What is the relationship between anatomy and physiology?

Anatomical study is achieved through simple inspection such as visual observation, palpation, auscultation and percussion. Through palpation, an object in or on the body is felt to determine size, shape, firmness or location. Through auscultation, the internal sounds of the body are heard. By percussion, an examiner can feel abnormal resistance and listen to emitted sounds by tapping on the body. A deeper anatomical understanding is achieved through cadaver dissection or medical imaging. As explained by the Encyclopedia Britannica, technological advances such as the microscope allow for advanc..

What is the chemical formula for beryllium iodide?

Beryllium iodide has the appearance of colorless, needle-like crystals. It can be formed through beryllium metal reacting with elemental iodine at temperatures from 500 to 700 degrees Celsius. It can also be created with beryllium carbide reacting to hydrogen iodide in the gas phase. Its molar mass is 262.821 grams per mole. It melts at 480 degrees Celsius and boils at 590 degrees Celsius.

What is the difference between a jungle and a rain forest?

Since rain forests have canopies that limit the amount of light, there are relatively few plants on the forest floor. If the rain forest canopy is destroyed, more light reaches the forest floor, causing increased plant growth. Some plants that grow include vines, shrubs and other plants that require significant light to grow. The increased plant growth causes the rain forest to turn into a jungle.

Where do you find magnets in a house?

Electromagnetic motors are found in refrigerators, small kitchen appliances, garbage disposals, furnace fans, oven and ceiling fans, electric clocks and timers, CD and DVD players, printers, washers and dryers, vacuum cleaners, hair dryers, electric toothbrushes and computers.\nOut in the garage, electromagnetic motors are in drills, power saws, edgers, leaf blowers, power washers, garage door openers, and electric lawn mowers.\nPushing a doorbell button activates a magnetic solenoid, and telephone speakers convert electrical waves into sound using electromagnetic coils interacting with perman..

What can be done to prevent acid rain?

Lowering energy consumption on a daily basis is the best way to prevent the formation of acid rain. For instance, homeowners can turn off appliances and electronics when they are not in use. Buying energy-efficient appliances is also helpful. Use air conditioning and heating units only when necessary, and turn down the heat to conserve more energy.\nUsing alternative energy sources in the form of solar or wind decreases the amount of fossil fuels that are burned into the atmosphere. For instance, solar-based heating systems are available, including energy-efficient vehicles. Reducing car traff..

How do tsunamis start?

Most often, tsunamis start from underwater earthquakes that happen along tectonic plate lines. Earthquakes that shift one side up or down significantly cause a sudden change in where that volume of water is located, which in turn creates a large wave. The wave then continues until it reaches land. Other underwater causes include underwater landslides or landshifts, which are often caused by earthquakes. These underwater causes are usually the most dangerous.\nCauses that affect the surface of the ocean are less deadly, and the resulting waves tend to lessen in strength as they emanate from the..

What are examples of combustible materials?

Other combustible liquids include acetic acid, camphor oil, cyclohexane, varsol, methyl lactate, phenol, carbolic acid and aniline. Liquids that also have flash points above 100 degrees Fahrenheit are benzaldehyde, ethylene glycol, phenyl ether and stearic acid.\nFlammable materials also undergo combustion, but OSHA does not classify them as combustible materials. Liquids such as gasoline, ethanol, turpentine, potassium sulfide, napthalene and sulfur are flammable materials that give off vapors below 100 degrees Fahrenheit.\nCombustion is the chemical process of burning hydrocarbons in the pre..

What happens to pyruvate under anaerobic conditions?

In humans, pyruvate, also known as pyruvic acid, is produced during glycolysis. Glycolysis is the process of breaking up glucose for energy that cells can use. Pyruvate can then go into the mitochondria and enter the citric acid cycle if oxygen is available. If this aerobic pathway is not possible, pyruvate undergoes fermentation with the help of two NADH molecules, which produces lactic acid. This acid can then be transported from the cell and stored in the liver for later use.

What is the electron configuration for gallium?

A neutral atom of gallium has 31 electrons. The negative charge of each electron cancels out the positive charges of the 31 protons, giving a neutral gallium atom a net charge of zero.\n\nGallium's electron configuration shows how these 31 electrons are arranged. One atom of gallium has two electrons in the first energy level, eight in the second energy level, 18 in the third energy level and three in the fourth energy level.\n\nThe 4s2 and 4p1 parts of the configuration show how many valence electrons are in a gallium atom. The outer shell has a total of three electrons -- two in the s o..

What planet has the highest amount of gravity?

Jupiter is so large that all of the other planets in the solar system are able to fit inside. Its surface gravity is 27 yards squared. This causes objects to weigh more than twice as much as they would weigh on Earth. Jupiter has 62 moons in part due to its high amount of gravity. Its gravity also causes damage to passing asteroids and space matter.
