Please answer the following question: Information: - The Red River (American English: Red River of the North) is a North American river. Originating at the confluence of the Bois de Sioux and Otter Tail rivers between the U.S. states of Minnesota and North Dakota, it flows northward through the Red River Valley, forming the border of Minnesota and North Dakota and continuing into Manitoba, Canada. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into the Hudson Bay. - A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a number of roles in the environment, principally water purification, flood control, carbon sink and shoreline stability. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life. - Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. - Kellys Slough National Wildlife Refuge was established to develop and manage a system of wetlands and grasslands that is unique to the Red River Valley . The Refuge supports a diversity of wetland and grassland wildlife , while providing for wildlife - dependent recreation , interpretation , and education . Kellys Slough National Wildlife Refuge is located in the heart of the Red River Valley . The Refuge contains an intermittent stream that flows into the Turtle River , a tributary of the Red River . The Refuge covers portions of Blooming , Lakeville and Rye Townships of Grand Forks County . The refuge was established in 1936 and contains a total of 1,270 acres ( 5.1 km2 ) . - Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. - Manitoba is a province at the longitudinal centre of Canada. It is one of the three prairie provinces (with Alberta and Saskatchewan) and Canada's fifth-most populous province with its estimated 1.3 million people. Manitoba covers with a widely varied landscape. The province is bordered by the provinces of Ontario to the east and Saskatchewan to the west, the territories of Nunavut to the north, and Northwest Territories to the northwest, and the US states of North Dakota and Minnesota to the south. - Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is HO, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity. - North Dakota (locally ) is the 39th state of the United States, having been admitted to the union on November 2, 1889. - An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces (although some scientists say that the entire planet is an ecosystem). - North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea. - The number and type of plants, how leafy they are, and how healthy they are. In places where foliage is dense and plants are growing quickly, the index is high, represented in dark green. Regions where few plants grow have a low vegetation index, shown in tan. The index is based on measurements taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Terra satellite. Areas where the satellite did not collect data are gray. - The Red River Valley is a region in central North America that is drained by the Red River of the North; it is part of both Canada and the United States. Forming the border between Minnesota and North Dakota (when these territories were admitted as states in the United States, this fertile valley has been important to the economies of these states and to Manitoba, Canada. - Minnesota (locally ) is a state in the midwestern and northern regions of the United States. Minnesota was admitted as the 32nd U.S. state on May 11, 1858, created from the eastern half of the Minnesota Territory. The state has a large number of lakes, and is known by the slogan "Land of 10,000 Lakes". Its official motto is "L'Etoile du Nord" (French: "Star of the North"). Minnesota is the 12th largest in area and the 21st most populous of the U.S. states; nearly 60 percent of its residents live in the MinneapolisSaint Paul metropolitan area (known as the "Twin Cities"), the center of transportation, business, industry, education, and government and home to an internationally known arts community. The remainder of the state consists of western prairies now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed and settled; and the less populated North Woods, used for mining, forestry, and recreation. Minnesota is known for its progressive political orientation and its high rate of civic participation and voter turnout. Until European settlement, Minnesota was inhabited by the Dakota and Ojibwe/Anishinaabe. During the 19th and early 20th centuries, the large majority of the European settlers emigrated from Scandinavia and Germany, and the state remains a center of Scandinavian American and German American culture. In recent decades, immigration from Asia, the Horn of Africa, and Latin America has broadened its historic demographic and cultural composition. Minnesota's standard of living index is among the highest in the United States, and the state is also among the best-educated and wealthiest in the nation. - Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton. - Carbon (from "coal") is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalentmaking four electrons available to form covalent chemical bonds. Three isotopes occur naturally, C and C being stable, while C is a radioactive isotope, decaying with a half-life of about 5,730years. Carbon is one of the few elements known since antiquity.
