What are some interesting facts about Mars?

A NASA probe, Mariner 9, discovered dormant volcanoes on Mars after the probe landed on the planet in 1971. Olympus Mons, a shield volcano on Mars, holds the record for the tallest mountain in the solar system, with a height of 21 kilometers.\nThe largest dust storms in the solar system occur on Mars. This is due to the fact that Mars possesses a more elliptical orbit than the other planets. Dust storms can cover the entire planet, and they can last for several months.\nMars possess two moons, Phobos and Deimos. Both moons are composed of materials similar to asteroids found in the solar syste..

Why is Nicolaus Copernicus famous?

Fortunately for modern astronomers, Copernicus possessed the strength of character necessary to endure the maelstrom that followed his announcement. Until then, it was standard thinking in the West culture, as well as a part of religious dogma, that God had set all things in motion in the manner outlined by Ptolemy. By contradicting Ptolemy's description of how the solar system functioned, Copernicus also contradicted the sincerely held beliefs of the Church and its adherents. He would later be excommunicated by the Church as a heretic, and many who took up his call would follow the same ..

What are types of distillation?

Simple distillation can be used when the liquids involved have several common properties. The liquids should be relatively pure with no more than 10 percent contaminants. The liquid should also have a non-volatile component, such as a solid. Finally, the liquid should be contaminated by a liquid that has a boiling point that differs by at least 70 degrees Celsius. When boiling points of two liquids are similar, simple distillation cannot be used. Instead, fractional distillation is the preferred method. Fractional distillation is used when differences in boiling points are less than 70 degrees..

In what part of the body does mitosis occur?

Mitosis is the replication of a single cell into two identical daughter cells. The original cell becomes obsolete, making the process a simple replication of a single cell. It is used in all areas of the body, but is especially important in the areas that need to have constant regeneration of cells. The skin is an example of an organ that has constant mitosis occurring due to a higher rate of cell loss as a result of environmental factors.\nThe DNA, or deoxyribonucleic acid, that is composed in the cells is exactly the same throughout the body. The DNA makes up what a person is and must not de..

What are the smells of esters?

Esters can be produced in a laboratory via a chemical reaction called esterification, which chemists carry out by combining alcohols with carboxylic acids. Benzyl acetate, for example, is produced using acetic acid and benzyl alcohol. Ethyl butyrate is derived from butyric acid and ethyl alcohol, while methyl salicylate is synthesized using salicylic acid and methyl alcohol. To carry out esterfication, chemists add heat to the appropriate carboxylic acids and alcohols in the presence of a dehydrating substance, such as concentrated sulfuric acid.\nChemistry students can carry out esterfication..

What are the different types of electricity?

Most power plants that run on fossil fuels, such as coal, gas or oil, burn the fuel to create steam. The steamis then used to spin massive turbines to create electricity. Nuclear power plants work in a similar way, except the heat comes from the splitting of radioactive atoms. Although nuclear power doesn't produce CO2 or other greenhouse gases, there are still concerns about its potential environmental impact.\nHydro and wind energy is also generated using turbines, which are powered by water and air respectively. Hydro power plants require a dam and a large reservoir of water, which pas..

Where do mahogany trees grow?

Mahogany was once abundant and covered a far larger area, but heavy logging reduced the natural range of mahogany in Honduras and Haiti. Logging has cut mahogany stocks in other countries, though not to the same dramatic extent. Some mahogany can be found in the extreme southern reaches of Florida, making these hardwood groves the only wild source of mahogany in the United States.

What is plasma when clotting proteins are removed?

Serum is separated from plasma after blood is donated. After the blood clots, it is placed in a centrifuge. This machine separates the blood and the blood-clotting materials, such as fibrogin and prothrombin, from the red blood cells.\nSerum is used to test for many medical conditions. Albumin and globulin, which are serum proteins, are the two components of serum measured to determine some diseases. The liver makes albumin, which can be tested for with a serum albumin test. This test can help diagnose kidney or liver disease.

What is a polymorph in geology?

Polymorphs are very common in geology. A popular example of carbon polymorphs are diamond and graphite. Breaking the word polymorph into smaller sections gives away the meaning of the word. "Poly" is a root word meaning many. "Morph" means to undergo a gradual transformation. The word "polymorph" essentially means many transformations, such as carbon being transformed to diamond or graphite.

Does oxygen support combustion?

As one of the most abundant elements on the planet, it is no surprise that 21% of the earth is made up of oxygen and the human body has around 65% of its mass made up of oxygen. Oxygen is essential for the life of animals and plants. Even fish and other underwater animals require oxygen and obtain their oxygen through the sources water provides.\n\nOxygen is one of the most unique gasses on the planet because it is so versatile. It is not only necessary for many things to live because it aids in respiration, but it is also essential for any type of combustion to occur. It is able to increase t..
