What can be the "weak point" in a person?

In "The Art of War" by Sun Tzu, much is talked about of finding and exploiting an opponent's weaknesses to achieve victory. This principle equally applies outside of warfare and is useful in any conflict or interaction.\nPhysical weakness is a common trait people focus on. This could be a lack of physical strength, a bad knee or a debilitating disease. A person can also have a less visible physical weakness, such as an addiction to gambling.\nThere are social weaknesses as well. A person may have much of their self-worth wrapped up in their monetary worth or social standing, and this pers..

How does hydrogen peroxide kill bacteria?

The destructive oxygen in hydrogen peroxide is known as a free radical. The peroxide group, which is composed of two oxygen ions, reacts with bacterial cell walls and other cells' structures. Each oxygen atom has an unpaired electron, which is highly unstable and makes it extremely reactive.\nWhile hydrogen peroxide is a common disinfectant due to its bacteria-killing properties, it is dangerous to human cells as well as bacteria. It damages the surrounding tissue if it is left on a wound for too long. At higher concentrations, it is corrosive. The body has some defenses against this acti..

Where does arsenic come from?

Because of the location of arsenic in geological formations, the contamination of ground water and drinking water is often a concern. This is especially common in non-urban areas that contain wells for drinking. Arsenic is poisonous to any multi-cellular organism, including humans.\nBecause of its damaging properties, it is often used in pesticides and poisons to exterminate unwanted pests. Arsenic has other uses, such as being an ingredient in car batteries and the strengthening of copper alloys.\nArsenic is the 53rd most abundant material found within the Earth's crust, and common soil ..

How do you use dye to detect a pool leak?

When pool water needs replacement often, it can be a sign of leaks in the pool. It can be difficult to pinpoint the exact location of leaks, but a leak detection dye tester can find these leaks, which must then be repaired. Dye testing products are syringes that contain dye and also have an attached long needle/nozzle for the accurate placement of dye near leaks. These dye testers may be utilized near hydrostatic valves, fittings, cracks or tears in liners.Prepare the pool for the dye testEnsure that the pool is filled to its normal capacity level and turn off the pump. Make sure that the pool..

What is a petroleum landman?

Obtaining the mineral rights to a piece of land usually involves research and negotiation. The property in question may have many owners. The landman represents the petroleum company. His responsibilities include researching public and private records, reviewing title status, and negotiating with all involved parties. Early in his career, former United States president George W. Bush worked as a landman for a petroleum company.

What are some plants that grow on the forest floor?

The forest floor is covered in a layer of decomposition known as detritus. This fertile ground cover is important for nourishing the plants that are capable of surviving in the dark under layer of a forest. As animals decompose along the forest floor, nutrients seep into the soil and help feed plants that would otherwise be malnourished.\nTrees such as the mangrove are capable of surviving on the forest floor because of a unique root system that has adapted to the wet climate. The roots grow up the base of the tree to help provide the strength to keep the tree upright when the forest floor is ..

What were two types of organisms in the kingdom Monera?

One functional classification system divides organisms by their cell types rather than their genomes. Bacteria belong to the prokaryotes, distinguished by the lack of a nucleus and membrane-enclosed organelles in their cells. Most prokaryotes are single-celled organisms only visible under a microscope. Eukaryotes include protists, fungi, plants and animals. Archaea are prokaryotes that share some characteristics with eukaryotes, including similar genes.

Why is styrofoam a good insulator?

Three different processes allow heat energy to flow: radiation, convection and conduction. Of these, conduction and convection are the two processes relevant to the use of Styrofoam. Conduction involves the flow of heat energy from a hotter object to a colder one. For example, a person picking up an ice cube notices that the ice cube melts in his hand as heat conducts from his hand to the cube. Convection involves a series of currents that emerge when a gas or liquid flows from a warmer place to a cooler one, or vice versa.\nStyrofoam is a poor conductor, and the air pockets trapped inside the..

What does BC and AD mean?

B.C. and A.D. are used to mark years prior to or after the epochal, or origin event of the era, namely the birth of Jesus of Nazareth. The system was designed in 525 by Dionysus Exiguus as a replacement for the Diocletian designation system and became popular throughout Europe from the 11th through 14th centuries.\nNeutral alternatives to the Christian-centric designations include the abbreviations B.C.E. and C.E., which stand for "Before Common Era" and "Common Era."

How do the summer and winter monsoons differ?

The duration and conditions associated with both monsoons depend largely on the conditions over the Indian Ocean, where they form and the presence or absence of other atmospheric conditions. Generally, the end of winter brings warm and humid air from the southwestern part of the Indian Ocean; this air makes its way towards land, eventually settling over Southeast Asia.\n\nThe summer monsoon brings rain every day. Excessive atmospheric moisture and unusually warm air can create torrential, relentless rains that may devastate crop fields and wreak havoc in riverside communities and cities.\n\nWi..
