| kingdom | <biology> The highest taxonomic rank, immediately above phylum or division. There are five biological kingoms: 1. Kingdom animalia: The members of this kingom are complex, multicellular, eukaryotic organisms that digest food outside their cells and then absorb the digested nutrients. Animals must consume other organisms to obtain most of their nutrients. 2. Kingdom fungi: Kingdom Fungi includes organisms such as slime moulds, mushrooms, smuts, rusts, mildews, moulds, stinkhorns, puffballs, truffles and yeasts. Allare classified in this kingdom because they absorb food in solution directly through their cell walls and reproduce through spores. None conduct photosynthesis. 3. Kingdom monera: This is the most primitive of the five kingdoms, it encompasses all the bacteria. Monerans are single-celled prokaryotic organisms. 4. Kingdom plantae: The members of this kingdom are multicellular, eukaryotic organisms that (usually) conduct photosynthesis. 5. Kingdom protista: This kingdom is composed of single-celled (sometimes multicellular), eukaryotic organisms. Protists are more complex than bacteria and include protozooans and some types of algae.

It is slate-blue above, with a white belly and breast, and a broad white ring around the neck. A dark band crosses the breast. The common European species (Alcedo ispida), which is much smaller and brighter coloured, is also a fisher. See Alcedo. The wood kingfishers (Halcyones), which inhabit forests, especially in Africa, feed largely upon insects, but also eat reptiles, snails, and small Crustacea, as well as fishes. The giant kingfisher of Australia feeds largely upon lizards and insects. See Laughing jackass, under Laughing. Source: Websters Dictionary (01 Mar 1998) |

| kingly | Belonging to, suitable to, or becoming, a king; characteristic of, resembling, a king; directed or administered by a king; monarchical; royal; sovereign; regal; august; noble; grand. "Kingly magnificence." . "A kingly government." . "The kingly couch." "The kingliest kings are crowned with thorn." (G. Massey) "Leave kingly backs to cope with kingly cares." (Cowper) Synonym: Regal, royal, monarchical, imperial, august, sovereign, noble, splendid. Kingly, Regal. Kingly is Anglo-Saxon, and refers especially to the character of a king; regal is Latin, and now relates more to his office. The former is chiefly used of dispositions, feelings, and purposes which are kinglike; as, kingly sentiments; kingly condescension; " a kingly heart for enterprises." . The latter is oftener applied to external state, pomp, etc.; as, regal state, regal title, etc. This distinction is not observed by our early writers, but is gaining ground. Origin: Kinglier; Kingliest. In a kingly or kinglike manner. "Low bowed the rest; he, kingly, did but nod." (Pore) Although this citation, one from Paradise Lost, and one from Shakespeare's ll4th Sonnet are given by lexicographers as examples of adverbial use, it is by no means clear that the word is not an adjective in each instance.

| kinase |
A kinase is an enzyme that transfers a phosphate group from ATP to some molecule. For example, glucokinase phosphorylates glucose, using ATP. Hexokinase phosphorylates hexoses, using ATP. A protein kinase phosphorylates a protein, using ATP; this is an important type of reaction in biochemistry, as the phosphorylation modulates the shape -- and hence the activity -- of proteins.
