PROBLEM: A namesake protein component of this structure is detected by Toll-like Receptor 5. Tg737, whose mutation causes polycystic kidney disease in mice, is responsible for transport within this structure, which is also dependent upon complexes of IFT proteins. Y. Pestis uses a structure homologous to these to inject virulence factors into host cytoplasm, known as the Type III secretory system. They have a P, L, and MS ring in gram-negative bacteria, and in all organisms their central body is called the axonene. In Eukaryotes, they contain a 9+2 set of microtubules around a central pair and use dyenin and ATP hydrolysis to power their whipping motion. Similar to cilia, for 10 points, name these projections used by cells to swim.

SOLUTION: Science

PROBLEM: In June 2013, scientists found PAHs in this body's atmosphere. The Ligeia and Kraken Mares are found on this body, which undergoes a sort of "anti- greenhouse effect" due to the large concentration of organic molecules. This object, which is in resonance with Hyperion, has an orange smog caused by the breakup of methane in its atmosphere. Methane is also present in this moon's lakes. The Huygens portion of the Cassini-Huygens mission explored this moon. For 10 points, name this moon, the second largest in the solar system and the largest moon of Saturn.

SOLUTION: Science

PROBLEM: According to Charles Burney, its first use in an opera came in Johann Christian Bach's Orione. Two pioneering concertoes for it were written by F. X. Pokorny, while an early set of six concertoes for it was written by J. M. Molter. Max Reger wrote three sonatas for this instrument and piano, a combination also employed in Schumann's Opus 73, a set of three "fantasy pieces. "  Heinrich Baermann inspired Carl Maria von Weber to write two concertoes for it, while Hermstedt was the original soloist in the four concertoes for it by Louis Spohr. One of its early virtuosi was Anton Stadler, for whom the "Kegelstatt Trio" was composed by Mozart. More recent performers include Gervase de Payer, for whom Thea Musgrave wrote a concerto, and a man for whom Copland's concerto and Bartok's Contrasts were written. FTP, name this musical instrument, whose noted performers include Woody Herman, Artie Shaw, and Benny Goodman.
