Context: 

Most sexually reproducing organisms are diploid, with paired chromosomes, but doubling of their chromosome number may occur due to errors in cytokinesis. This can occur early in development to produce an autopolyploid or partly autopolyploid organism, or during normal processes of cellular differentiation to produce some cell types that are polyploid (endopolyploidy), or during gamete formation. An allopolyploid plant may result from a hybridisation event between two different species. Both autopolyploid and allopolyploid plants can often reproduce normally, but may be unable to cross-breed successfully with the parent population because there is a mismatch in chromosome numbers. These plants that are reproductively isolated from the parent species but live within the same geographical area, may be sufficiently successful to form a new species. Some otherwise sterile plant polyploids can still reproduce vegetatively or by seed apomixis, forming clonal populations of identical individuals. Durum wheat is a fertile tetraploid allopolyploid, while bread wheat is a fertile hexaploid. The commercial banana is an example of a sterile, seedless triploid hybrid. Common dandelion is a triploid that produces viable seeds by apomictic seed.

Question: Are the plants produced by this error, able to reproduce?
Answer: often reproduce normally.

Some multiracial individuals feel marginalized by U.S. society. For example, when applying to schools or for a job, or when taking standardized tests, Americans are sometimes asked to check boxes corresponding to race or ethnicity. Typically, about five race choices are given, with the instruction to "check only one." While some surveys offer an "other" box, this choice groups together individuals of many different multiracial types (ex: European Americans/African-Americans are grouped with Asian/Native American Indians).

---

Question: What does the "other" box do?
Answer: groups together individuals of many different multiracial types.

In breeding circles, a male canine is referred to as a dog, while a female is called a bitch (Middle English bicche, from Old English bicce, ultimately from Old Norse bikkja). A group of offspring is a litter. The father of a litter is called the sire, and the mother is called the dam. Offspring are, in general, called pups or puppies, from French poupée, until they are about a year old. The process of birth is whelping, from the Old English word hwelp.

Question: What is the French word that "puppy" comes from?
Answer: poupée.

A large portion of music played on this format are either considered oldies or recurrent. It often deals with modern romantic and sexual relationships (and sometimes other adult themes such as work, raising children, and family) in a thoughtful and complex way. Soft AC, which has never minded keeping songs in high rotation literally for years in some cases, does not appear necessarily to be facing similar pressures to expand its format. Soft AC includes a larger amount of older music, especially classic R&B, soul, and 1960s and 1970s music, than hot AC.

Question: What radio station format is soft AC often contrasted with?
Answer: hot AC.

In Europe, there has been a general move away from religious observance and belief in Christian teachings and a move towards secularism. The Enlightenment is largely responsible for the spread of secularism. Several scholars have argued for a link between the rise of secularism and Protestantism, attributing it to the wide-ranging freedom in the Protestant countries. In North America, South America and Australia Christian religious observance is much higher than in Europe. United States remains particularly religious in comparison to other developed countries. South America, historically Roman Catholic, has experienced a large Evangelical and Pentecostal infusion in the 20th and 21st centuries.

The Enlightenment – known in French as the Siècle des Lumières, the Century of Enlightenment, and in German as the Aufklärung – was a philosophical movement which dominated the world of ideas in Europe in the 18th century. The Enlightenment included a range of ideas centered on reason as the primary source of authority and legitimacy, and came to advance ideals such as liberty, progress, tolerance, fraternity, constitutional government and ending the abuses of the church and state. In France, the central doctrines of the Lumières were individual liberty and religious tolerance, in opposition to the principle of absolute monarchy and the fixed dogmas of the Roman Catholic Church. The Enlightenment was marked by increasing empiricism, scientific rigor, and reductionism, along with increased questioning of religious orthodoxy.

Albert Einstein proposed that the laws of physics should be based on the principle of relativity. This principle holds that the rules of physics must be the same for all observers, regardless of the frame of reference that is used, and that light propagates at the same speed in all reference frames. This theory was motivated by Maxwell's equations, which show that electromagnetic waves propagate in a vacuum at the speed of light. However, Maxwell's equations give no indication of what this speed is relative to. Prior to Einstein, it was thought that this speed was relative to a fixed medium, called the luminiferous ether. In contrast, the theory of special relativity postulates that light propagates at the speed of light in all inertial frames, and examines the implications of this postulate.

Question: In all reference frames, how is the the speed of light?
Answer: the same.

