Maine - geography.
temperatures range from 17° to 21°C (62° to 70°F) with the southern interior being the warmest and the east coast and north the coolest. However, daytime summertemperatures may reach the lower 30°s C (lower 90°s F), and temperatures in winter have fallen as low as -44°C (-48°F) in the interior. D2 Precipitation Precipitation (rainfall and snowfall) in Maine is evenly distributed throughout the year. Most areas receive from 860 to 1,020 mm (34 to 40 in) yearly, although parts ofthe coast are som...

Whale - biology.
III BEHAVIOR OF WHALES Studies of whales in captivity have taught scientists much about the complex social behavior of whales. Since the late 1980s, advances in the use of satellite trackingsystems have also broadened opportunities for scientists to observe how whales behave in the wild. A Swimming and Diving Whales swim by making powerful up-and-down movements of the tail flukes, which provide thrust. The power comes from body muscles that flex the lower spine upand down in a wavelike motion...

Pottery
I
INTRODUCTION
Pottery, clay that is chemically altered and permanently hardened by firing in a kiln.
basket, or a clay or plaster form. Liquid clay can be poured into plaster molds. A pot can be coil built: Clay is rolled between the palms of the hands and extended intolong coils, a coil is formed into a ring, and the pot is built up by superimposing rings. Also, a ball of clay can be pinched into the desired shape. The most sophisticatedpottery-making technique is wheel throwing. The potter's wheel, invented in the 4th millennium BC, is a flat disk that revolves horizontally on a pivot. Both...

Evolution - biology.
genetic diversity to extinction. Sexual reproduction ensures that the genes in a population are rearranged in each generation, a process termed recombination. Although the combinations of genes inindividuals change with each new generation, the gene frequency, or ratio of different alleles in the entire population, remains relatively constant if no evolutionaryforces act on the population. One such force is the introduction of new genes into the genetic material of the population, or gene pool...

From the point where theColumbia first touches the state, at Wallula Gap, the river runs in a shallow gorge, deepening as it approaches the Cascades.

The area west of the Cascades, which is exposed throughout the year to rain-bearing winds from the Pacific Ocean, has a temperate marine type of climate that is characterized by mild wet winters and cool summers. The Cascades prevent themoist air blowing in from the Pacific from reaching eastern Washington. The Rocky Mountains on the eastern border also represent a climatic barrier.

A la fin du xixe siècle, Oscar Wilde écrivait dans la préface au Portrait de Dorian Gray : « L'appellation de livre moral ou immoral ne répond à rien. Un livre est bien écrit ou mal écrit. Et c'est tout. [...] L'artiste peut tout exprimer. » le Portrait de Dorian Gray, traduction Jaloux-Frapereau, Stock, 1925, p. 10. A l'aide d'exemples précis, et sans vous limiter forcément à la littérature, vous commenterez et discuterez cette opinion. ?
hautes valeurs éthiques.Pour G. Sand, dans la préface de La Mare au Diable, l'art a « une mission de sentiment et d'amour », « le romand'aujourd'hui devrait remplacer la parabole et l'apologue des temps naïfs ». Elle se plaint que la peinture de truands,fréquente dans les romans d'Eugène Sue, dresse les riches contre les pauvres, en instaurant la peur. Il faut aucontraire faire aimer les miséreux : La Mare au Diable raconte comment un riche laboureur ému par une sauvageonnefinit par l'épouser....

Eagle - biology.
States, is a member of this group found only in North America. It is named for its snow-white head. However, the name bald does not refer to a lack of feathers but comes instead from an outdated word meaning marked with white, as in piebald. The adult bald eagle is blackish brown, with a white head and tail. Its bill, legs, and feet are bright yellow. The bill, which is longer and heavier than the gray bill of golden eagles, is useful for piercing the skin of fish. Bald eagles vary in size....

From The Scarlet Letter - anthology.
“Mercy on us, goodwife,” exclaimed a man in the crowd, “is there no virtue in woman, save what springs from a wholesome fear of the gallows? That is the hardestword yet! Hush, now, gossips; for the lock is turning in the prison-door, and here comes Mistress Prynne herself.” The door of the jail being flung open from within, there appeared, in the first place, like a black shadow emerging into the sunshine, the grim and grisly presence ofthe town-beadle, with a sword by his side and his staff...

Pablo Picasso.
Color juxtapositions—between blue and orange, for instance—are intentionally strident and unharmonious. The representation of space is fragmented and discontinuous. While the left side of the canvas is largely Iberian-influenced, the right side is inspired by African masks, especially in its striped patterns and oval forms. Suchborrowings, which led to great simplification, distortion, and visual incongruities, were considered extremely daring in 1907. The head of the figure at the bottom right,...

Shark - biology.
Sharks have two-chambered hearts that are relatively small compared to the rest of their bodies. Blood flows from the heart to the gills, where it collects oxygen fromwater and then distributes it to the other organs and tissues. The small heart produces weak blood pressure, and many sharks must swim continuously to create themuscular contractions needed to circulate blood throughout their bodies. Most sharks are cold-blooded—that is, they do not generate heat by digesting food. Instead, the bod...
