Epigenetics is the study of mitotically and/or meiotically heritable changes in gene function that cannot be explained by changes in the underlying DNA sequence but cause the organism's genes to behave (or "express themselves") differently. One example of epigenetic change is the marking of the genes by DNA methylation which determines whether they will be expressed or not. Gene expression can also be controlled by repressor proteins that attach to silencer regions of the DNA and prevent that region of the DNA code from being expressed. Epigenetic marks may be added or removed from the DNA during programmed stages of development of the plant, and are responsible, for example, for the differences between anthers, petals and normal leaves, despite the fact that they all have the same underlying genetic code. Epigenetic changes may be temporary or may remain through successive cell divisions for the remainder of the cell's life. Some epigenetic changes have been shown to be heritable, while others are reset in the germ cells.

Question: When DNA has different markers, how it that presented in plants?

Several animal phyla are recognized for their lack of bilateral symmetry, and are thought to have diverged from other animals early in evolution. Among these, the sponges (Porifera) were long thought to have diverged first, representing the oldest animal phylum. They lack the complex organization found in most other phyla. Their cells are differentiated, but in most cases not organized into distinct tissues. Sponges typically feed by drawing in water through pores. However, a series of phylogenomic studies from 2008-2015 have found support for Ctenophora, or comb jellies, as the basal lineage of animals. This result has been controversial, since it would imply that that sponges may not be so primitive, but may instead be secondarily simplified. Other researchers have argued that the placement of Ctenophora as the earliest-diverging animal phylum is a statistical anomaly caused by the high rate of evolution in ctenophore genomes.

Question: How do sponges typically feed?
Answer: drawing in water through pores.

Stereophonic sound recording, which attempts to provide a more natural listening experience by reproducing the spatial locations of sound sources in the horizontal plane, was the natural extension to monophonic recording, and attracted various alternative engineering attempts. The ultimately dominant "45/45" stereophonic record system was invented by Alan Blumlein of EMI in 1931 and patented the same year. EMI cut the first stereo test discs using the system in 1933 (see Bell Labs Stereo Experiments of 1933) although the system was not exploited commercially until much later.

Cotton lisle is a finely-spun, tightly twisted type of cotton that is noted for being strong and durable. Lisle is composed of two strands that have each been twisted an extra twist per inch than ordinary yarns and combined to create a single thread. The yarn is spun so that it is compact and solid. This cotton is used mainly for underwear, stockings, and gloves. Colors applied to this yarn are noted for being more brilliant than colors applied to softer yarn. This type of thread was first made in the city of Lisle, France (now Lille), hence its name.

Eisenhower retired to the place where he and Mamie had spent much of their post-war time, a working farm adjacent to the battlefield at Gettysburg, Pennsylvania, only 70 miles from his ancestral home in Elizabethville, Dauphin County, Pennsylvania. In 1967 the Eisenhowers donated the farm to the National Park Service. In retirement, the former president did not completely retreat from political life; he spoke at the 1964 Republican National Convention and appeared with Barry Goldwater in a Republican campaign commercial from Gettysburg. However, his endorsement came somewhat reluctantly because Goldwater had attacked the former president as "a dime-store New Dealer".

The MP3 lossy audio data compression algorithm takes advantage of a perceptual limitation of human hearing called auditory masking. In 1894, the American physicist Alfred M. Mayer reported that a tone could be rendered inaudible by another tone of lower frequency. In 1959, Richard Ehmer described a complete set of auditory curves regarding this phenomenon. Ernst Terhardt et al. created an algorithm describing auditory masking with high accuracy. This work added to a variety of reports from authors dating back to Fletcher, and to the work that initially determined critical ratios and critical bandwidths.

Eritrea is a multilingual country. The nation has no official language, as the Constitution establishes the "equality of all Eritrean languages". However, Tigrinya serves as the de facto language of national identity. With 2,540,000 total speakers of a population of 5,254,000 in 2006, Tigrinya is the most widely spoken language, particularly in the southern and central parts of Eritrea. Modern Standard Arabic and English serve as de facto working languages, with the latter used in university education and many technical fields. Italian, the former colonial language, is widely used in commerce and is taught as a second language in schools, with a few elderly monolinguals.

The decisive engagement of the war came when Lysimachus invaded and overran much of western Anatolia, but was soon isolated by Antigonus and Demetrius near Ipsus in Phrygia. Seleucus arrived in time to save Lysimachus and utterly crushed Antigonus at the Battle of Ipsus in 301 BCE. Seleucus' war elephants proved decisive, Antigonus was killed, and Demetrius fled back to Greece to attempt to preserve the remnants of his rule there by recapturing a rebellious Athens. Meanwhile, Lysimachus took over Ionia, Seleucus took Cilicia, and Ptolemy captured Cyprus.

The Manchester Small-Scale Experimental Machine, nicknamed Baby, was the world's first stored-program computer. It was built at the Victoria University of Manchester by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948. It was designed as a testbed for the Williams tube the first random-access digital storage device. Although the computer was considered "small and primitive" by the standards of its time, it was the first working machine to contain all of the elements essential to a modern electronic computer. As soon as the SSEM had demonstrated the feasibility of its design, a project was initiated at the university to develop it into a more usable computer, the Manchester Mark 1.

