Q: Lindstrom's theorem states that first-order logic is the strongest logic having both this property and satisfying the Lowenheim-Skolem property. A method for finding a Hausdorff space with this property containing a given space is named for Stone and Cech. Equicontinuity is the main condition for determining whether a family of functions has this property by the Arzela-Ascoli theorem. Using the axiom of choice, it can be shown that an arbitrary product of spaces with this property has this property, a result known as Tychonoff's theorem. In Euclidean space, being closed and bounded is sufficient to show, according to the Heine-Borel theorem, that a set has this property. For 10 points, identify this property which holds of a set on which every open cover has a finite subcover.

Q: 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.

Q: This man's writings include the unfinished novel M. Dudron's Adventure. This artist's fruit paintings include Transformed Dream, while a bunch of brightly-colored toys dominate his Evil Genius of a King. Nude men wading through pools is the subject of his set of prints entitled Mysterious Bathers, while paintings in a more classical style include the Horses by the Sea paintings. Experiments with lithography culminated in The Grand Metaphysician, while Still-Life with Silverware and Self-Portrait in Black Costume exemplify his "neo-baroque" period. He produced over twenty versions of his painting of three mannequins on a wooden pedestal, Disquieting Muses, but better-known are his "arcade paintings" including one featuring a girl rolling a large hoop in the shadowy title locale. For 10 points name this surrealist artist of Mystery and Melancholy of a Street.
