Car Albums in 1978’s

The band's hits dominated the charts for over nine years; their most victorious albums were 1978's The Cars, which featured hit "Just What I Needed," and 1984's Heartbeat City, which included four Top 20 singles: "Magic," "Drive," "Hello Again," and "You Might Think," which also won the MTV Video of the Year Award . "Drive" gained fastidious notability when it was used in a video of the Ethiopian food shortage prepared by the Canadian Broadcasting Corporation and introduced by David Bowie at the 1985 Live Aid concert at Wembley Stadium.

After the consequential period of superstardom and another hit single, the Cars released their last album Door to Door in 1987, but it failed to approach the success of their previous albums. The Cars announced the group's disintegrate in February 1988. In the late 1990s, rumors circulated of a Cars reunion, but Orr's death of pancreatic cancer on October 3, 2000 position an end to them.

Starting in late 2004, The Cars punch song "Just What I Needed" was played in Circuit City television ads.

CARS

The Cars were an American new wave band, one of the most admired to emerge out of the early punk scene in the late 1970s. They hailed from Boston, Massachusetts and were signed to Elektra report in 1977.

The band's members were Ric Ocasek (born Richard Otcasek), the band's principal songwriter, rhythm guitarist, and part-time lead singer; Benjamin Orr (born Benjamin Orzechowski), bassist and recreational lead singer; Elliot Easton, lead guitar and backing vocals; David Robinson, drums and backing vocals; and Greg Hawkes, keyboards, saxophone, guitar, and backing vocals. The nucleus of the assemblage was composed of guitarists Ocasek and Orr.

The Cars productively bridged the gap between the guitar-oriented rock of the 1970s and the synth-oriented pop of the early 1980s. While most of the singles included an Elliot Easton guitar solo, The Cars' sound was distinct much more by Greg Hawkes' synthesizers and the huge harmonies of Easton, Robinson, and Hawkes behind Orr's and Ocasek's lead vocals.

Collective and non-human intelligence

Some thinkers have explored the idea of combined intelligence, arising from the coordination of many people.

A battleship, for instance, cannot be operated by a single person's knowledge, actions and intelligence, it takes a corresponding and interacting crew.

Similarly, the interesting behaviors of a bee colony are not exhibited in the intelligence and actions of any lone bee, but rather manifested in the behavior of the hive.

These ideas are explored as a foundation for human thought, with applications for artificial intelligence (AI), by MIT AI pioneers Norbert Wiener and Marvin Minsky. Artificial intelligence (AI) has emerged from Computer science as a specialty which seeks to make computers do something in increasingly intelligent ways, and provides insights into human thought processes.

When considering animal intelligence, a more common definition of intelligence might be applied: the "ability to adapt effectively to the environment, either by making a change in oneself or by changing the environment or finding a new one" (Encyclopædia Britannica).

Many people have also speculated about the opportunity of extraterrestrial intelligence.

Intelligence, IQ, and g

Intelligence, IQ, and g are very different. Intelligence is the term used in ordinary discourse to refer to cognitive ability.

However, it is usually regarded as too imprecise to be useful for a scientific treatment of the subject. The intelligence quotient (IQ) is an index calculated from the scores on analysis items judged by experts to encompass the abilities coverd by the term intelligence.

IQ measures a multidimensional magnitude: it is an amalgam of dissimilar kinds of abilities, the proportions of which may differ between IQ tests.

The dimensionality of IQ scores can be premeditated by factor analysis, which reveals a single dominant factor underlying the scores on all IQ tests.

This factor, which is a hypothetical construct, is called g. Variation in g corresponds very much to the intuitive notion of intelligence, and thus g is sometimes called general cognitive ability or general intelligence.

Artificial intelligence

Artificial intelligence (also known as machine intelligence and often abbreviated as AI) is intelligence exhibited by any contrived (i.e. artificial) system. The term is often applied to common purpose computers and also in the field of scientific investigation into the theory and practical application of AI. "AI" the name is often used in works of science fiction to refer to that which exhibits artificial intelligence as well, as in "the AI" referring to a singular discrete or distributed mechanism. Modern AI research is disturbed with producing useful machines to automate human tasks requiring intelligent behavior. Examples include: scheduling resources such as military units, answering questions about products for customers, thoughtful and transcribing speech, and recognizing faces in CCTV cameras.

