On chemical grounds it seems most likely that iodide is first converted to Af and then to Af as the active iodinating species.

In the adult state they have tear ducts and movable eyelids and most species have ears that can detect airborne or ground vibrations.

Although most species are associated with water and damp habitats, some are specialised to live in trees and in deserts.

The suborder Neobatrachia is by far the largest group and includes the remaining families of modern frogs, including most common species.

In addition, most species of amphibian have granular glands that secrete distasteful or poisonous substances.

Larvae and most aquatic adult amphibians excrete the nitrogen as ammonia in large quantities of dilute urine while terrestrial species, with a greater need to conserve water, excrete the less toxic product urea.

In air, where oxygen is more concentrated, some small species can rely solely on cutaneous gas exchange, most famously the plethodontid salamanders, which have neither lungs nor gills.

In many species of frog and in most lungless salamanders ( Plethodontidae ), direct development takes place, the larvae growing within the eggs and emerging as miniature adults.

Tadpoles do not have true teeth but, in most species, the jaws have long, parallel rows of small keratinized structures called keradonts surrounded by a horny beak.

In most species, the sound is produced by expelling air from the lungs over the vocal cords into an air sac or sacs in the throat or at the corner of the mouth.

Although in many frog species, females are larger than males, this is not the case in most species where males are actively involved in territorial defence.

One seed-to-seed life cycle for an annual can occur in as little as a month in some species, though most last several months.

Thus although most species in the order are herbaceous, some no more than 15 cm high, there are a number of climbers ( e. g. some species of Asparagus ), as well as several genera forming trees ( e. g. Agave, Cordyline, Yucca, Dracaena ), some of which can exceed 10 m in height.

The order is a cosmopolite ( plants found throughout most of the world including desert and frigid zones ), and includes mostly herbaceous species, although a small number of trees ( such as the giant Lobelia and the giant Senecio ) and shrubs are also present.

Although most extant species of Asteraceae are herbaceous, the examination of the basal members in the family suggests that the common ancestor of the family was an arborescent plant, a tree or shrub, perhaps adapted to dry conditions, radiating from South America.

** Eunectes beniensis, the Bolivian anaconda, the most recently defined species, is found in the Departments of Beni and Pando in Bolivia.

However, this name is used to refer to the brown vine snake, Ahaetulla pulverulenta, a slender, arboreal species that grows to five feet ( 152 cm ) at most and feeds only on small vertebrates.

A number of species have come to be considered invasive, including, most notably in North America, dandelion, which was originally introduced by European settlers who used the young leaves as a salad green.

The abbey is a species of " exempt religious " in that it is, for the most part, answerable to the Pope, or to the abbot primate, rather than to the local bishop.

The most comprehensive treatment of the family considers 56 species valid, with 18 additional subspecies.

The Andes is rich in fauna: With almost 3, 500 species, of which roughly 2 / 3 are endemic to the region, the Andes is the most important region in the world for amphibians.

Resin from the extinct species Hymenaea protera is the source of Dominican amber and probably of most amber found in the tropics.

The largest species are red alder ( A. rubra ) on the west coast of North America, and black alder ( A. glutinosa ), native to most of Europe and widely introduced elsewhere, both reaching over 30 m. By contrast, the widespread Alnus viridis ( green alder ) is rarely more than a 5 m tall shrub.

Over these voluntary agencies, in 1917-18, the CTCA served as a co-ordinating body in carrying out what Survey called `` the most stupendous piece of social work in modern times ''.

The subject he liked most was the female body, which he painted in every state -- naked, half-dressed, muffled to the ears, sitting primly in a chair, lying tauntingly on a bed or locked in an embrace.

At one time, to most Americans, unless they were fortunate enough to live near a body of navigable water, boats were considered the sole concern of fishermen, rich people, and the United States Navy.

One of the most gratifying applications of an important technique of submarine detection is in the exploration of the human body.

It has been the custom for most universities to stretch the blanket of accreditation for their liberal arts school to cover the shivering body of their fine arts department.

Shell people resembled mature dwarfs in size whatever their natal deformities were, but the well-oriented brain would not have changed places with the most perfect body in the Universe.

Though equipped with limbs and the ability to breathe air, most still had a long tapering body and strong tail.

In most salamanders, the limbs are short and more or less the same length and project at right angles from the body.

Because most embryonic development is outside the parental body, it is subject to many adaptations due to specific ecological circumstances.

Abscesses in most parts of the body rarely heal themselves, so prompt medical attention is indicated at the first suspicion of an abscess.

In most developed countries, only qualified persons — those with the appropriate licensure, certification, or registration with a relevant body, often governmental — are legally permitted to practice architecture.

He was endowed by nature with the most remarkable gifts both of mind and body: he was handsome and eloquent, but licentious ; and, at the same time, active, hardy, courageous, a great general and an able politician.

Rodin's most original work departed from traditional themes of mythology and allegory, modeled the human body with realism, and celebrated individual character and physicality.

* A " 00 ", " Double-Oh " or " Grand Concert " body style is the major body style most directly derived from the classical guitar.

* A " Dreadnought ", arguably the most common body style, incorporates a deeper soundbox, but a smaller and less-pronounced upper bout ( the area of the soundbox between the waist and neck ) than most styles, giving a somewhat wedge-shaped appearance – hence its name, relating to a class of warship.

The form used in the Roman Rite included anointing of seven parts of the body while saying ( in Latin ): " Through this holy unction and His own most tender mercy may the Lord pardon thee whatever sins or faults thou hast committed deliquisti by sight hearing, smell, taste, touch, walking, carnal delectation ", the last phrase corresponding to the part of the body that was touched ; however, in the words of the 1913 Catholic Encyclopedia, " the unction of the loins is generally, if not universally, omitted in English-speaking countries, and it is of course everywhere forbidden in case of women ".

The AFL, currently with 18 member clubs, is the sport's elite competition and the most powerful body and continues to seek further opportunities to expand into new markets.

This accompanied or facilitated other important evolutionary developments: the bilaterian body plan ; the coelom, an internal cavity that provided space for a circulatory system and, in some animals, formed a hydrostatic skeleton which enables worm-like animals to burrow ; metamerism, in which the body was built of repeated " modules " which could later specialize, for example the heads of most arthropods are composed of fused, specialized segments.

The brain of a vertebrate is the most complex organ of its body.

The brain is small and simple in some species, such as nematode worms ; in other species, including vertebrates, it is the most complex organ in the body.

In addition to the six major elements that compose most of the human body, humans require smaller amounts of possibly 18 more.
