3 is a number‚ numeral‚ and glyph. It is the natural number following 2 and preceding 4. In mathematics Three is approximately π when doing rapid engineering guesses or estimates. The same is true if one wants a rough-and-ready estimate of e‚ which is actually approximately 2.71828. Three is the first odd prime number‚ and the second smallest prime. It is both the first Fermat prime and the first Mersenne prime‚ the only number that is both‚ as well as the first lucky prime. However‚ it is

feedback in living organisms Negative feedback is a principle which is used by the body in order to return systems to its normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation‚ regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use negative

OVERVIEW INDEX NUMBERS compare figures which show changes in a given variable. The most common variables used in index numbers are price and quantity. By getting the difference of the index numbers‚ we are able to determine the relative or percent change in the price or quantity of a commodity between two periods of time or two localities. Among the more commonly used index numbers are the consumer price index‚ retail price index‚ wholesale price index‚ and the cost-of-living index. DEFINITION

Oxidation Number When elements combine to produce a compound‚ each element is assigned an “apparent” charge. This apparent charge‚ the charge an atom would have if both electrons in each bond were assigned to the more electronegative element‚ may be positive or negative. It is called the oxidation number or state of the element in the compound. Oxidation numbers are very useful in keeping track of what happens to electrons when various elements combine to form compounds. By remembering a few generalizations

A Little Too Many? Do you ever go out to eat some seafood and see the fish that is served? Have you ever thought about the abundance; how much fish there is? And have you ever thought about there being a shortage a fish; seems impossible‚ right? Because when we think of fish‚ we think of the millions or even billions of little or big swimming creatures in the huge ocean; how could there be a shortage? Overfishing is the answer. Overfishing is where we hunt fish faster than they can be replaced naturally;

ABSTRACT Reynolds number can be defined as a number of varieties of situations where a fluid is in relative with motion to a surface. This experiment is to observe the behavior of the flow of fluid either it is laminar or turbulent by calculating it’s Reynolds number and the characteristic of the flow. Other than that‚ the range for laminar and turbulent flow can be calculated and the theory that Reynolds number is dimensionless can be proven. The pump is opened to let the water flow. The dye

GMO’s are Genetically Modified Organisms. Many people argue that GMO’s are a problem and hurt the ecosystem‚ economy‚ and health of society. GMO’s are important because they help the food industry thrive‚ protect the crop to help it grow‚ and make the crop more efficient. First‚ GMO’s are important because they help the food industry thrive. This is because many GMO’s are manufactured and sold as a convenience to people‚ thus prompting them to buy the product. GMO’s greatly impact the food industry

A Human Is A Complex Organism Human beings are complex and special organisms as there is a complex organisation of cells in the human body. The organisation in the human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism.The same type of cells which carry out a specific function are organised into a tissue. For example‚ a group of nerve cells form a nerve tissue. They are organised to work together to perform specific functions as the result of cells in the human body

Only youth can steer nation back on its track “The Youth of a Nation are the trustees of posterity” said by Benjamin Disraeli. It is a fact that the stronger the youth‚ the more developed the nation is. The role of the youth in the nation-building occupies the central place. The countries which utilize their youth in as right direction are more developed. The energy and brightness of minds of youth act as torch-bearer for a nation. On the contrary‚ the countries which fail to realize the importance