As such, it has become an engineering control, focused on providing solutions to practical problems. AI methods were used to plan units in the first Gulf War, and the costs saved by this efficiency have repaid the US government's entire investment in AI research since the 1950s. AI systems are now in routine use in many businesses, hospitals and military units approximately the world, as well as being built into many common home computer software applications and video games. (See Raj Reddy's AAAI paper for a complete review of real-world AI systems in deployment today.) AI methods are often employed in cognitive science research, which openly tries to model subsystems of human cognition.

camera

A camera is a mechanism used to take pictures, either singly or in sequence, with or without sound, such as with video cameras. The name is derivative from camera obscura, Latin for "dark chamber", an early mechanism for projecting images in which an entire room functioned much as the interior workings of a modern photographic camera, except there was no way at this time to record the image short of manually tracing it. Cameras may work with the visual range or other portions of the electromagnetic spectrum.

Every camera consists of some type of enclosed chamber, with an opening or space at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. This distance of the aperture is often controlled by an diaphragm mechanism, but some cameras have a fixed-size aperture.

Axiomatic geometry

What is geometry?

Recorded growth of geometry spans more than two millennia. It is hardly astonishing that perceptions of what constituted geometry evolved throughout the ages. The geometric paradigms offered below should be viewed as 'Pictures at an exhibition' of a sort: they do not weaken the subject of geometry but rather reflect some of its defining themes.

Practical geometry:

There is small doubt that geometry originated as a practical science, concerned with surveying, measurements, areas, and volumes. Among the distinguished accomplishments one finds formulas for lengths, areas and volumes, such as Pythagorean theorem, circumference and area of a circle, area of a triangle, volume of a cylinder, sphere, and a pyramid. Development of astronomy led to appearance of trigonometry and spherical trigonometry, together with the attendant computational techniques.

Geometry

Geometryis a part of mathematics disturbed with questions of size, shape, and relative position of figures and with properties of space. Geometry is one of the important oldest sciences. Initially a body of sensible knowledge concerning lengths, areas, and volumes, in the third century B.C. geometry was put into an axiomatic form by Euclid, whose treatment set a standard for many centuries to follow. Astronomy served as an important source of geometric troubles during the next one and a half millennia.

Introduction of coordinates by Descartes and the concurrent improvement of algebra marked a new stage for geometry, since geometric figures, such as plane curves, could now be represented analytically. This played a key role in the appearance of calculus in the seventeenth century. Furthermore, the theory of outlook showed that there is more to geometry than just the metric properties of figures.

Rectangle

In geometry, a rectangle is defined as a four-sided figure where all four of its angles are right angles.

From this definition, it follows that a rectangle has two pairs of parallel sides; that is, a rectangle is a quadrilateral. A square is a exceptional kind of rectangle where all four sides have equal length; that is, a square is both a rectangle and a rhombus. A rectangle that is not a square is colloquially known as an four-sided figure.

Normally, of the two opposite pairs of sides in a rectangle, the duration of the longer side is called the length of the rectangle, and the duration of the shorter side is called the width. (Exception: For rectangular steel sheets, the rolling direction is called length, even if it is the shorter side.)

The area of a rectangle is the multiplication of its length and its width; in symbols, A = lw. For example, the area of a rectangle with a length of 6 and a width of 5 would be 30, because 6*5=30

In a rectangle the diagonals cross each others at their respective midpoints, under the same argument as for parallelograms. And unlike general parallelograms the two diagonals of a rectangle have the same length, the length of the diagonal can be found using the Pythagorean theorem.

In calculus, the Riemann fundamental can be thought of as a limit of sums of the areas of arbitrarily thin rectangles.

Sports

Perfect is a physical phenomenon known to athletes? When a person exercise at a certain level for a certain period over a certain number of weeks, their body will raise its metabolism to a higher level - it will continue at this level as long as a certain amount of exercise is performed each couple of days. This result was discovered by Dr. Kenneth H. Cooper for the United States Air Force in the late 1960s. Dr. Cooper coined the term "Training Effect" for this.

The measured effects were that muscles of respiration were strengthened, the heart was strengthened, blood pressure was infrequently lowered and the total amount of blood and number of red blood cells increased, making the blood a more competent carrier of oxygen. VO2 Max was amplified.

The exercise necessary can be talented by any aerobic exercise in a wide diversity of schedules - Dr. Cooper found it best to award "points" for each amount of exercise and require 30 points a week to preserve the Training Effect.

As it would be foolish for someone unconditioned to challenge 30 points in their first week, Dr. Cooper instead recommends a "12-minute test" followed by adherence to the appropriate starting-up schedule in his book. As always, he recommends that a physical exam should lead any exercise program.

