In angiosperms, a hypanthium or floral cup is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. It often contains the nectaries of the plant. It is present in most flowering species, although varies in structural dimensions and appearance. This differentiation between the hypanthium in particular species is useful for identification. Some geometric forms are obconic shapes as in toyon, whereas some are saucer-shaped as in Mitella caulescens.
The Bromeliaceae are a family of monocot flowering plants of 51 genera and around 3475 known species native mainly to the tropical Americas, with a few species found in the American subtropics and one in tropical west Africa, Pitcairnia feliciana.
In physics and chemistry, ionization energy (American English spelling) or ionisation energy (British English spelling), denoted Ei, is the minimum amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated neutral gaseous atom or molecule. It is quantitatively expressed as
A raceme is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers along its axis. In botany, an axis means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. Cimicifuga racemosa. A compound raceme, also called a panicle, has a branching main axis. Examples of racemes occur on mustard and radish plants.
The tucuxi, alternatively in Peru bufeo gris or bufeo negro, is a species of freshwater dolphin found in the rivers of the Amazon basin. The word tucuxi is derived from the Tupi language word tuchuchi-ana, and has now been adopted as the species' common name. Despite being found in geographic locations similar to those of 'true' river dolphins such as the boto, the tucuxi is not closely related to them genetically. Instead, it is classed in the oceanic dolphin family (Delphinidae).
The Pacific cod, Gadus macrocephalus, is a species of ray-finned fish in the family Gadidae. It is a bottom-dwelling fish found in the northwestern Pacific Ocean, mainly on the continental shelf and upper slopes, to depths of about 900 m (3,000 ft). It can grow to a length of a meter or so and is found in large schools. It is an important commercial food species and is also known as gray cod or grey cod, and grayfish or greyfish. Fishing for this species is regulated with quotas being allotted for hook and line fishing, pots, and bottom trawls.
The tight end (TE) is a position in American football, arena football, and formerly Canadian football, on the offense. The tight end is often seen as a hybrid position with the characteristics and roles of both an offensive lineman and a wide receiver. Like offensive linemen, they are usually lined up on the offensive line and are large enough to be effective blockers. On the other hand, unlike offensive linemen, they are eligible receivers adept enough to warrant a defense's attention when running pass patterns.
Anthony David Gonzalez is a former American football tight end. He played college football and college basketball at University of California, Berkeley, and was recognized as a consensus All-American in football. He was drafted by the Kansas City Chiefs in the first round of the 1997 NFL Draft, where he played for 12 seasons, until being traded to the Atlanta Falcons, where he played for 5 seasons. Gonzalez, a 14-time Pro Bowl selection, holds the NFL record for total receiving yards (15,127) by a tight end. He also is second all-time in receptions with 1,325, trailing only wide receiver Jerry Rice. Gonzalez was known for his durability and rarely fumbling. During his career, he only missed two games and lost only two fumbles on 1,327 touches. He is currently an analyst on Fox NFL's pregame show. Gonzalez was inducted into the Pro Football Hall of Fame in August 2019, his first year of eligibility.
Marron is a name given to two closely related species of crayfish in Western Australia. Formerly considered a single species, it is now recognised as comprising two species, the critically endangered Cherax tenuimanus, and the species which is outcompeting it, Cherax cainii.
Hydnocarpus is a genus of medium to large trees of Indochina, Indonesia, Malaysia and the Philippines, having alternate leaves, small dioecious racemose flowers, and capsular fruits of which several are sources of chaulmoogra oil and hydnocarpus oil.
Incurvariidae is a family of small primitive monotrysian moths in the order Lepidoptera. There are twelve genera recognised. Many species are leaf miners and much is known of their host plants, excluding Paraclemensia acerifoliella. The most familiar species in Europe are perhaps Incurvaria masculella and Phylloporia bistrigella. The narrow wings are held tightly along the body at rest and some species have very long antennae.
The Batrachedridae are a small family of moths. These are small, slender moths which rest with their wings wrapped tightly around their bodies. The taxonomy of this and related groups is often disputed. It was long thought to contain two genera, Batrachedra and Houdinia.
Osmoxylon is a genus of flowering plants in the family Araliaceae.
Ammonitella is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Megomphicidae.
Clostridium enterotoxins are toxins produced by Clostridium species.
Robert James Gronkowski, nicknamed "Gronk", is a former American football tight end who played his entire professional career for the New England Patriots of the National Football League (NFL) until his retirement in March 2019. He is a three-time Super Bowl champion, a five-time Pro Bowl selection, four-time First Team All-Pro selection, and was the highest ranked tight end in the annual NFL Top 100 Players five times.
Tight oil is light crude oil contained in petroleum-bearing formations of low permeability, often shale or tight sandstone. Economic production from tight oil formations requires the same hydraulic fracturing and often uses the same horizontal well technology used in the production of shale gas. While sometimes called "shale oil", tight oil should not be confused with oil shale, which is shale rich in kerogen, or shale oil, which is oil produced from oil shales. Therefore, the International Energy Agency recommends using the term "light tight oil" for oil produced from shales or other very low permeability formations, while the World Energy Resources 2013 report by the World Energy Council uses the terms "tight oil" and "shale-hosted oil".
Acranthera is a genus of flowering plants in the family Rubiaceae. It is found from India to South Central China south to Borneo and the Philippines.
Thor's hero shrew is an extant species of shrew native to the Democratic Republic of the Congo. It and its sister species, the hero shrew, are the only mammal species known to have interlocking vertebrae.
The internal surface of the uterus is lined by uterine epithelial cells which undergo dramatic changes during pregnancy. The role of the uterine epithelial cells is to selectively allow the blastocyst to implant at a specific time. All other times of the cycle, these uterine epithelial cells are refractory to blastocyst implantation. Uterine epithelial cells have a similar structure in most species and the changes which occur in the uterine epithelial cells at the time of blastocyst implantation are also conserved among most species.
