The causative agent, a virus called poliovirus, enters the body orally, infecting the intestinal wall. It may proceed to the blood stream and into the central nervous system causing muscle weakness and often paralysis.

It is also the single largest genus within the family Vespidae, with over 300 recognized species and subspecies. Their innate preferences for nest-building sites leads them to commonly build nests on human habitation, where they can be very unwelcome; although generally non-aggressive, they can be provoked into defending their nests.
	Politeness Politeness is best expressed as the practical application of good manners or etiquette. It is a culturally defined phenomenon, and what is considered polite in one culture can often be quite rude or simply strange in another. While the goal of politeness is to make all of the parties relaxed and comfortable with one another, these culturally defined standards at times may be manipulated to inflict shame on a designated party.

Bosses may dictate voting patterns, control appointments, and wield considerable influence in other political processes. They do not necessarily hold public office themselves.

In democracy, political campaigns often refer to electoral campaigns, wherein representatives are chosen or referenda are decided. Political campaigns also include organized efforts to alter policy within any institution.
	Political machine A political machine is an unofficial system of politics organization based on patronage, the spoils system, "behind-the-scenes" control, and longstanding political ties within the structure of a representative democracy. Machines sometimes have a boss, and always have a long-term corps of dedicated workers who depend on the patronage generated by government contracts and jobs.
	Political party A political party is an organization that seeks to attain politics power within a government, usually by participating in electoral campaigns. Parties often espouse a certain ideology, but may also represent a coalition among disparate interests. In parliamentary systems of government, most political parties have an elected leader who, if his or her party is elected by absolute majority, or with a relative majority within the coalition where tradition is thus, becomes head of government.

	Pollination Pollination is an important step in the reproduction of seed plants: the transfer of pollen to the plant carpel, the structure that contains the ovule. The receptive part of the carpel is called a carpel in the flowers of flowering plants and a micropyle in gymnosperms.
	Pollinator A pollinator is the biotic agent that moves pollen from the male anthers of a flower to the female carpel of a flower to accomplish fertilization or syngamy of the female gamete in the ovule of the flower by the male gamete from the pollen grain. Though the terms are sometimes confused, a pollinator is different from a pollenizer, which is a plant that is a source of pollen for the pollination process.
	Polling station A polling station or polling place is where voters attend to cast their ballot in an election as part of the secret ballot process in a democracy or republic. Since elections generally take place over a one- or two-day span on a periodic basis, often annual or longer, polling stations are often located in facilities used for other purposes, such as schools, stadium or local government offices, and will each serve a similar number of people.
	Pollinium Pollinium, or plural pollinia, is a coherent mass of pollen grains. They are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in various plants, such as orchids and some species of the milkweed family Asclepiadaceae.

In social anthropology, polygamy is the practice of marriage to more than one spouse simultaneously . Like monogamy, the term is often used in a de facto sense, applying regardless of whether the relationships are recognized by the state .
	Polygon A polygon is a closed curve plane path composed of a finite number of sequential line segments. The straight line segments that make up the polygon are called its sides or edges and the points where the sides meet are the polygon's vertices. If a polygon is simple polygon, then its sides constitute the boundary of a polygonal region, and the term polygon sometimes also describes the interior of the polygonal region or the union of both the region and its boundary.

The above measurements are posited to be indicators of anxiety that accompanies the telling of lies.
	Polygyny The term polygyny is used in related ways in social anthropology and sociobiology. In social anthropology polygyny refers to the practice of a man having more than one wife at the same time. This is the most common form of polygamy. Polygynous marriage must be differentiated from polygamy in sexual partners.

The term is derived from the Greek words: polys meaning many, and meros meaning parts . The key feature that distinguishes polymers from other molecules is the repetition of many identical, similar, or complementary molecular subunits in these chains.

	Polynomial In mathematics, a polynomial is an expression in which a finite number of constants and variables are combined using only addition, subtraction, multiplication, and positive whole number exponents . Thus, is a polynomial, is not a polynomial. A polynomial function is a function defined by expression a polynomial.
	Polyp In zoology, a polyp is one of two forms of individuals found in many species of cnidarians. The two are the polyp or hydroid and the medusa . Polyps are approximately cylindrical, elongated on the axis of the body. One end is usually attached and the other bears the mouth, surrounded by a circlet of tentacles.

Most members of this family have their hymenium in vertical pores on the underside of the caps, but some of them have gills or gill-like structures.
	Polyporus squamosus Polyporus squamosus is an edible basidiomycete bracket fungus, with common names including Dryad's saddle and pheasant's back mushroom. The name "Dryad's saddle" refers to creatures in Greek mythology called Dryads who could conceivably fit and ride on this mushroom, whereas the pheasant's back analogy derives from the pattern of colours on the bracket matching that of a Common Pheasant back.
