Do binaural beats really work?

Binaural beats have been shown to ease and facilitate the process of meditation. The process is simple; two separate beats are played through a pair of headphones and the resulting effects on the brain depend on the beats combined. Other combinations have not been proven conclusively effective.There are a number of proposed and theoretical benefits to binaural beats. These include heightened mental acuity, dreamless sleep and general mood relaxation. They are tied to the frequency range at which the binaural beats are played and in what combinations, creating a theoretical sliding scale of pos..

What are the uses of oxygen?

Oxygen is a colorless, odorless and tasteless gas. It comprises 22 percent of air in the atmosphere and is part of the air that people breathe. Oxygen is found in the atmosphere, the human body, the sun and oceans.\nThe most important use of oxygen is sustaining life. All living organisms require oxygen to survive. Through aerobic respiration, energy is generated from food, allowing organisms to carry on with their daily activities. Oxygen is usually used in health care institutions to aid breathing in people with respiratory problems.\nThe main commercial application of oxygen is steel produc..

What is the difference between basalt and granite?

Granite is an intrusive rock that is formed when magma cools inside the crust. This slow cooling gives time for crystals to grow, making it more coarsely grained than an extrusive rock. This coarse grain makes granite a favorite of rock climbers. Basalt, on the other hand, has a smooth texture from rapid cooling, usually by water.\nGranite is a felsic rock, meaning that it has a high silicon content; it is mostly made out of quartz, mica and feldspar. Basalt, as a mafic rock, contains more calcium oxide, manganese oxide and iron compounds than granite. Its high iron content gives it magnetic p..

What are examples of anabolism and catabolism?

A person’s metabolism constitutes all of the physical and chemical activities in the body that use or covert energy. Metabolism comes in two forms: anabolism and catabolism. Catabolism breaks down and gives out energy the body needs for physical activity. Digestion is a catabolic activity because it takes food and breaks it down into small molecules. These molecules are then sent to other cells in the body to convert them to energy.\nAnabolism is the opposite of catabolism because it builds up molecules in the body. It makes bigger molecules out of smaller molecules. Anabolic activities incl..

How can people stop ozone depletion?

Ozone molecules consist of three oxygen molecules, and are an important protective part of Earth's atmosphere. Certain catalysts, such as hydroxyls, nitric oxide, chlorine and bromine atoms, have the ability to break the bonds of ozone molecules, effectively destroying them by converting the oxygen into other compounds. Compounds called chlorofluorocarbons, or CFCs, contain many of these catalysts, and are particularly dangerous to the ozone layer. The Montreal Protocol banned their use in 1989, although they are not the only source of potentially ozone-destroying compounds.\nAs of 2014, ..

What is the compound name of H2CO3?

One of the components of normal air is carbon dioxide, which accounts for around 300 parts per million of air. When air mixes with water, the carbon dioxide reacts with the water molecules and dissolves to form carbonic acid. However, only a very small percentage of the gas is actually present in true carbonic acid and the rest is regarded as dissolved carbon dioxide.

What are some everyday examples of equilibrium?

Equilibrium is achieved if all the forces acting on an object are balanced. There are various types of equilibrium depending on whether the context is physical, chemical or biological. An example of physical equilibrium is a car at rest. The force of gravity pulling the car toward earth is balanced by the force of the road pushing the car up. A car at a constant velocity is at equilibrium as well, since the force of friction is balanced by the force from the car's engine. When hot coffee cools down to room temperature, it is said to attain thermal equilibrium with the room since the amoun..

What was the Erwin Chargaff experiment?

There are two different categories of bases found in the structure of DNA: purines and pyrimidines. Chargaff's most famous experiment established that these two types of bases appeared in a one-to-one ratio. There are four different bases: adenine, thymine, guanine and cytosine. Chargaff was able to prove with his experiment that there was a one-to-one ratio between adenine and thymine and a one-to-one ratio between guanine and cytosine.\nChargaff examined DNA from different organs within the same organism and found that the ratios of the different components in their DNA was consistent a..

How do you define distilled water vs. spring water?

Spring water bubbles up to the surface without having to be pumped. Some companies that sell spring water get it from springs that have been flowing for hundreds or even thousands of years. More conscientious companies protect their springs in order to uphold their claims of purity and naturalness. However, the law requires that the trucks that pump the water and carry it to the bottling plant be chlorinated in some jurisdictions. The water might also undergo some treatment once it gets to the bottling plant for decontamination.\nSpring water that isn't filtered still isn't pure. Bec..

What is an excited state electron configuration?

For example, an atom in an excited state may contain two electrons in its 1s orbital, one electron in its 2s orbital and one electron in each of its 2p orbitals. Since the maximum possible number of electrons in the 2s orbital is two electrons, one of the electrons in a 2p orbital needs to move to the 2s orbital to return the atom to a ground state.
