Abstract
This paper explains that the combination of deep-seated emotions, cutting-edge technology and huge amounts of money has made the supposedly intimate act of creating a child into a serious multi-national industry. The author of the paper points out that the growth of "the baby business" raises serious ethical concerns and then relates arguments for and against the practice of compensation. The author also points out that the obvious fear is that women will be exploited for their reproductive potential. The paper urges the creation of more federal regulations to adjust the various competing interests that weigh on this procedure.
From the Paper
"Critics charge that the payment of large sums of money amount of "commodification" of egg donation. This amounts to a label more than a sound objection. The market puts a price on virtually everything, and merely adding a financial element does not necessarily make something unethical. Perhaps the greatest need in this field is not control over payments but regulations to ensure that anyone agreeing to undergo the procedure is fully informed of the nature, risks, and potential complication involved, and that reproductive clinics accept responsibility if complications develop."

Abstract
This paper explains that the main organ responsible for gas exchange, the lungs, are efficient not only in their anatomic and histological structure but also are physiologically efficient to provide oxygen to tissues and cells such that oxygen extraction can be increased in altered, demanding physiologic states within the bounds of physical laws. The author points out that the oxygen cascade, essentially described as the "diminishing returns" phenomenon, represents a natural barrier to the limits of mammalian and human cellular respiration. The paper concludes that, from uptake of oxygen, to transport of oxygen to the periphery to its delivery to tissues at the cellular level, at the different steps, oxygen tension decreases pathologies at the tissue level, which are heavily dependent on perfusion and are the most vulnerable to hypoxia.
Table of Contents:
Lung Anatomy and Physiology
Oxygen Cascade
Uptake in the Lungs
Carrying Capacity of Blood
Global Delivery from Lungs to Tissue
Regional Distribution of Oxygen Delivery
Diffusion from Capillary to Cell
Cellular Use of Oxygen
Lung Pathophysiology
Oxygen Cascade Pathophysiology and Relevant Disease States
Uptake in the Lungs
Carrying Capacity of Blood
Global Delivery from Lungs to Tissue
Conclusion
From the Paper
"Delivery of oxygen to the tissues is heavily dependent on the heart and the vascular system associated with it. This branching, closed-circuit system perfuses all organ systems. In normal individuals, global delivery of oxygen (Do2) is often more than adequate to ensure that all tissues receive enough oxygen to meet their aerobic respiratory needs (Vo2). Do2 is the product of cardiac output (Qt) and oxygen content of blood (Cao2). Cao2 is similarly the product of oxygen saturation (Sao2), hemoglobin content (Hgb), and a constant K (the coefficient for hemoglobin-oxygen binding capacity)."

Abstract
This essay discusses recent discoveries in evolutionary studies, including the human genome project, and will speculate on the impact that these new discoveries will have on evolutionary studies. The paper concludes that we can look forward to substantial and possibly profound breakthroughs in terms of understanding what it is to be human, but warns that we should not expect to find the meaning of life with our microscopes.
From the Paper
"For example, since the completion of the human genome project, scientists have achieved another milestone: they have completed the genetic map blueprint of the chimpanzee. Due to the chimpanzee's close relationship to humans (in evolutionary terms), we now have the opportunity to better understand the evolutionary processes that have combined to create human beings. The scientific analysis has revealed that some 96% of human and chimp genomes are exactly the same. More important still are the insights provided by the differences between human and chimp genomes."

Abstract
The paper discusses the function of bones and identifies the five types of bones and their seven levels of bone structure. The paper looks at three types of bone cells and summarizes the most common medical conditions that affect bones.
Outline:
Introduction
Function
Bone Types
Hierarchical Organization of Structures
Bone Cells
Medical Conditions
From the Paper
"Bones also have a degree of toughness and elasticity that are required by their function. An examination of a bone structure will reveal that it is made up of two types of tissue. The first type of tissue is located on the external side and it is dense in texture and it is called compact tissue. The second type located internally is made up of thin fibres and lamellae, which are joined to form a lattice like reticular structure called cancellous tissue."

