Uranium was also used in photographic chemicals (especially uranium nitrate as a toner), in lamp filaments for stage lighting bulbs, to improve the appearance of dentures, and in the leather and wood industries for stains and dyes. Uranium salts are mordants of silk or wool. Uranyl acetate and uranyl formate are used as electron-dense "stains" in transmission electron microscopy, to increase the contrast of biological specimens in ultrathin sections and in negative staining of viruses, isolated cell organelles and macromolecules.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Along with uranyl formate, what product of uranium is used in transmission proton microscopy?
Ah, so.. unanswerable

American Idol was based on the British show Pop Idol created by Simon Fuller, which was in turn inspired by the New Zealand television singing competition Popstars. Television producer Nigel Lythgoe saw it in Australia and helped bring it over to Britain. Fuller was inspired by the idea from Popstars of employing a panel of judges to select singers in audition. He then added other elements, such as telephone voting by the viewing public (which at the time was already in use in shows such as the Eurovision Song Contest), the drama of backstories and real-life soap opera unfolding in real time. The show debuted in 2001 in Britain with Lythgoe as showrunnerthe executive producer and production leaderand Simon Cowell as one of the judges, and was a big success with the viewing public.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who saw Popstars while in Australia and wanted Britain to have the same thing?
Ah, so.. Nigel Lythgoe

Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the Appalachian Highlands physiographic division as consisting of thirteen provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Megantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, Saint Lawrence Valley, Appalachian Plateaus, New England province, and the Adirondack provinces. A common variant definition does not include the Adirondack Mountains, which geologically belong to the Grenville Orogeny and have a different geological history from the rest of the Appalachians.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What has a similar geological history to the Appalachians?
Ah, so..
