What is the purpose of recycling?

Recycling saves and conserves energy because it takes far less energy to reprocess recycled materials into new materials than to process virgin materials. For example, recycling paper to make new paper products takes less energy overall than creating new paper products from trees.\nRecycling also helps reduce global warming and reduce air pollution by reducing the industrial production of new goods. Recycling goods to make new goods saves energy and reduces the amount of industrial work that must be completed to create a new product. This reduces greenhouse gas emissions and, thus, reduces glo..

What is the scientific name of archaebacteria?

Many of the Archean microorganisms inhabit harsh environments. Thermophiles live in extreme heat, such as the hot springs of Yellowstone National Park, one of the first places where Archaea were discovered. Halophiles thrive in highly saline waters, while methanogens survive in spite of the methane they produce.\nArchaea do not exclusively live under extreme conditions. They can be found in the open sea among plankton.

What are the uses of water?

Water is useful to fight fires and is important in construction work. Concrete, for example, is made of cement and other materials mixed with water. Water has use as a coolant in manufacturing, industry and agriculture. Both livestock and crops need great volumes of water for survival, and crops need water to deliver fertilizer and insecticides.\nLong before the industrial age, people used water as a source of energy. The first machine to use water was most likely a platform built beside a stream that was attached to a bladed wheel. The water fell on the blades and turned the wheel. Old-fashio..

What is the food chain in the tundra biome?

Life in the tundra involves an inhospitable, cold temperature environment of rocky, treeless plains that encircle the north pole. The arctic tundra food chain, or web, starts with plants or primary producers, such as lichens, liverworts, fungus, mosses, grasses and small shrubs. They hug the ground because of extremely cold temperatures, low precipitation, wind and low-nutrient soil. The first level consumers who live off of the producers are the herbivore mammals, such as pika, musk ox, caribou, lemming and arctic hare. These herbivores in turn provide food for the second level consumers, th..

What is the melting point of plastic?

Plastics are polymers, or large molecules that are made up of many subunits. A polymer is a chain of the units carbon, hydrogen, oxygen and sometimes silicon. These components are polymerized together or "joined" together. Natural polymers can be found as tar, shellac, tortoise horns, tree sap amber and even latex. These polymers were processed and made into materials such as vulcanized rubber, celluloid and gun cotton.When the world went to war in World War II, the supply of natural polymers was cut off and many countries, including the United States, were forced to create their own polymers ..

What are types of plants in tropical rainforests?

Tropical rainforest plants exist at all levels of the forest biome, although most grow on the ground. Others, called aerial plants, live higher up on the branches or trunks of trees. They feature air roots, which absorb water and nutrients from the surrounding air.Regardless of where they live, tropical rainforest plants differ in physical appearance. Some, like strangler figs, exist as long, thin brown vines while orchids and bromeliads produce beautiful flowers. Some plants live harmoniously in their shared space, but others constantly compete for limited resources, particularly sunlight. Pl..

How many quarts are in a liter?

As of 2014, the United States is one of three countries that have not yet adopted the metric system. Instead, it uses a system based on the English units that were in common use when the United States declared its independence, and these units include the quart. Approximately 50 years after American independence, Great Britain revised its system of measurements to change the definitions of some units, causing discrepancies between U.S measurements and imperial units. In 1893, the Mendenhall Order redefined most of the customary units that the United States uses in terms of the metric system. T..

What are the functional groups present in the vitamin C molecule?

The hydroxyl group indicates that an OH, or hydroxide, has bonded to a carbon.The carbonyl double bond, two carbons bonded to each other, has an OH bond attached to each end of its two carbons. Last, its ester functional group indicates where two oxygen groups are bonded to a carbon. However, in this case, one of the oxygen molecules is double bonded to one end of the carbon, and the other is single bonded to the opposite end.\nAccording to the diagram of the structure of Vitamin C on the NCBI website, Vitamin C has several hydroxyl groups, which explains Vitamin C’s solubility. Since hydrox..

What does a ornithologist do?

Every aspect of a bird's life is studied by an ornithologist. This includes the history of the type of bird and how the current form evolved from its ancestors. Ornithologists study this evolution to have a better understanding of how birds have adapted to the environment and how future environmental changes might affect them. Some ornithologists focus on one bird type, while others study birds in general.

What is the cause of precipitation?

Water is not created or destroyed in significant quantities on Earth; instead, it moves around as part of the hydrologic cycle. When water rains down out of the clouds, it flows across the surface of the Earth. Some of it collects in ponds, lakes or rivers, while other raindrops end up being absorbed by the ground. Eventually, all of it makes its way to the world’s oceans.\nMost evaporation occurs over the oceans and the world’s largest lakes and reservoirs. However, as that air starts to rise, it begins to cool. When it cools enough, the water must leave the gaseous phase and become a liq..
