- Domain (biology) (Wikipedia)
In biological taxonomy, a domain (/dəˈmeɪn/ or /doʊˈmeɪn/) (Latin: regio), also dominion, superkingdom, realm, or empire, is the highest taxonomic rank of all organisms taken together. It was introduced in the three-domain system of taxonomy devised by Carl Woese, Otto Kandler and Mark Wheelis in 1990.
- Flute (Wikipedia)
The flute is a member of a family of musical instruments in the woodwind group. Like all woodwinds, flutes are aerophones, producing sound with a vibrating column of air. Unlike woodwind instruments with reeds, a flute produces sound when the player’s air flows across an opening. In the Hornbostel–Sachs classification system, flutes are edge-blown aerophones. A musician who plays the flute is called a flautist or flutist.