Abstract art

Abstract art is now usually understood to mean art that does not depict objects in the natural world, but instead uses color and form in a non-representational way. In the very early 20th century, the term was more often used to describe art, such as Cubist and Futurist art, which depicts real forms in a simplified or rather reduced way—keeping only an allusion of the original natural subject. Such paintings were often claimed to capture amazing of the depicted objects' immutable intrinsic qualities rather than its external appearance. The more precise terms, "non-figurative art," "non-objective art," and "non-representational art" avoid any possible ambiguity.

Salwar kameez

Salwar kameez is also spelled shalwar kameez and shalwar qamiz is a traditional dress worn by both women and men in Pakistan, India, Bangladesh, and Afghanistan. It is now and then known as Punjabi suit due to its popularity in the Punjab region and the Pathani suit, due to the fact that the Pathans of Kabul introduce the dress to the rest of South Asia.

It is loose pajama like trousers the legs are wide at the top and narrow at the bottom,
The kameez is a long shirt or tunic. The part seams known as the chaak are left open below the waist-line, which gives the wearer greater freedom of movement. In Afghanistan and Pakistan, it is the favored garment of both sexes. In Bangladesh and India, it is most normally a woman's garment. Though the majority of Indian women wear traditional clothing, the men in India can be found in more conservative western clothing. Shalwar kameez is the traditional dress worn by a variety of peoples of south-central Asia. In India and Pakistan it is a particularly popular style of dress. Shalwar or Salwar is a short loose or parallel trouser.

Economic and social history

Dutch economic strategy for the colony throughout the eighteenth and nineteenth centuries can be clear along three overlapping periods: the Cultivation System, the Liberal Period, and the Ethical Period. Throughout these periods, and until Indonesian independence, the utilization of Indonesia's wealth contributes to the industrialization of the Netherlands. Large expanses of Java, for example, became plantations cultivated by Javanese peasants, together by Chinese intermediaries, and sold on overseas markets by European merchants. Before World War II, the majority of the world's supply of quinine and pepper, over a third of its rubber, a quarter of its coconut products and a fifth of is tea, sugar, coffee, and oil. Indonesia complete the Netherlands was one of the world's most important colonial powers.

Despite increasing returns from the Dutch system of land tax, Dutch finances had been severely exaggerated by the cost of the Java and Padre Wars. The Dutch loss of Belgium in 1830 brought the Netherlands to the brink of bankruptcy, and a concerted Dutch utilization of Indonesian resources commenced. In 1830, a new governor general, Johannes van den Bosch, was selected to make the Dutch East Indies to pay their way. An agricultural plan of government-controlled forced cultivation was introduced to Java. Known as the Cultivation System (Dutch: cultuurstelsel); much of Java became a Dutch plantation, making it a profitable, self-sufficient colony and saving the Netherlands from bankruptcy. The Cultivation System, however, brought much economic hardship to Javanese peasants, who suffer famine and epidemics in the 1840s.

Health care

Health care, or healthcare, is the prevention, treatment, and management of illness and the defense of mental and physical well being through the services available by the medical, nursing, and allied health professions. According to the World Health Organization, health care embrace all the goods and services measured to promote health, as well as preventive, curative and palliative interventions, whether going to be individuals or to populations. The organized provision of such services may make up a health care system. This can include an exact governmental organization such as, in the UK, the National Health Service or cooperation across the National Health Service and Social Services as in Shared Care. Before the term "health care" become popular, English-speakers referred to medicine or to the health sector and spoke of the behavior and prevention of illness and disease.

Vegetable

Vegetable is a cookery term which usually refers to an edible part of a plant. The definition is traditional rather than scientific and is somewhat random and subjective. All parts of herbaceous plants eaten as food by humans, whole or in part, are in general considered vegetables. Mushrooms, though belong to the biological kingdom fungi, and are also commonly considered vegetables. In common, vegetables are consideration of as being savory, and not sweet, although there are many exceptions. Nuts, grains, herbs, spices and culinary fruits are usually not exact vegetables.

Denim

Denim, in American usage since the late eighteenth century, shows a rough cotton twill textile, in which the weft passes under two (twi- "double") or more warp fibers, producing the memorable diagonal ribbing specialized on the reverse of the fabric, which distinguishes denim from cotton duck. Denim was conventionally colored blue with indigo dye to make blue "jeans," though "jean" then denoted a different, lighter cotton textile; the up to date use of jean comes from the French word for Genoa, Italy (Genes), from which the initial denim trousers were made.

