Brain

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

Physiologically, the function of the brain is to exert centralized control over the other organs of the body. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain.

Lilium

Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have "lily" in their common name but are not related to true lilies.

Description

Lilies are tall perennials ranging in height from 2–6 ft (60–180 cm). They form naked or tunicless scaly underground bulbs which are their overwintering organs. In some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found. Some species develop stolons. Most bulbs are deeply buried, but a few species form bulbs near the soil surface. Many species form stem-roots. With these, the bulb grows naturally at some depth in the soil, and each year the new stem puts out adventitious roots above the bulb as it emerges from the soil. These roots are in addition to the basal roots that develop at the base of the bulb.

The X Factor

The X Factor is a television music competition franchise created by Simon Cowell. It originated in the United Kingdom, where it was devised as a replacement for Pop Idol (2001–2003). It is held in various countries. The programmes are produced by executive producer Simon Cowell and his company SYCOtv. The "X Factor" of the title refers to the undefinable "something" that makes for star quality. The prize is usually a recording contract, in addition to the publicity that appearance in the later stages of the show itself generates, not only for the winner but also for other highly ranked contestants.

The similarities between The X Factor and Idols prompted Idol creator Simon Fuller, along with 19 Entertainment, to file a lawsuit against Cowell, SYCOtv, and FremantleMedia in 2004. An out-of-court settlement was reached in 2005 allowing Fuller to gain a 10% share in The X Factor format, and preventing an American version until 2010. Fuller later filed another lawsuit in 2011, claiming that he had also been promised that he would be credited as an executive producer of The X Factor USA, but that Syco, FremantleMedia, and Fox Broadcasting Company had failed to fulfill that promise; that lawsuit is pending.

The Tonight Show

The Tonight Show is an American late-night talk show broadcast from the Rockefeller Center in New York City and airing on NBC since 1954. It is the world's longest-running talk show, and the longest running, regularly scheduled entertainment program in the United States. It is the third-longest-running show on NBC, after only the news-and-talk shows Today and Meet the Press.

Over the course of more than 60 years, The Tonight Show has undergone only minor title changes. It aired under the name Tonight for several of its early years, eventually settling on The Tonight Show after the seating of long-time host Johnny Carson in 1962. In later decades, network programmers, advertisers, and the show's announcers would refer to the show by including the name of the host; for example, it is currently announced as The Tonight Show Starring Jimmy Fallon. In 1957, the show briefly tried a more news-style format. It has otherwise remained a talk show throughout its run.

The Tonight Show began broadcasting in 1954. It has had six official hosts, beginning with Steve Allen (1954–57), followed by Jack Paar (1957–62), Johnny Carson (1962–92), Jay Leno (1992–2009, 2010–14), Conan O'Brien (2009–10), and Jimmy Fallon (2014–present). It has had several recurring guest hosts, a practice especially common during the Paar and Carson eras.
