to obtain the Fetal Pig and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher's twine and secured the front and hinds legs using a lasso technique. To make the first incision I had to locate the Xifoid Process of the Fetal Pig, distal aspect of the sternum."
This paper highlights the advances in imaging technology that have allowed scientists to discover how memory works and the areas of the brain involved.
Abstract This paper looks at how the different advances in brain imaging-techniques have contributed to scientists increased ability to understand the concept of memory. It looks at the advent of Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET), and what they have meant to the increased ability to understand and treat brain, and memory disorders.
From the Paper "For example, fMRI was found useful for research by Awh and colleagues (1999) to observe brain activations during the performance of a spatial working memory task. In this investigation, subjects were given a spatial working memory task and a control task. Using fMRI the researchers found a functionally distinct, region that showed sustained activity during the spatial working memory task, confirming the location for the neural bases for that function. In the past, researchers who wanted detailed studies of human brain activity struggled because they lacked effective investigative tools. In experiments with humans the best technologies brought only limited success in mapping the processes of consciousness."
Abstract This paper examines the affects of global warming by utilizing extensive data to support the argument that global warming is a serious issue. This paper argues that he current global warming trend can be halted, but it will take the collaborative efforts of everyone to gradually phase out fossil fuels and replace them with alternative energy sources.
From the Paper "Imagine that you own a piece of beachfront property on the beautiful coast of North Carolina. The house has been in your family for years and you plan on passing it down to your children. In fifty years the ocean will have slowly crept more than halfway up the beach. Every high tide, waves pummel the pilings that support the entire weight of the house. Hurricanes have also become much more frequent and far more powerful. You begin to worry that if this continues, eventually the house will succumb to the forces of nature and crash into the sea. The following year, a devastating class Five hurricane wipes out every home on the beach. All that remains of your once beautiful vacation home is a concrete ..."
Abstract This is a detailed descriptive, persuasive paper about the effects of cloning including many of the ethical issues. It is more of a pro cloning paper then a con. The author discusses how cloning is accomplished and clearly defines many difficult biological terms, and the opposition's viewpoint.
From the Paper "Can you imagine a world full of people with the same genetic makeup? That would be the scenario if the technology to clone humans fell in to the wrong hands. Many people, when they think of cloning, think of a mass production of one particular race and morality concerns. This simply is not true. Cloning can be a useful tool in helping people with disabilities or life threatening illnesses. Cloning should continue to take place in today's society only if its results would be used to benefit the human race. In today's society, many people are concerned with the ethics of some of the advances in biological technology. Bio-technology had advanced so much, that ethics are a major concern to scientists and the people that fund their research. They have to make sure that they are not "playing God" and that their research has some significance to it, but many people wonder if cloning research is really necessary. They think that scientists are performing these cloning experiments just because they have the technology to do so and that they have no significance to them what so ever. This is a common misconception that the average person has. Cloning is being researched today in order to find alternative treatments to diseases that affect certain organs or tissue. Many more people will be willing to accept the concept of cloning and its role in the benefit of the human race if they knew just a little more about the subject."
Abstract A thorough discussion of the history and pros and cons of cloning in general. This paper supports cloning humans to help humanity so long as the ability is not abused. Topics presented include natural clones and philosophical, physical, medical and various other issues.
From the Paper "The word "cloning" once brought to mind a vast array of ideas and thoughts often possible only within the context of science fiction, and yet our technology has now reached a stage in which possibility has become reality. In 1996, the first successful mammalian clone was created and named Dolly - a sheep born asexually who had the exact same genetic sequence as her mother (Hawker). Recently, in 2001 a human embryo was cloned and grew to the 6 cell stage before it died (Hill). These two events have raised an enormous amount of questions surrounding the ethics and benefits of cloning. Even though cloning exists in nature (Identical Twins, bacteria, most unicellular organisms, plants not from seeds, some algae and fungi, many Invertebrates are all natural clones), there is a sense of taking evolution and nature into our own hands by cloning?most especially in context to cloning human beings (Hawker). There are strong arguments both for and against cloning, but I believe cloning is only feasible to help humanity so long as it is not abused."
Abstract An examination of which environmental factors may influence the development of one's personality or whether these traits are a product of one's upbringing. The paper looks at various factors and concludes that both nature and nurture are jointly responsible for the outcome.
From the Paper "It has been a long controversy about how nature and nurture imply to personality traits and human behavior. Nature means that genetic factor and the system of organs control the personality, while nurture means the personality is a result of conditioned circumstances where a person is brought up. It includes the personality of other people, like family, includes the teaching, and lessons a child gains during his/her mental development process."
Abstract This paper discusses how climate governs the entire ecological structure of the planet earth. The author examines how climate, in relation to the topography and latitudinal location, determines the vegetative types, the hydrology, soil, agriculture and various human activities.
From the Paper ?Climate represents a long term average of various weather features such as temperature and precipitation. The World Meteorological Organization uses 30-year averages to define climatological "normals" for these various features. Climate determines how resources such as water and vegetation are distributed and, until the onset of technology, climate also determined where people lived and worked. Many factors, such as topography, proximity to large bodies of water, and latitude affect a particular location's long-term climate. It is important to note that because a region's climatology is a 30-year average, significant year to year variability is likely. For example, a particular location may have a dry, warm winter one year and a record snowfall the next year.?