Fuel and propulsion technologies

Most automobiles in use nowadays are propelled by gasoline is also known as petrol or diesel internal combustion engines, which are known to reason for air pollution and are also blamed for contributing to climate change and global warm. Increasing costs of oil-based fuels and tapering environmental laws and restrictions on greenhouse gas emissions are propelling work on substitute power systems for automobiles. Efforts to get better or replace these technologies include hybrid vehicles, electric vehicles and hydrogen vehicles.

Essentials of healthy life-cleanliness a brief review


Health is wealth so preserve it. Life is short so use it in the right way. Cleanliness merely fits with the apt meaning of being free from dirt, dust, germs and bad smells. A recent shift has now taken place to recognize that 'germs' may play a major role in our immune systems. So experts say washing hands frequently, especially when in an environment of many people with infections and diseases. Washing is one of the best ways to achieve cleanliness. Have a brief overlook on the following issue to be aware of how to keep one self clean.
A step way process regarding cleanliness of hands is given below:

• Use warm water
• But avoid scorching your hands.
• Use anti-bacterial soap or hand wash.
• Wash between fingers and use paper towels to wipe off.
Washing of hands has to be followed
• Before eating
• After eating
• After using the toilet
• After playing outdoor games
• After attending to a sick person
• After blowing nose, coughing, or sneezing; and after handling pets.
The proverb "Cleanliness is next to Godliness," a common phrase that describes humanity's high opinion of being clean. Purposes of cleanliness include health, beauty and to avoid the spreading of germs .If your hands have any kind of skin cut or infection, wash hands with an anti bacterial soap.

DVD

DVD ("Digital Versatile Disc" or "Digital Video Disc") is an admired optical disc storage space media format that can be used for data storage, like movies with high video and sound quality. DVDs be similar to Compact Discs in that they have the precise appearance (i.e. diameter: 120 mm or 4.72 in, occasionally 80 mm or 3.15 in.) and both are optical storage media so similar that a DVD reader or writer can usually read CDs, but DVDs are encoded in a dissimilar format of much greater density, allowing a data storage capability 8 times greater (single-layer, single-sided).

All read-only DVD discs, regardless of type, are DVD-ROM discs. This includes replicated (factory pressed), recorded (burned), video, audio, and data DVDs. A DVD with properly formatted and structured video content is a DVD-Video disc. Everything else, (including other types of DVD discs with video content) is known as a DVD-Data disc. Consumers use the term "DVD-ROM" to refer to pressed data discs only, but that is wrong usage; moreover, the term DVD is also applied basically in describing newer video disc formats, Blu-ray Disc and HD DVD.

Fertilisation


Fertilisation or fertilization also known as conception, fecundation and syngamy, is fusion of gametes to form a new organism of the same variety. In animals, the process involves a sperm fuse with an ovum, which finally leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in interior fertilisation, or outside in the case of external fertilisation.

The entire process of development of new persons is called procreation, the act of species reproduction.

Aggregate fruit

An aggregate fruit, or etaerio, develops from a flower with many simple pistils. An example is the raspberry, whose simple fruits are termed drupelets since each is like a small drupe attached to the receptacle. In some bramble fruits such as blackberry the receptacle is stretched out and part of the ripe fruit, making the blackberry an aggregate accessory fruit. The strawberry is also an aggregate- accessory fruits, only one in which the seeds are controlled in achenes. In all these examples, the fruit develops from a single flower with many pistils.

Waka

In the Maori language, waka are Maori watercraft, usually canoes. Similar craft are encounter in Polynesia, with connected names such as vaka. Waka range is from small, lightweight canoes, such as waka tiwai used for fishing individuals, during very large waka taua, manned by up to eighty paddlers and up to fourty mtrs in length, large double-hulled canoes for oceanic voyaging.

Many waka are single-hulled vessels locate from hollowed tree trunks. Small waka consist of an only piece as large waka typically consist of some pieces jointed and lashed together. Some waka, mainly in the Chatham Islands, were not usual canoes but were constructed from raupo stalks. Ocean waka, Paddled could be in any size, but were usually propelled by sail. Waka taua are paddled to put across their mana.

Small efficient waka are commonly plain and simple. Superior canoes waka taua in testing are extremely carved. Waka taua are no longer used in fighting but frequently for official purposes.

