INTRODUCTION
Dog, mammal generally considered to be the first domesticated animal.
French word for butterfly because it has ears that resemble butterfly wings, is a happy, friendly dog, suitable for small living spaces. The final dog group, nonsporting ,includes a wide variety of purebreds that differ in size, coat, overall appearance, and personality, from the shorthaired spotted dalmatian to the curly-haired poodle. V DOG BEHAVIOR Instinctive behaviors of the domestic dog are comparable to those of its wild relatives, the wolf, coyote, fox, and jackal. Unlike trained behavi...

The child develops the disease only if he or she receives amutated allele from each parent. When both parents are carriers, there is a 25 percent chance that a child will be disease-free, a 25 percent chance that it will have thedisease, and a 50 percent chance that it will be a carrier. Examples of genetic diseases that follow the dominant-recessive pattern include sickle-cell anemi...

European patterns of living. People of mixed African and European ancestry form a distinct group in Guyana, maintaining closer social ties to the European communitythan to the African Guyanese community. Asians from the Indian subcontinent began to arrive in the 19th century, following the abolition of slavery in Guyana, to work as indentured and contract laborers. Theycontinued to arrive until 1917, when Britain outlawed indentured servitude. Thousands of Indians chose to remain in Guyana after...

2 évolutionniste. La grande diversité des espèces vivantes est le fruit d’un changement durant lequel, à partir d’un ancêtre commun unique, se sont produites des ramifications, des bifurcations, des impasses et des modifications dans la même ligne évolutive. Et ce sont précisément le changement et la bifurcation de la ligne évolutive des organismes qui sont les principaux thèmes abordés par la théorie évolutionniste. Une autre notion fondamentale de la théorie évolutive est celle d’adaptation....

Electricity

INTRODUCTION
Electricity, one of the basic forms of energy.
electrons in the neutral object are attracted to the positive object. Some of these electrons flow to the side of the neutral object that is nearest to the positive object.This side of the neutral object accumulates electrons and becomes negatively charged. Because electrons leave the far side of the neutral object while its protonsremain stationary, that side becomes positively charged. Since the negatively charged side of the neutral object is closest to the positive object, the attraction bet...

Gambling.
C Lotteries Lotteries are another form of gambling. In a lottery, tickets are sold for a set amount and a share of the proceeds is returned to the winners, usually through a randomdraw. Most games allow players to pick their own numbers or let a computer randomly pick for them. Lotteries offer a wide variety of games, including weekly drawings,instant “scratch” tickets, daily games, and superlottos with prizes increasing until there is a winner. Large lottery prizes sometimes exceed $100 millio...

La ZEE française s'étend sur 11 millions km2, elle est la 2eme plus grande mondiale derrière les Etats-Unis. La France a le monopole de l'exploitation des ressources de cette ZEE, notamment halieutique dans le cas de l'agriculture. Elle bénéficie d'une triple ouverture maritime, ce qui propice à l'exportation des denrées agric...

Dans Lire le théâtre, Anne Ubersfeld souligne l'importance de la mise en scène pour révéler les potentialités du texte théâtral : la représentation est la somme de T (le texte) et T' (la mise en scène); elle précise que le texte au théâtre est troué, laisse des vides; et c'est à la représentation de combler ces vides. La notion de genre comique complexifie cette réflexion : s'il est évident que la mise en scène permet de déployer le texte, encore faut-il se demander dans quel sens elle le déploi...

Virtually all snakes and lizards display yet another variation of internal fertilization. Located in the tail are two penises, called hemepenes, which are covered by spinesand knobs that help lock it into place during mating. The male uses one hemepene at a time for copulation. Male salamanders secrete large...

Acquired Immunodeficiency Syndrome.
child transmission is particularly prevalent in Africa. D Misperceptions About HIV Transmission The routes of HIV transmission are well documented by scientists, but health officials continually grapple with people’s unfounded fears concerning the potential for HIVtransmission by other means. HIV differs from other infectious viruses in that it dies quickly if exposed to the environment. No evidence has linked HIV transmission tocasual contact with an infected person, such as a handshake, huggi...

L'Experience N'Est-Elle Qu'Empirique?
I – D’après les positions idéalistes, tout étant esprit, l’expérience humaine n’a jamais rien d’empirique car elle est le reflet des idées absolues.

En outre, comme on estime que ces mêmes forêts perdront 90 % de leur surface au cours du prochain demi-siècle, si aucun frein n'est mis à leur destruction actuelle, il est possible d'estimer à plusieurs millions le nombre d'espèces vivantes que l'homme fera disparaître d'ici là. Au strict point de vue scientifique, les conséquences de l'extinction accélérée d'un aussi grand nombre d'espèces seront catastrophiques pour la recherche scie...

Mental Retardation.
For example, measles, chicken pox, and whooping cough may lead to encephalitis and meningitis, which can damage the brain. Physical trauma to the brain can also cause mental retardation. Brain damage may result from accidental blows to the head, near drowning, severe child abuse, andchildhood exposure to such toxins as lead and mercury. Experts believe that poverty and a lack of stimulation during infancy and early childhood can be factors inmental retardation. Children raised in poor environmen...

Business.
The most common form of ownership is a sole proprietorship —that is, a business owned by one individual. At the beginning of the 21st century, there were more than 17 million sole proprietorships in the United States. These businesses have the advantage of being easy to set up and to dissolve because few laws exist to regulatethem. Proprietors, as owners, also maintain direct control of their businesses and own all their profits. On the other hand, owners of proprietorships are personallyrespon...

Population.
year AD 1, and it took more than 1,500 years to reach the 500 million mark. Growth was not steady but was marked by oscillations dictated by climate, food supply, disease, and war. Starting in the 17th century, great advances in scientific knowledge, agriculture, industry, medicine, and social organization made possible rapid acceleration inpopulation growth. Machines gradually replaced human and animal labor. People slowly acquired the knowledge and means to control disease. By 1900 the worldp...

The most significant of these rules stated that colonial powers were obligated to notify each other when they claimed African territory.Further, subsequent “effective occupation” of the claimed area was necessary for the claim to remain valid. Through it all, as Europeans negotiated their rights toAfrican territory, not a single African was present. Once the conference was over, it was clear that a European Scramble for African territories was underway. Southern Afr...

Antelope - biology.
antelopes still display complex patterns of behavior, although much of it is instinctive rather than learned. In open habitats, antelopes run a high risk of predation (being preyed upon). To survive they use several kinds of defensive strategy, including living in herds. Herd living ensures that many pairs of eyes and ears are on the alert for danger. Herd living also gives individuals a better chance of avoiding attack, because predators canchoose from many potential targets. When danger thre...

Lion - biology.
Lions usually hunt at night, alone, or in groups. Their preferred prey are large hoofed mammals, such as zebras and wildebeests, but they will go after small hares aswell as huge giraffes. Typically, a lion hunting alone will slowly and silently stalk its prospective victim, trying not to be seen, until it is about 30 m (about 98 ft) away.Then with a burst of speed, the lion will run toward the prey, grab it, and throw it to the ground. The lion kills the prey by biting the back of the animal’s...
