Gill

A gill (ⁱ/ɡɪl/) is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment.

Many microscopic aquatic animals, and some larger but inactive ones, can absorb adequate oxygen through the entire surface of their bodies, and so can respire adequately without a gill. However, more complex or more active aquatic organisms usually require a gill or gills.

Gills usually consist of thin filaments of tissue, branches, or slender, tufted processes that have a highly folded surface to increase surface area. A high surface area is crucial to the gas exchange of aquatic organisms, as water contains only a small fraction of the dissolved oxygen that air does. A cubic meter of air contains about 250 grams of oxygen at STP. The concentration of oxygen in water is lower than air and it diffuses more slowly. In fresh water, the dissolved oxygen content is approximately 8 cm³/L compared to that of air which is 210 cm³/L. Water is 777 times more dense than air and is 100 times more viscous. Oxygen has a diffusion rate in air 10,000 times greater than in water. The use of sac-like lungs to remove oxygen from water would not be efficient enough to sustain life. Rather than using lungs, "[g]asesous exchange takes place across the surface of highly vascularised gills over which a one-way current of water is kept flowing by a specialised pumping mechanism. The density of the water prevents the gills from collapsing and lying on top of each other, which is what happens when a fish is taken out of water."

List of Kim Possible characters

This is a list of characters appearing in the animated series Kim Possible.

Team Possible

Kim Possible

Kimberly Ann "Kim" Possible is a crime fighter and high school cheerleading captain who saves the world on a regular basis while dealing with the normal challenges of a teenager, such as winning cheer competitions, turning in her homework on time, and maintaining a love life. Her name is a play on the word "impossible." Kim has known Ron Stoppable, her sidekick for most missions, since preschool. She has also completed missions with Wade, Monique, her brothers, and even her mother. Kim and Ron end up developing romantic feelings for each other and begin dating during their senior year, in Season 4. She famously adopts untypical teen slang such as "So not the drama", "No big" ("no big deal"), as well as the series' catch phrase, "What's the sitch?" (slang for "situation") in her speech. At Middleton High School, she is popular and charismatic, as well as an excellent student. She has an irritable and demanding personality that often affects her work, yet she fulfills the role of a protagonist by using her intelligence and sensibility to 'save the day'. Though she struggles with embarrassment, her rivalry with Bonnie, and her shyness around her crushes, she usually displays extreme maturity, going so far as to act as Ron's conscience at times. She has a good relationship with her family members, though she is often annoyed by her brothers (whom she calls "Tweebs", for "Twin Dweebs"), and embarrassed by her parents' antics.

Thomas'

Thomas' is a brand of English muffins and bagels in North America. It is owned by Bimbo Bakeries USA, which also owns Entenmann's, Boboli, Stroehmann, and Arnold bread companies. It advertises as having "nooks and crannies" in the muffins. The company also produces toasting/swirl breads, pitas, bagels and wraps.

The company was founded by Samuel Bath Thomas (1855–1919). In 1874, he emigrated from England to New York City and began working in a bakery. By 1880, he had purchased his own bakery at 163 Ninth Avenue, where he featured his namesake muffins. Thomas expanded to 337 West 20th Street where today a plaque designates the building as "The Muffin House."

The company, S.B. Thomas, Inc., was incorporated by his family after his death in 1919.

Trade Secrets Case

In 2010, the company won a trade secret suit when an executive downloaded the company's recipes and retired to work for Hostess.

Thomas the Apostle

Saint Thomas the Apostle (called Didymus which means "the twin") was one of the Twelve Apostles of Jesus Christ, according to the New Testament. He is informally called doubting Thomas because he doubted Jesus' resurrection when first told, (in the Gospel of John), followed later by his confession of faith, "My Lord and my God", on seeing Jesus' wounded body.

Traditionally, he is said to have travelled outside the Roman Empire to preach the Gospel, travelling as far as Tamilakam in present-day India. According to tradition, the Apostle reached Muziris, Tamilakam present day India in AD 52 and baptized several people, founding what today are known as Saint Thomas Christians or Nasranis. After his death, the reputed relics of Saint Thomas the Apostle were enshrined as far as Mesopotamia in the 3rd century, and later moved to various places. In 1258, some of the relics were brought to Abruzzo in Ortona, Italy, where they have been held in the Church of Saint Thomas the Apostle. He is often regarded as the Patron Saint of India, and the name Thoma remains quite popular among Saint Thomas Christians of India.

Thomas (bishop of Finland)

Thomas is the first known Bishop of Finland. Only a few facts are known about his life. He resigned in 1245 and died in Visby three years later.

Biography

The only reference to Bishop Thomas during his episcopate in Finland is a letter signed by him in Nousiainen in 1234, which granted certain lands around the parish to his chaplain Wilhelm. The lands may be related to the papal permission from Pope Gregory IX in early 1229 that authorized the church to take over all non-Christian places of worship in Finland. The letter is the oldest surviving letter written in Finland.

No further information on the bishop's activities has survived before he was granted resignation by Pope Innocent IV on 21 February 1245. According to the Pope, Thomas had admitted committing several felonies, such as torturing a man to death, and forging a papal letter. Church representatives to oversee the resignation were the Archbishop of Uppsala and the Dominican prior of the Dacian province. Thomas donated his books to the newly established Dominican convent in Sigtuna and went on to live his last years in the Dominican convent in Visby, Gotland. He died there in 1248, shortly before the Second Swedish Crusade which cemented the Swedish rule in Finland for more than 550 years.