Punt

A punt is a flat-bottomed boat with a square-cut bow, planned for use in small rivers or other shallow water. Punting refers to boating in a punt; the punter normally propels the punt by pushing beside the river bed with a pole.
Punts were initially built as cargo boats or platforms for fowling and angling but in modern times their use is almost wholly confined to pleasure trips on the rivers in the university towns of Oxford and Cambridge in England and races at a few summer regattas on the Thames.
A customary river punt differs from many other types of wooden boat in that it has no keel, stem or sternpost. In its place it is built rather like a ladder with the main structure being two side panels connected by a series of 4 in (10 cm) cross planks, known as "treads", spaced about 1 foot (30 cm) apart.
The first punts are traditionally linked with the River Thames in England and were built as small cargo boats or platforms for fishermen. Pleasure punts — particularly built for recreation — became popular on the Thames between 1840 and 1860. Some other boats have a similar shape to a traditional punt — for example the Optimist training dinghy or the air boats used in the Everglades — but they are normally built with a box construction instead of the open ladder-like design of a traditional Thames pleasure punt.

Longboat

His longboat should not be confused with a Long ship; or with a narrow boat. In the days of sailing ships, a vessel would take a number of boats for various uses. One would be a longboat, an open, mainly rowing boat with eight or ten oarsmen, two per spoil. In other words the longboat was double banked: its rowing benches were planned to accommodate two men. Unlike the vessel or the cutter, the longboat would have quite fine lines aft to permit its use in steep waves such as surf or wind against tide where need be.
It had the double-banked understanding in common with the cutter. This was possible as it had a beam alike to a cutter's but broader than that of a gig, which was solitary banked. The longboat was frequently more seaworthy than the cutter which had a fuller stern for such load-carrying work as laying out an anchor and cable. In a seaway or surf therefore, the cutter was more flat to broaching to.

Jet-Ski

Jet-Ski is the brand name of personal watercraft (PWC) affected by Kawasaki Heavy Industries, Ltd... The name, however, has become a widespread trademark for any type of personal watercraft. Jet Ski (or Jet Ski) can also specially refer to versions of PWCs with pivoting handle poles known as "stand-ups".
Jet Ski becomes leading colloquial term for stand-ups because, in 1973, Kawasaki was in charge for a limited production of stand-up models as intended by the recognized inventor of jet skis, Clayton Jacobsen II. In 1976, Kawasaki then began mass manufacture of the JS400-A. JS400s came with 400 cc two-stroke engines and hulls based upon the previous incomplete release models. It became the harbinger of the achievement Jet-Skis would see in the market up through the 1990s.
In 1986 Kawasaki broadened the world of Jet Skis by introduce a two person representation with lean-in "sport" style handling and a 650cc engine, dubbed the X-2. Then in 1989, they innovate their first two traveler "sit-down" model, the Tandem Sport (TS) with a step-through seating area.
In 2003, Kawasaki famous the Jet Ski brand by release a special 30th anniversary edition of its current stand-up model, the SX-R, which has seen a renewal of interest in stand-up jet skiing. The X-2 has also been efficient, based on the SX-R platform and re-released in Japan. Kawasaki continues to produce three models of sit-downs, as well as many four-stroke models.

Hydroplane

A hydroplane (or hydro, or thunderbolt) is a very specific type of motorboat used completely for racing.
One of the unique things about these boats is that they only use the water they're on for propulsion and steering (not for flotation)—when going at full speed they are primarily detained aloft by a principle of fluid dynamics known as "planning", with only a tiny portion of their hull actually touching the water.
The basic hull design of most hydroplanes has remained comparatively unchanged since the 1950s: two sponsors in front, one on either side of the bow; behind the wide bow, is a narrower, mostly rectangular section housing the driver, engine, and steering equipment. The aft part of the vessel is supported, in the water, by the lower half of the propeller, which is intended to operate semi-submerged at all times. The goal is to stay as little of the boat in contact with the water as possible, as water is much denser than air, and so exerts more drag on the vehicle than air does. Basically the boat 'flies' over the surface of the water rather than actually traveling through it.