The history of the Greek people is closely associated with the history of Greece, Cyprus, Constantinople, Asia Minor and the Black Sea. During the Ottoman rule of Greece, a number of Greek enclaves around the Mediterranean were cut off from the core, notably in Southern Italy, the Caucasus, Syria and Egypt. By the early 20th century, over half of the overall Greek-speaking population was settled in Asia Minor (now Turkey), while later that century a huge wave of migration to the United States, Australia, Canada and elsewhere created the modern Greek diaspora.

The massive work was arranged according to a "tree of knowledge." The tree reflected the marked division between the arts and sciences, which was largely a result of the rise of empiricism. Both areas of knowledge were united by philosophy, or the trunk of the tree of knowledge. The Enlightenment's desacrilization of religion was pronounced in the tree's design, particularly where theology accounted for a peripheral branch, with black magic as a close neighbour. As the Encyclopédie gained popularity, it was published in quarto and octavo editions after 1777. The quarto and octavo editions were much less expensive than previous editions, making the Encyclopédie more accessible to the non-elite. Robert Darnton estimates that there were approximately 25 000 copies of the Encyclopédie in circulation throughout France and Europe before the French Revolution. The extensive, yet affordable encyclopedia came to represent the transmission of Enlightenment and scientific education to an expanding audience.

In 1975 the US DOT conservatively identified a 0.7% reduction in traffic fatalities during DST, and estimated the real reduction at 1.5% to 2%, but the 1976 NBS review of the DOT study found no differences in traffic fatalities. In 1995 the Insurance Institute for Highway Safety estimated a reduction of 1.2%, including a 5% reduction in crashes fatal to pedestrians. Others have found similar reductions. Single/Double Summer Time (SDST), a variant where clocks are one hour ahead of the sun in winter and two in summer, has been projected to reduce traffic fatalities by 3% to 4% in the UK, compared to ordinary DST. However, accidents do increase by as much as 11% during the two weeks that follow the end of British Summer Time. It is not clear whether sleep disruption contributes to fatal accidents immediately after the spring clock shifts. A correlation between clock shifts and traffic accidents has been observed in North America and the UK but not in Finland or Sweden. If this effect exists, it is far smaller than the overall reduction in traffic fatalities. A 2009 US study found that on Mondays after the switch to DST, workers sleep an average of 40 minutes less, and are injured at work more often and more severely.

In 1609, while still there, Smyth wrote a tract titled "The Character of the Beast," or "The False Constitution of the Church." In it he expressed two propositions: first, infants are not to be baptized; and second, "Antichristians converted are to be admitted into the true Church by baptism." Hence, his conviction was that a scriptural church should consist only of regenerate believers who have been baptized on a personal confession of faith. He rejected the Separatist movement's doctrine of infant baptism (paedobaptism). Shortly thereafter, Smyth left the group, and layman Thomas Helwys took over the leadership, leading the church back to England in 1611. Ultimately, Smyth became committed to believers' baptism as the only biblical baptism. He was convinced on the basis of his interpretation of Scripture that infants would not be damned should they die in infancy.

Question: What is paedobaptism?
Answer: infant baptism.

For those with severe persistent asthma not controlled by inhaled corticosteroids and LABAs, bronchial thermoplasty may be an option. It involves the delivery of controlled thermal energy to the airway wall during a series of bronchoscopies. While it may increase exacerbation frequency in the first few months it appears to decrease the subsequent rate. Effects beyond one year are unknown. Evidence suggests that sublingual immunotherapy in those with both allergic rhinitis and asthma improve outcomes.

Senator Charles Schumer (D-NY) would later point out that brokered deposits made up more than 37 percent of IndyMac's total deposits and ask the Federal Deposit Insurance Corporation (FDIC) whether it had considered ordering IndyMac to reduce its reliance on these deposits. With $18.9 billion in total deposits reported on March 31, Senator Schumer would have been referring to a little over $7 billion in brokered deposits. While the breakout of maturities of these deposits is not known exactly, a simple averaging would have put the threat of brokered deposits loss to IndyMac at $500 million a month, had the regulator disallowed IndyMac from acquiring new brokered deposits on June 30.

Digimon was first conceived as a virtual pet toy in the vein of Tamagotchis and, as such, took influence from Tamagotchis' cute and round designs. The small areas of the screens (16 by 16 pixels) meant that character designers had to create monsters whose forms would be easily recognizable. As such, many of the early Digimon—including Tyrannomon, the first one ever created—were based on dinosaurs. Many further designs were created by Kenji Watanabe, who was brought in to help with the "X-Antibody" creatures and art for the Digimon collectible card game. Watanabe was one influenced by American comics, which were beginning to gain popularity in Japan, and as such began to make his characters look stronger and "cool." The character creation process, however, has for most of the franchise's history been collaborative and reliant on conversation and brainstorming.

