You may have seen ads for perfumes promising to help attract a date using pheromones or you may have used insect pheromones in your garden to attract and control pests. Bacteria, ciliated protozoa, plants, insects, and non-human vertebrates rely on pheromones to raise alarms, attract mates, lure prey, mark food and territory, and otherwise affect the behavior of other members of their species.
Salmon farming, which involves raising salmon in containers placed underwater near the shore, began in Norway about 50 years ago and has since caught on in the United States, Ireland, Canada, Chile and the United Kingdom.

Using a superlative form of an adjective takes the basic sense of the adjective to the extreme, so the superlative of "basic" would be "most basic." Identifying Superlatives Latin superlative adjectives are usually easy to identify. Most contain -issim- (e.g., suavissimus, -a, -um 'most charming'). If they don't have -issim-, they will likely have -llim- (d ifficillimus, -a, -u 'most difficult') or -rrim- ( celerrimus, -a, -um 'swiftest') in them.
Sororities and fraternities are an integral part of non-academic life on many university campuses. Since the founding of Phi Beta Kappa, the first fraternity, at William & Mary College in 1776, these student clubs or social communities have been named after letters of the Greek alphabet-and the system of fraternities and sororities as a whole has been dubbed, simply, Greek life.
Monopsony is a market structure in which there is only one buyer of a good or service. If there is only one customer for a certain good, that customer has monopsony power in the market for that good.

In 1913, English metallurgist Harry Brearley, working on a project to improve rifle barrels, accidentally discovered that adding chromium to low carbon steel gives it stain resistant. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium.
Time dilation is the phenomenon where two objects moving relative to each other (or even just a different intensity of gravitational field from each other) experience different rates of time flow. Relative Velocity Time Dilation The time dilation seen due to relative velocity stems from special relativity.

He made two trips to Florida: one in 1513 and the second in 1521. It was on this latter expedition that he was wounded by natives and died shortly thereafter.
There are many times when you need to split a string into an array of strings by using a character as a separator. For example, a CSV ("comma" separated) file might have a line like "Zarko;Gajic;;DelphiGuide" and you want this line to be parsed into 4 lines (strings) "Zarko", "Gajic", "" (empty string) and "DelphiGuide" using the semi-colon character ";" as a delimiter.
In 1944, Lt. Hiroo Onoda was sent by the Japanese army to the remote Philippine island of Lubang. His mission was to conduct guerrilla warfare during World War II. Unfortunately, he was never officially told the war had ended; so for 29 years, Onoda continued to live in the jungle, ready for when his country would again need his services and information.
It's one of the iconic images of evolution: 400 or so million years ago, way back in the prehistoric mists of geologic time, a brave fish crawls laboriously out of the water and onto land, representing the first wave of a vertebrate invasion that leads to dinosaurs, mammals, and human beings. Logically speaking, of course, we don't owe any more thanks to the first tetrapod (Greek for "four feet") than we do to the first bacterium or the first sponge, but something about this plucky critter still tugs at our heartstrings.

If culture is understood by sociologists as composed of the commonly understood symbols, language, values, beliefs, and norms of a society, then a consumerist culture is one in which all of those things are shaped by consumerism-an attribute of a society of consumers. According to sociologist Zygmunt Bauman, a consumerist culture values transience and mobility rather than duration and stability, and the newness of things and reinvention of oneself over endurance.
Concatenation in the Java programming language is the operation of joining two strings together. You can join strings using either the addition ( + ) operator or the String's concat() method.

Drum memory, an early form of computer memory, used the drum as a working part, with data loaded to the drum. The drum was a metal cylinder coated with a recordable ferromagnetic material. The drum also had a row of read-write heads that wrote and then read the recorded data. Magnetic core memory (ferrite-core memory) is another early form of computer memory.
Shortly after the Trojan War, Greece fell into a dark age about which we know little. With the return of literacy at the beginning of the 8th century, BCE came the end of the dark age and the start of what is called the Archaic Age. In addition to the literary work of the composer of the Iliad and the Odyssey (known as Homer, whether or not he actually wrote one or both), there were stories of creation told by Hesiod.
Your first task in writing a descriptive essay is to choose a topic that has many interesting parts or qualities to talk about.
