How many stars are there in the Pisces constellation?

Pisces is a large constellation spanning approximately 890 square degrees of sky and is made up of a number of faint stars, with none brighter than a magnitude of 4. Noteworthy deep-sky objects that can be found within the constellation include the Pisces Dwarf Galaxy, as well as a number of spiral and irregular galaxies. These can be seen with the aid of instruments.

What are the properties of lipids?

All lipids are composed of a number of basic units known as fatty acids. These fatty acids are hydrocarbon chains with oxygen-hydrogen ends, making individual fatty acids hydrophobic at one end and hydrophilic at the other. This is why soaps made by processing normal lipids both dissolve in water and emulsify lipids. Cell membranes are made from phospholipid bilayers — two layers of lipids with hydrophobic ends facing the cell's exterior and interior — but hydrophilic ends facing each other within the membrane.\nMost lipids, however, are structured so that any polar hydrophilic areas ..

What is the equivalent of 50 milliliters in U.S. fluid ounces?

The fluid ounce is different from the ounce, which is used to measure mass. However, the term fluid ounce may be shortened to just ounce when the context makes its meaning obvious. Traditionally, the fluid ounce refers to the volume occupied by liquid substances such as wine and water in the United Kingdom. The ounce used for these measurements were varied as and is dependent on the liquid that is being measured such ounces for measuring wine or ounces for measuring ale.The ounce was standardized in 1824 by the British Parliament with the imperial gallon being the volume of 10 pounds of water...

What is an atom smasher?

As of 2014, the largest particle accelerator in the world is the Large Hadron Collider in Bern, Switzerland. The LHC went active in 2008, as part of the CERN accelerator complex, and consists of a 27-kilometer ring of supercooled magnets that act as superconductors. The bulk of the LHC apparatus is an elaborate cooling system that maintains these magnets an operating temperature of -271.3 degrees Celsius. This temperature, which is colder than the average temperature of outer space, is necessary to allow the free flow of current through the magnets and dramatically boost their power.\nInside t..

What does the cerebral cortex do?

The cerebral cortex, which is divided into three functional areas, is involved in receiving sensory information such as visual, auditory and tactile data. It sends this information to other parts of the brain for processing. The cerebral cortex also has regions of association. These regions allow the brain to function at a higher level and are involved with memory, language, creativity, emotion, attention, judgement and abstraction.

How does chemistry relate to biology?

The Oxford Dictionary defines "life" as having the capacity for growth, reproduction, functional activity and continuous change preceding death. None of these things can occur without chemical reactions. All of these traits require the metabolism and synthesis of outside materials and the consumption and release of chemically stored energy sources. Even seemingly physical processes, such as muscle movement, require the chemical release of energy, following processes mandated by an organism's DNA code. DNA is itself a coded strand of chemicals that implements its instructions by chemical p..

Is gasoline a pure substance or a mixture?

Although gasoline is a refined liquid product made up of a mixture of many hydrocarbons, the composition of gasoline varies and depends on different factors, such as the specific crude oil used and the refinery process. Likewise, to improve its performance, manufacturers and distributors often include additives and other agents with commercial gasoline. For these reasons, there are many unique blends or mixture components used to produce gasoline.\nGasoline is the typical fuel utilized for the internal combustion engines of cars.

What is calcium bicarbonate?

All water molecules that have contact with the atmosphere absorb some carbon dioxide. Some water, such as the water found in streams, also encounter s rocks and other sediments. The water molecules of this water gain metal ions such as magnesium and calcium, which can react with the carbon dioxide and water. As a result, compounds such as calcium bicarbonate form and create hard water.

Where does upwelling occur?

Although upwelling also occurs in the middle of the ocean, much of the upwelling research has focused on coastal regions. Coastal upwelling is associated with winds blowing parallel to the shore. These winds cause upwelling currents in which deep water flows toward the shore, rises and flows back out to sea along the surface. Equatorial upwelling is associated with the Intertropical Convergence Zone, which results in a large band of higher phytoplankton concentration in the Pacific Ocean along the equator.

What is the bulk density of coal?

The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter. It is a mature coal and is very hard and shiny. Bituminous coal has a bulk density of 42 to 57 pounds per cubic feet, or 673 to 913 kilograms per cubic meter. It ignites easily and burns long with a relatively long flame. Lignite coal has a bulk density of 40 to 54 pounds per cubic feet, or 641 to 865 kilograms per cubic meter. It is considered to be immature coal, and it is somewhat light in color and rema..
