What are some examples of organic molecules?

The carbohydrate group contains sugars, such as sucrose, and starches, such as cellulose. Sugars provide energy to living cells, while starches provide structure. The lipids group contains fats and oils, such as phospolipids and triglycerides. They provide energy and insulation and can act as signaling molecules. Proteins are large polymers that have many functions in living things, such as communication between cells, cell movement, structure and chemistry. Nucleic acids contain information needed by the cell. Deoxyribonucleic acid (DNA) carries the genetic code that creates living things. Ri..

Is wax flammable?

According to HowStuffWorks, wax is a petroleum product that is formed out of crude oil. Crude oil is the same natural substance from which gasoline and kerosene are produced. In addition to candles, wax is used as a fuel in manufactured fireplace logs and fire starters. In those applications, the wax is mixed with another flammable substance, such as sawdust, cotton fibers or newspaper. Because wax is very flammable, precautions are necessary when melting it in a home environment. Wax should be melted slowly in a double boiler to avoid fires.

What is the way to convet from centimeters to millimeters?

Centimeters and millimeters are commonly used because of their usefulness for marking more specific and smaller measurements commonly employed in design and engineering settings. This is even true in the United States, where measurements are still used under the U.S. Standard system, which is related to the imperial system. A centimeter is obviously not related to this system, where a centimeter is equal to .39370 of an inch.Centimeters can be very simply converted to millimeters, then. If someone has a quantity of 15 centimeters, they can convert this quantity to millimeters by dividing the q..

How is chromatography used to solve crime?

Chromatography is particularly useful in analyzing materials used in bombs and explosives. High-pressure liquid chromatography (HPLC) involves placing samples in a tube and extracting the materials using downward pressure. A machine is used to detect the speed at which the particles leave the tube. The measurements are used to identify the materials because they leave the tube at different speeds.\n\nChromatography is also useful to identify perpetrators of bank robberies. Money bundled in banks routinely contains a small dye bomb that projects bright red dye when triggered. Each dye has a uni..

What is the chemical formula for alcohol?

Ethanol, also known as ethyl alcohol, is a common alcohol produced by fermentation of sugars such as barley and grapes. Ethanol is found in alcoholic beverages such as beer and wine. The chemical formula for ethanol is CH3CH2OH; this formula can also be written as a condensed structural formula, C2H5OH. The molecular formula for ethanol is C2H6O. Other alcohols include methanol (CH3OH) and propan-1-ol (CH3CH2CH2OH).

How does a gas thermocouple work?

The thermocouple receives a small amount of heat from the pilot light, thereby creating about 20 to 30 millivolts or enough to keep the valve open for the pilot assembly. The thermocouple acts as a safety device which ensures that if the pilot light goes off, no gas will be released.A thermophile is a group of thermocouples inside a metal housing. It produces 900 millivolts of electricity to open an electromagnet inside the main burner when the main switch is turned on.

What is a jellylike liquid in the nucleus?

Nucleoplasm is made up primarily of water. Nucleotides, enzymes, and a variety of dissolved organic molecules and ions make up the remainder. The cellular chromosomes and nucleolus float freely in the nuceloplasm, which functionally provides a structured shape to the nuclear membrane. The fluid, soluble component of nucleoplasm is called the nuclear hyaloplasm. Plasmas such as nucleoplasm and cytoplasm generally exist in a liquid sol state or a jelly-like gel state.

How do you draw a Bohr model?

Find the number of electrons, protons and neutronsFrom the periodic table, find the element, and identify its atomic number and atomic weight. The atomic number of an element is shown on top of the symbol of the element, and the atomic weight is shown in the bottom. The atomic number of the element is equal to the number of electrons and protons in the element. The number of neutrons is attained by subtracting the atomic number from the atomic weight.\n\nFor example, carbon has an atomic number of 6 and an atomic weight of 12. So a carbon atom has six electrons, six protons, and six neutrons.D..

What is the purpose of a streak plate?

A streak plate is prepared with nutrients that are specifically chosen to support the growth of the desired organism. It may also contain chemicals that are toxic to other organisms. These chemicals will kill any organisms that might contaminate the organism you want to study. This combination should result in a plate of isolated colonies of a desired organism.\nAs well as isolating chosen organisms, streak plates may also be used to support more investigative study of a particular organism. The nutrients in a streak plate can be manipulated to study their effects on the organism, and by setti..

How do humans affect the nitrogen cycle?

The US National Library of Medicine reprinted a study by Scott Fields that concludes humans inject nitrogen compounds into the air in ever increasing quantities, causing serious impacts on biodiversity, human health, water quality, global warming and also the rate of population growth in developing nations.\nMost scientists agree that humans disrupt the nitrogen cycle by altering the amount of nitrogen stored in the biosphere. Burning fossil fuels results in a change in carbon storage, thus affecting the nitrogen cycle and other vital processes. It adds nitrogen to terrestrial ecosystems and l..
