The physicists Isaac Newton and Albert Einstein are most responsible for the modern interpretation of gravity. The Newtonian description came about when Newton realized that the same force that causes objects to return to the ground when thrown on Earth, keeps the moon in orbit. The more massive the object, the more gravity it commands. The Earth is much larger than we are, so its gravity dominates our interaction.\nAlbert Einstein extended the knowledge of gravity further, with his realization that energy matters just as much as mass, and that gravity is the curvature of space-time. The benef..
What are the benefits of scrap metal recycling?

A 2011 survey indicates that the scrap metal Industry employed over 450,000 workers in the United States and created $10.3 billion in revenue for governments throughout the country, says Forbes. States with larger populations, such as New York, California, Texas and Florida, prosper the most when it comes to employment and revenue in this industry.\nIn order to remove ore from the earth, fossil fuels power the equipment necessary to extract it. Metal recycling still requires some fossil fuel usage, but not nearly as much. Energy savings range from 56 to 92 percent, says About.com.\nRecycling 2..
Where are insects on the food chain?

Some insects feed on all foods available, consuming a variety of plants and organic matter, while others classify as specialized feeders. These insects rely exclusively on a few select items for food. In consuming decaying and decomposing matter, insects play a large role in keeping environments clean. They break down and decompose waste products, which would otherwise accumulate quickly. In addition to consuming many types of earthen materials, insects serve as sustenance for many animal species. They provide amphibians, reptiles, birds and some mammals with a critical source of food. Some hu..
What are vestigial wings?

Vestigial wings are the result of a mutation in the fly's genes. The mutation directly affects wing development without affecting the overall growth and development of the fly. The mutation causes the wings to form as short, crumpled stubs, and may be the result of the temperature they endured in their hatching stage. The vestigial gene is recessive, and the mutation may only occur if both parent flies carried the mutation in their genes.

Domains Archaea and Bacteria consist of bacterial species called prokaryotes that have no organelles. Domain Eukarya represents more complex organisms that have evolved from the prokaryotes.\nProtists are the simplest eukaryotes, consisting of single-celled organisms such as algae and amoebas. The fungi can be either unicellular or multicellular and obtain their food by absorbing nutrients from their environment. Plants are multicellular and can make their own food. Animals are also multicellular organisms, but they must consume food to obtain energy.

Nitrogen is atomic number 7, which means it is made up of 7 protons and 7 electrons. It is the most abundant element in the Earth's atmosphere, taking up around 78 percent by volume of dry air. The Random House Dictionary lists ammonia, cyanide, fertilizer, dyes and cooling agents as common substances made from nitrogen.
What are some facts about the heart?

The heart includes four sections, called chambers, according to the National Heart, Lung, and Blood Institute. The upper chambers are called atria, while the lower chambers are known as ventricles. The heart also has four valves, which make sure that the blood only flows in one direction: in or out.\nWhen the heart muscle contracts, the chambers shrink and push oxygen-rich blood into the blood vessels, explains the National Heart, Lung, and Blood Institute. When the heart relaxes, the chambers expand again and allow the return of oxygen-poor blood. If the heart stops its pumping, the blood is..
What is the chemical formula for salt?

Salt is an ionic compound made up of sodium and chloride ions. Sodium is an electron donor because it tends to give away the single electron in its outermost energy level. On the other hand, chlorine is an electron acceptor; with seven electrons in its outermost energy level, chlorine needs one more electron to achieve a stable configuration. Once an electron is transferred from sodium to chlorine, a positive sodium ion and a negative chlorine ion are formed. These two opposite charges attract one another. The strength of this ionic bond yields the crystalline structure of salt and gives it a ..
How do stratovolcanoes erupt?

The stratovolcano has an easily recognizable cone shape. Mount Fuji in Japan and Mount St. Helens in Washington are two examples of picturesque stratovolcanoes. The eruption of Mount St. Helens on May 18, 1980, which led to the destruction of over 230 square miles of forest and the death of 57 people, demonstrated the sheer power of stratovolcanoes.\nThe build up of pressure in the magma chamber causes the violent eruption seen in these volcano types. When magma reaches the conduit, the pressure is released, which causes the gases to explode in an extremely violent manner. Most active stratovo..
What is the scientific meaning of a scavenger?

In general, an animal classified as a scavenger is a carnivore, or a meat eater. That said, some scavengers also eat dead or decaying plant matter. Most, however, are familiar with scavengers that consume dead and decaying animals. Scavengers hold an important role in the food web as they keep their ecosystem clean by disposing of decaying matter. These animals break down the organic material and recycle it into the ecosystem.The food web is a depiction of which animals eat other animals, and it is grouped into different levels based on nutrition.The first and most basic level is made up of au..