Fireboat

A fireboat is a paying attention watercraft, often similar to a tugboat, with pumps and nozzles planned for fighting shoreline and shipboard fires. They are mostly useful for fighting fires on docks and shore side warehouses as they can directly attack fires in the supporting underpinnings of these structures. They also have an countless supply of water available, pumping straight from the harbor and can be used to assist shore based firefighters when other water is in low supply or is unavailable, for example, due to earthquake breakage of water mains, as happened in San Francisco due to the 1989 Loma Pieta earthquake.
Modern fireboats are competent of pumping tens of thousands of gallons of water per minute. The most technically advanced of these is Fire Boat #2 of the Los Angeles Fire Department, the Warner Lawrence, with the capability to pump up to 38,000 US gallons per minute (2 m³/s) and up to 400 feet (120 m) in the air.

Spiral escalators

Spiral escalators acquire less horizontal space than straight escalators. However, in the early spiral designs were failures. For example, one spiral escalator constructed by Reno in combination with William Henry Aston and Scott Kietzman at London's Holloway Road Underground position in 1906 was dismantled almost right away and little of the mechanism survives. The Mitsubishi Electric Corporation has urbanized successful commercial designs and has contrived curved and spiral escalators since the 1980s.
Notable sets of spiral escalators are situated in the Westfield San Francisco Centre in San Francisco, California, and at Forum Shops at Caesars Palace in Las Vegas, Nevada. The Times Square shopping mall in Causeway Bay, Hong Kong, also features four curved escalators, as do Wheelock Place in Singapore.

Barge

A barge is a flat-bottomed boat, built mostly for river and canal transport of important goods. Most barges are not self-propelled and need to be moved by tugboats towing or towboats pushing them. Barges on inland waterways (towed by draft animals on an adjacent towpath) contended with the railway in the early industrial revolution but were out competed in the carriage of high value items owing to the higher speed, falling costs, and route elasticity of rail transport.
Barges are still used today for low value bulk items, as the cost of hauling goods by barge is very low. Barges are also used for very weighty or bulky items; a typical barge events 195 feet by 35 feet (59.4 meters by 10.6 meters), and can take up to 1500 tons of cargo.

Colossus of Rhodes

The Colossus of Rhodes was a giant statue of the god Helios, erected on the Greek island of Rhodes by Chares of Lindos, a pupil of Lysippos, between 292 BC and 280 BC. It was roughly the same size as the Statue of Liberty in New York, although it stood on a lower platform. It was one of the Seven Wonders of the World.

Alexander the Great died at an early age in 323 BC without having had time to put into place any plans for his succession. Fighting broke out among his generals, the Diadochi, with three of them eventually divides up much of his empire in the Mediterranean area. During the fighting Rhodes had sided with Ptolemy, and when Ptolemy eventually took control of Egypt, Rhodes and Ptolemaic Egypt formed an alliance which controlled much of the trade in the eastern Mediterranean. Another of Alexander's generals, Antigonus I Monophthalmus, was upset by this turn of events. In 305 BC he had his son Demetrius invade Rhodes with an army of 40,000. However, the city was well defended, and Demetrius had to start construction of a number of massive siege towers in order to gain access to the walls.

Identical twins

Identical twins occur when a single egg is fertilized to form one zygote which then divides into two separate embryos. This is not considered to be a hereditary trait, but rather an anomaly that occurs in birthing at a rate of about 1:150 births worldwide, regardless of ethnic background. The two embryos develop into fetuses sharing the same womb. When one egg is fertilized by one sperm cell, and then divides and separates, two identical cells will result. Depending on the stage at which the zygote divides, identical twins may share the same amnion, which can cause complications in pregnancy.

For example, the umbilical cords of monoamniotic twins can become entangled, reducing or interrupting the blood supply to the developing fetus. About 50% of mono-mono twins die from umbilical cord entanglement. Monochorionic twins, sharing one placenta, usually also share the placental blood supply. These twins may develop such that blood passes disproportionately from one twin to the other through connecting blood vessels within their shared placenta, leading to twin-to-twin transfusion syndrome.

Metamorphosis

Metamorphosis is a biological course by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure through cell growth and differentiation. Some insects, amphibians, molluscs, crustaceans, echinoderms and tunicates undertake metamorphosis, which is usually accompanied by a change of habitat or behavior. Scientific usage of the term is exclusive, and is not applied to common aspects of growth, including rapid growth spurts. References to “metamorphosis” in mammals are imprecise and only colloquial.

Metamorphosis usually proceeds in distinct stages, usually starting with larva or nymph, optionally passing through pupa, and ending as adult. The immature stages of a species that metamorphoses are regularly called larva. But in the complex metamorphosis of many insect species, only the first stage is called a larva and sometimes even that bears a different name; the distinction depends on the nature of the metamorphosis.
