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.

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.

Some of the earliest recordings, made in the 1940's demonstrated that psychiatrists reacted immediately to anger and anxiety in the sound track, whereas written records of the same interview offered far fewer cues to therapy which -- if they were at all discernible in print -- were picked up only by the most skilled and sensitive experts.

In a general way, psychiatrists were able to establish on a wide basis what many of them had always felt -- that the most telling cues in psychotherapy are acoustic, that such things as stress and nagging are transmitted by sound alone and not necessarily by words.

Elaine Stritch, who sings with a persuasively warm huskiness, belts some life into most of her songs, but the other members of the cast sound as lukewarm as Mr. Coward's songs.

Since in oral languages the elements of sound are for the most part produced linearly in time ( that is, in a word like cat the a sound comes after the c sound, and the t sound comes after that ), they can generally be easily written in a linear ( one-dimensional ) writing system such as an alphabet.

In most varieties of North American English, the sound corresponding to the letter r is an alveolar approximant or retroflex rather than a trill or a tap.

Although the hardware is limited to four separate sound channels, software such as OctaMED uses software mixing to allow eight or more virtual channels, and it was possible for software to mix two hardware channels to achieve a single 14-bit resolution channel by playing with the volumes of the channels in such a way that one of the source channels contributes the most significant bits and the other the least.

They became prized for their distinctive sound, however, and found life with several musical styles ( most notably bluegrass and also blues ) well after electric amplification solved the issue of inadequate guitar sound levels.

Is the most common sound file format used today.

In 1957, it produced a pocket-sized radio ( the first to be fully transistorized ), and in 1958, Morita and Ibuka decided to rename their company Sony ( sonus is Latin for sound, and Sonny-boys the most common American expression ).

This rule obtains in most Eastern dialects, although some have " ya ", or a special " open e " sound, in all positions.

The view of most scholars ( see organology ) is that the term " brass instrument " should be defined by the way the sound is made, as above, and not by whether the instrument is actually made of brass.

Although Hole's sound changed over the course of the band's career, the pretty / ugly dynamic has often been noted as a consistent theme in Love's music, most prominently in Hole's first two studio albums.

The " sh " sound was dropped and in most, but not all, cases accompanied by a change of spelling (" x " to " j ").

This thin ( often 2 or 3 mm thick ) piece of wood, strengthened by different types of internal bracing, is considered the most prominent factor in determining the sound quality of a guitar.

In the 1980s, Japanese personal computers such as the NEC PC-88 came installed with FM synthesis sound chips and featured audio programming languages such as Music Macro Language ( MML ) and MIDI interfaces, which were most often used to produce video game music, or chiptunes.

These are most often large – bore instruments with a rich mellow sound.

Because of this intimate contact between the player's hand and the production of sound, the clavichord has been referred to as the most intimate of keyboard instruments.

While most may think that the body of the drum produces the sound, it is in fact actually the membrane and its vibration that creates the sound when struck.

In most disco tracks, strings, horns, electric pianos, and electric guitars create a lush background sound.