Because of his ability to motivate nationalistic passions, "men, women, and children wept and wailed in the streets" after hearing of his death, according to Nutting. The general Arab reaction was one of mourning, with thousands of people pouring onto the streets of major cities throughout the Arab world. Over a dozen people were killed in Beirut as a result of the chaos, and in Jerusalem, roughly 75,000 Arabs marched through the Old City chanting, "Nasser will never die." As a testament to his unchallenged leadership of the Arab people, following his death, the headline of the Lebanese Le Jour read, "One hundred million human beings—the Arabs—are orphans." Sherif Hetata, a former political prisoner and later member Nasser's ASU, said that "Nasser's greatest achievement was his funeral.

Jehovah's Witnesses have been accused of having policies and culture that help to conceal cases of sexual abuse within the organization. The religion has been criticized for its "two witness rule" for church discipline, based on its application of scriptures at Deuteronomy 19:15 and Matthew 18:15-17, which requires sexual abuse to be substantiated by secondary evidence if the accused person denies any wrongdoing. In cases where corroboration is lacking, the Watch Tower Society's instruction is that "the elders will leave the matter in Jehovah's hands". A former member of the church’s headquarters staff, Barbara Anderson, says the policy effectively requires that there be another witness to an act of molestation, "which is an impossibility". Anderson says the policies "protect pedophiles rather than protect the children." Jehovah's Witnesses maintain that they have a strong policy to protect children, adding that the best way to protect children is by educating parents; they also state that they do not sponsor activities that separate children from parents.

Polemics about humanism have sometimes assumed paradoxical twists and turns. Early 20th century critics such as Ezra Pound, T. E. Hulme, and T. S. Eliot considered humanism to be sentimental "slop" (Hulme)[citation needed] or "an old bitch gone in the teeth" (Pound) and wanted to go back to a more manly, authoritarian society such as (they believed) existed in the Middle Ages. Postmodern critics who are self-described anti-humanists, such as Jean-François Lyotard and Michel Foucault, have asserted that humanism posits an overarching and excessively abstract notion of humanity or universal human nature, which can then be used as a pretext for imperialism and domination of those deemed somehow less than human. "Humanism fabricates the human as much as it fabricates the nonhuman animal", suggests Timothy Laurie, turning the human into what he calls "a placeholder for a range of attributes that have been considered most virtuous among humans (e.g. rationality, altruism), rather than most commonplace (e.g. hunger, anger)". Nevertheless, philosopher Kate Soper notes that by faulting humanism for falling short of its own benevolent ideals, anti-humanism thus frequently "secretes a humanist rhetoric".

This is not to say that Whitehead's thought was widely accepted or even well-understood. His philosophical work is generally considered to be among the most difficult to understand in all of the western canon. Even professional philosophers struggled to follow Whitehead's writings. One famous story illustrating the level of difficulty of Whitehead's philosophy centers around the delivery of Whitehead's Gifford lectures in 1927–28 – following Arthur Eddington's lectures of the year previous – which Whitehead would later publish as Process and Reality:

Napoleon established a political system that historian Martyn Lyons called "dictatorship by plebiscite." Worried by the democratic forces unleashed by the Revolution, but unwilling to ignore them entirely, Napoleon resorted to regular electoral consultations with the French people on his road to imperial power. He drafted the Constitution of the Year VIII and secured his own election as First Consul, taking up residence at the Tuileries. The constitution was approved in a rigged plebiscite held the following January, with 99.94 percent officially listed as voting "yes." Napoleon's brother, Lucien, had falsified the returns to show that 3 million people had participated in the plebiscite; the real number was 1.5 million. Political observers at the time assumed the eligible French voting public numbered about 5 million people, so the regime artificially doubled the participation rate to indicate popular enthusiasm for the Consulate. In the first few months of the Consulate, with war in Europe still raging and internal instability still plaguing the country, Napoleon's grip on power remained very tenuous.

Birds have one of the most complex respiratory systems of all animal groups. Upon inhalation, 75% of the fresh air bypasses the lungs and flows directly into a posterior air sac which extends from the lungs and connects with air spaces in the bones and fills them with air. The other 25% of the air goes directly into the lungs. When the bird exhales, the used air flows out of the lung and the stored fresh air from the posterior air sac is simultaneously forced into the lungs. Thus, a bird's lungs receive a constant supply of fresh air during both inhalation and exhalation. Sound production is achieved using the syrinx, a muscular chamber incorporating multiple tympanic membranes which diverges from the lower end of the trachea; the trachea being elongated in some species, increasing the volume of vocalizations and the perception of the bird's size.

Question: Where does the other 25 percent of fresh air go?

An exhibition game (also known as a friendly, a scrimmage, a demonstration, a preseason game, a warmup match, or a preparation match, depending at least in part on the sport) is a sporting event whose prize money and impact on the player's or the team's rankings is either zero or otherwise greatly reduced. In team sports, matches of this type are often used to help coaches and managers select players for the competitive matches of a league season or tournament. If the players usually play in different teams in other leagues, exhibition games offer an opportunity for the players to learn to work with each other. The games can be held between separate teams or between parts of the same team.

Alfred North Whitehead was born in Ramsgate, Kent, England, in 1861. His father, Alfred Whitehead, was a minister and schoolmaster of Chatham House Academy, a successful school for boys established by Thomas Whitehead, Alfred North's grandfather. Whitehead himself recalled both of them as being very successful schoolmasters, but that his grandfather was the more extraordinary man. Whitehead's mother was Maria Sarah Whitehead, formerly Maria Sarah Buckmaster. Whitehead was apparently not particularly close with his mother, as he never mentioned her in any of his writings, and there is evidence that Whitehead's wife, Evelyn, had a low opinion of her.