Question: What was the screen size of the Digimon toy?
Answer: 16 by 16 pixels.

AC radio stations may play mainstream music, but they will exclude hip hop, dance tracks, hard rock, and some forms of teen pop, as they are less popular amongst the target demographic of these radio stations, which is intended for an adult audience. AC radio often targets the 25–44 age group, the demographic that has received the most attention from advertisers since the 1960s. A common practice in recent years is that many adult contemporary stations play less newer music because they also give ample airtime to hits of the past, so the de-emphasis on new songs slows the progression of the AC chart.

Question: What age group does adult contemporary radio typically focus on?
Answer: 25–44.

Although most hardware clones were not produced under license by Nintendo, certain companies were granted licenses to produce NES-compatible devices. The Sharp Corporation produced at least two such clones: the Twin Famicom and the SHARP 19SC111 television. The Twin Famicom was compatible with both Famicom cartridges and Famicom Disk System disks. It was available in two colors (red and black) and used hardwired controllers (as did the original Famicom), but it featured a different case design. The SHARP 19SC111 television was a television which included a built-in Famicom. A similar licensing deal was reached with Hyundai Electronics, who licensed the system under the name Comboy in the South Korean market. This deal with Hyundai was made necessary because of the South Korean government's wide ban on all Japanese "cultural products", which remained in effect until 1998 and ensured that the only way Japanese products could legally enter the South Korean market was through licensing to a third-party (non-Japanese) distributor (see also Japan–Korea disputes).

The Municipality of Montevideo was first created by a legal act of 18 December 1908. The municipality's first mayor (1909–1911) was Daniel Muñoz. Municipalities were abolished by the Uruguayan Constitution of 1918, effectively restored during the 1933 military coup of Gabriel Terra, and formally restored by the 1934 Constitution. The 1952 Constitution again decided to abolish the municipalities; it came into effect in February 1955. Municipalities were replaced by departmental councils, which consisted of a collegiate executive board with 7 members from Montevideo and 5 from the interior region. However, municipalities were revived under the 1967 Constitution and have operated continuously since that time.

The Somerset Coal Canal was built in the early 19th century to reduce the cost of transportation of coal and other heavy produce. The first 16 kilometres (10 mi), running from a junction with the Kennet and Avon Canal, along the Cam valley, to a terminal basin at Paulton, were in use by 1805, together with several tramways. A planned 11.7 km (7.3 mi) branch to Midford was never built, but in 1815 a tramway was laid along its towing path. In 1871 the tramway was purchased by the Somerset and Dorset Joint Railway (S&DJR), and operated until the 1950s.

The attacks were focused against western ports in March. These attacks produced some breaks in morale, with civil leaders fleeing the cities before the offensive reached its height. But the Luftwaffe's effort eased in the last 10 attacks as seven Kampfgruppen moved to Austria in preparation for the Balkans Campaign in Yugoslavia and Greece. The shortage of bombers caused the OKL to improvise. Some 50 Junkers Ju 87 Stuka dive-bombers and Jabos (fighter-bombers) were used, officially classed as Leichte Kampfflugzeuge ("light bombers") and sometimes called Leichte Kesselringe ("Light Kesselrings"). The defences failed to prevent widespread damage but on some occasions did prevent German bombers concentrating on their targets. On occasion, only one-third of German bombs hit their targets.

Question: Why was the OKL forced to improvise?
Answer: shortage of bombers.

One elector in Minnesota cast a ballot for president with the name of "John Ewards"  [sic] written on it. The Electoral College officials certified this ballot as a vote for John Edwards for president. The remaining nine electors cast ballots for John Kerry. All ten electors in the state cast ballots for John Edwards for vice president (John Edwards's name was spelled correctly on all ballots for vice president). This was the first time in U.S. history that an elector had cast a vote for the same person to be both president and vice president; another faithless elector in the 1800 election had voted twice for Aaron Burr, but under that electoral system only votes for the president's position were cast, with the runner-up in the Electoral College becoming vice president (and the second vote for Burr was discounted and re-assigned to Thomas Jefferson in any event, as it violated Electoral College rules).

Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second and third season, won by Committed and Pentatonix, respectively.