Abstract
The paper discusses the two most common types of twins; identical and non-identical twins, also known as monozygotic and dizygotic twins. The paper looks at the differences between identical and non-identical twins. The paper then talks about a third type of twins; half-identical or polar body twins.
Outline:
What Are Twins
Types of Twins
Identical Twins
Comparing Non-Identical Twins with Identical Twins
A Third Type of Twinning
From the Paper
"In a normal pregnancy, a single baby develops in the uterus of the mother. In very special circumstances, two and sometimes even more babies develop simultaneously in the mother's uterus. This is called a multiple pregnancy. Twins are two babies in a multiple pregnancy. Twins are considered very special and present a fascination for science and society. In the fields of psychology and sociology, there is a special subfield called "twin studies". Twins studies are especially important in the search for answers to the nature vs. nurture question. What is the most important factor in human development: genetics (nature) or environment (nurture)?"

Human Cloning, 2008.
An analysis of the current issues that involve both religion and medical science in relation to developments in human cloning.

Abstract
This paper analyzes the medical issue of human cloning, noting that it is pertinent to ethics, since it involves a great deal of scientific questions as to how science is "playing God." The religious perspective is analyzed through Roman Catholic arguments against human cloning to better understand how this conflict is developing between both factions. In essence, this paper analyzes the two sides of the "playing God" issue in relation to the medical scientific advancements of human cloning.
From the Paper
"The Catholic point of view on procreation is an act that occurs from the union of two people, those married under God's union and vows. Cloning is direct violation of the act of two people, and socially makes for an unethical third party (scientists) to be involved in this sacred union between two people. This perspective often brings forth the changing element of a society that is steadily becoming less dependent on religious doctrines, which invariably must give way to the empiricism of modern science. In essence, Catholic Bishops oppose cloning of new human lives because mankind does not have the right to play God."

From the Paper
"Cultivation of chives is relatively easy because the plants are hardy and can grow in a broad range of environmental conditions. They can grow in different kinds of soil, from sandy, to loamy to heavy clay. However, the soil should be moist but well-drained. Chives can grow in a broad range of soil pH from acidic soil, to neutral or and even in highly alkaline soil. They thrive in areas with semi-shade or direct sunlight."
"Bulbs or seeds should be planted in early spring and bulbs should be planted deeply. Bulbs grow in clumps and have to be divided 3 to 4 times a year. Because they are perennial plants and resistant to frost, they can be planted outside and the leaves can be harvested the whole year round."

Abstract
This paper discusses the risk factors and causes of throat cancer, as well as the treatments for the cancer and the resulting voice impairments. The paper futher discusses how speech rehabilitation and assistive devices impact on the emotional and psychological status of a patient. In light of this, the paper then offers recommendations for speech rehabilitation.
From the Paper
"Cancer of the throat can be caused by a virus or by lifestyle habits such as a long history of smoking or excessive alcohol intake. When a virus is involved, the prevalence is much higher for women whose cancer develops because of an infection with papillomavirus (HPV), which is the same virus that causes cancer of the cervix (American Cancer Society, 2007). When throat cancer is not caused by smoking and alcohol, the prognosis is good with radiation therapy. The likelihood of the cancer returning and leading to death is reduced for patients whose cancer originates with a virus (American Cancer Society, 2007)."

Cloning of Human Beings, 2008.
This paper argues that the cloning of human beings should be outlawed worldwide.
750 words (approx. 3.0 pages), 4 sources, MLA, $ 26.95

Abstract
In this article, the writer notes that cloning offers the prospect of scientists being able to create a new individual genetically identical to another person. The writer points out that the science to do this has almost been perfected. The writer notes that some people believe that cloning technology should be vigorously developed, as it offers an enormous potential to cure diseases and so reduce human suffering. However, this essay argues that this potential benefit is outweighed by the massive potential ethical problems. Therefore, it is argued that cloning of human beings should be outlawed worldwide.
From the Paper
"One compelling reason to ban cloning is with regard to the human rights of potential cloned beings. Things that are manufactured are usually, by definition, property, and so do not have human rights. Thus, if a company were to clone human beings, it could possibly have the power to use these people as "spare parts" for rich clients. This potential ethical minefield was explored in the recent film, The Island. In this film, rich people have clones made from their DNA, and "store" them in an underground facility. The clones have no idea they are clones - they think they are the survivors of a nuclear holocaust, kept confined for their own safety. When their "owners" become sick or are injured, the clones are simply killed to provide spare parts. The clones are even used for breeding purposes. In this way, a female customer of the clone company can "give birth" to her own genetic offspring without the inconvenience of being pregnant."
