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: Even though the voting in this nation occurred on March 29, the results have still not been provided, especially since a High Court hearing has officially requested a recount in a number of provinces. The election has been fraught with bad news for the incumbent, with a split ruling party divided through the rise of Simba Makoni and the rise in inflation far above 1,000%. Thus, Morgan Tsvangirais MDC party has been widely declared the winners both in the parliamentary and presidential struggle. FTP; name this nation who may soon see the unseating of their current ruler, Robert Mugabe.

SOLUTION: History

PROBLEM: David Jewitt and Jane Luu utilized a blink comparator to discover the first objects part of it, which were named Cubewanos after the prototype QB1. Possessing gaps due to orbital resonance, its size fluctuates from 2:3 resonance to 1:2 resonance. With its mean position inclined by 1.86 degrees, it resembles a torus. The discovery of Eris, an object in it, disproved the Titius-Bode Law governing the size of the semi-major axis of heavenly bodies. Sedna, Pluto and other Plutinos are, for 10 points, part of what astronomical structure beyond Neptune that is thought to be the home of many short-period comets
