• Galaxy - astronomy.

  Astronomers have obtained images of young galaxies using the Keck Telescope in Hawaii and the Hubble Space Telescope, which resides in an orbit high above Earth’satmosphere and thus avoids atmospheric interference. Photos from the HST show galaxies that are as far as 13 billion light-years away from Earth, which means theyformed soon after the universe formed about 13.7 billion years ago. The galaxies appear to be spherical in shape, and may be early precursors of elliptical and spiralgalaxies....

• Metabolism (chemistry) - biology.

  nearly perfect balance. Although much remains to be revealed about metabolic processes, biochemists now agree that regulatory, or rate-limiting, enzymes figure largely in the reactionsinvolved ( see Enzyme). Affecting metabolic pathways at the earliest steps, each enzyme molecule has a specific, or active, site that matches, or “fits,” its particular substrate—the compound with which the enzyme forms a product. The precision with which rate-limiting enzymes and substrates join to set off a parti...

• Antarctica - geography.

  The geographic South Pole lies near the center of the continent in East Antarctica. This point is where all map lines of longitude converge at the southern end ofEarth’s axis of rotation. Distinct from the geographic south pole is the south magnetic pole, where the lines of force of Earth’s magnetic field emerge vertically,arching upward over the planet to enter Earth again at the north magnetic pole. The south-seeking end of a compass needle points to the south magnetic pole. Thesouth magnetic...

• Homosexuality.

  that “the history of our nation has demonstrated that separate is seldom, if ever, equal,” in affirming that homosexuals are entitled to the same rights of marriage asheterosexuals.

• baudelaire analyse L'ennemi

  Baudelaire highlighting the time that passes through a progression from the past to the present, the discouraging record of this stormy youth is underlined by the past composed «on fait» (vers 3) and by the proposition of consequence to the present. The metaphor continues in the mention of a nature which has undergone the meteorological elements in their destructive character, the past having left traces: a life ravaged by «le tonnerre et la pluie», by the blows of fate and the daily g...

• Honey Bee - biology.

  B Reproduction and Development The queen controls the sex of her offspring. When an egg passes from her ovary to her oviduct, the queen determines whether the egg is fertilized with sperm from thespermatheca. A fertilized egg develops into a female honey bee, either worker or queen, and an unfertilized egg becomes a male honey bee, or drone. The queen lays the eggs that will develop into more queens in specially constructed downward-pointing, peanut-shaped cells, in which the egg adheres to the...

• Greenhouse Effect.

  addition, humans cut down huge tracts of trees for lumber or to clear land for farming or building. This process, known as deforestation, can both release the carbonstored in trees and significantly reduce the number of trees available to absorb carbon dioxide. As a result of these human activities, carbon dioxide in the atmosphere is accumulating faster than Earth’s natural processes can absorb the gas. By analyzing airbubbles trapped in glacier ice that is many centuries old, scientists have d...

• Neptune (planet) - astronomy.

  The gaseous atmosphere of Neptune contains hydrogen, helium, and about 3 percent methane. It extends about 5,000 km (about 3,000 mi) above the planet’s ocean.Light reflected from Neptune’s deep atmosphere is blue, because the atmospheric methane absorbs red and orange light but scatters blue light. In 1998 astronomersalso identified molecules of methyl in Neptune’s atmosphere. Methyl molecules each contain one carbon atom and three hydrogen atoms. Methyl molecules are knownas hydrocarbon radical...

• Protestantism.

  F England The Anglican Church became the established church in England when Henry VIII assumed (1534) the ecclesiastical authority over the English church that had previouslybeen exercised by the pope.

It is a comfort to hope, as so many of the world's sorrows and wrongs have, from age to age, been lived down, so a ti...

• Protests in the 1960s - U.

  E Youth Culture Young people played an important role in the movements for social change during the 1960s.

  Consider, for instance, the concept of ‘cause', which appears in Kant's list of categories. If it is a priori thenexperience cannot be cited as its origin; indeed, experience – as Hume had shown – could never establish thenecessity and universality of the link binding cause and effect together. No doubt our experience does suggest tous various generalizations. But might there not be a world of experience in which such great chaos reigned thatnothing could be identified as cause and ef...
