Political Parties.
In both Britain and the United States, competition between political parties undermined traditional conceptions of politics rooted in classical and Christian notions ofvirtue and public service. According to this tradition, political leaders should act according to a model of virtue that involved placing the common good above theinterests of a fraction of the society. Leaders acting to benefit only themselves or a narrow portion of the society were considered corrupt. However, party competitionr...

of water in the stomach or hump as was once commonly believed. Unlike other mammals, however, the camel can survive as long as three weeks without drinking,depending on the water content of its food. It can survive a water loss of about 40 percent of its normal body weight. In comparison, a loss of 15 percent is usually fatalfor humans. Camels can go without water due to several unique adaptations to their environment. The camel conserves more water in its body than any other mammal. It excretes...

Digestive System.
The stomach, located in the upper abdomen just below the diaphragm, is a saclike structure with strong, muscular walls. The stomach can expand significantly to storeall the food from a meal for both mechanical and chemical processing. The stomach contracts about three times per minute, churning the food and mixing it with gastricjuice. This fluid, secreted by thousands of gastric glands in the lining of the stomach, consists of water, hydrochloric acid, an enzyme called pepsin, and mucin (the...

Assisted Suicide.
regardless of the fairness of the procedures used (substantive due process). In the Glucksberg case, the Court indicated that the liberty interest protected by the 14th Amendment does not encompass the right to determine the timing and manner of one’s own death. The Court’s decision means that each state may determine whetheror not to prohibit or permit (and otherwise regulate) assisted suicide. In 2006 the Court upheld Oregon’s law permitting physician-assisted suicide. In a 6-to-3 decision,...

Warren G.
In his few campaign speeches, Harding relied mainly on the political effectiveness of bland generalities. Sometimes his statements were deliberately confusing. Forexample, he promised internationally minded voters that he would support an “association of nations,” while at the same time he promised “America first!” toisolationists. In this way he won the support of influential Republicans who believed in the League of Nations as well as those who opposed it. Harding's inoffensive standon the lea...

Native American writer Leslie Marmon Silko is perhaps best known for her first novel, Ceremony (1977), a coming-of-age
story about a young man of mixed Native American and white ancestry.
SequoyahNative Americans did not use a complex written language before the immigration of Europeans to the Americas. In theearly 1820s the Cherokee leader Sequoyah developed an alphabet and written language for his native tongue. ManyCherokee learned the new written language readily, and in 1828 they published the first Native American newspaper,written in both Cherokee and English.THE BETTMANN ARCHIVE Before Native Americans came into contact with Europeans, many tribes supplemented the spoken...

“Yes, dear ma'am,” said Mrs. Croft, “or an uncertain engagement, an engagement which may be long. To begin without knowing that at such a time there will be themeans of marrying, I hold to be very unsafe and unwise, and what I think all parents should prevent as far as they can.” Anne found an unexpected interest here. She felt its application to herself, felt it in a nervous thrill all over her; and at the same moment that her eyes instinctivelyglanced towards the distant table, Captain Wen...

naturally flaps down so as to increase lift. Flapping allows the differences in lift caused by uneven rotor tip speed to cancel out, producing a stable ride. Many helicoptersuse mechanical hinges with lubricated bearings, but some use flexible straps made of a composite material in order to reduce the required maintenance. Helicopters require different amounts of lift and thrust at different times during flight, because the aerodynamic forces acting on them change during hovering andacceleration...

Rutherford when he allowed an alpha-emitting substance to decay near an evacuated thin-glass vessel. The alpha particles were able to penetrate the glass and werethen trapped in the vessel, and within a few days the presence of elemental helium was demonstrated by use of a spectroscope. Beta particles were subsequentlyshown to be electrons, and gamma rays to consist of electromagnetic radiation of the same nature as X rays but of considerably greater energy.

Carbon - chemistry.
Graphite is black and slippery and conducts electricity. In graphite, the atoms form planar, or flat, layers. Each layer is made up of rings containing six carbon atoms.The rings are linked to each other in a structure that resembles the hexagonal mesh of chicken wire. Each atom has three sigma bonds (with 120° between any two ofthe bonds) and belongs to three neighboring rings. The fourth electron of each atom becomes part of an extensive pi bond system. Graphite conducts electricity,because th...

strong enough to kill potential predators. C Hearing, Vision, and Vocalizations Amphibians rely on their senses to find food and evade predators. Amphibians lack external ears but have well-developed internal ears. Hearing is most acute in frogs,which typically have a middle ear cavity for transferring sound vibrations from the eardrum, or tympanum, to the inner ear. Frogs and toads also use their keen hearingin communicating with one another. Using a true voice box, or larynx, and a large, exp...

Slavery in the United States - U.
tripled, from about 1.2 million to almost 4 million in 1860. The natural growth of the slave population meant that slavery could survive without new slave imports. Natural population growth also hastened the transition from an African to an African American slave population. By the 1770s, only about 20 percent of slaves in thecolonies were African-born, although the concentration of Africans remained higher in South Carolina and Georgia. After 1808 the proportion of African-born slavesbecame tin...

Protests in the 1960s - U.
E Youth Culture Young people played an important role in the movements for social change during the 1960s. Numbers alone made them important; more than 76 million babies wereborn during the post-World War II “baby boom.” In addition, these young people spent more years in school and were more affluent than previous generations. In theearly 20th century, most young Americans had moved quickly from childhood to adulthood. In the 1920s only 1 in 5 Americans graduated from high school, and almostal...

Earthquake.
III CAUSES Most earthquakes are caused by the sudden slip along geologic faults. The faults slip because of movement of the Earth’s tectonic plates. This concept is called theelastic rebound theory. The rocky tectonic plates move very slowly, floating on top of a weaker rocky layer. As the plates collide with each other or slide past eachother, pressure builds up within the rocky crust. Earthquakes occur when pressure within the crust increases slowly over hundreds of years and finally exceeds...
