PROBLEM: Recently, the Air Force refined its understanding of the core duties and responsibilities it performs as a Military Service Branch, streamlining what previously were six distinctive capabilities and seventeen operational functions into twelve core functions to be used across the doctrine, organization, training, equipment, leadership, and education, personnel, and facilities spectrum. These core functions express the ways in which the Air Force is particularly and appropriately suited to contribute to national security, but they do not necessarily express every aspect of what the Air Force contributes to the nation. It should be emphasized that the core functions, by themselves, are not doctrinal constructs.

SOLUTION: How many core functions did the Air Force reduce its duties down to recently?

PROBLEM: While photosystem II photolyzes water to obtain and energize new electrons, photosystem I simply reenergizes depleted electrons at the end of an electron transport chain. Normally, the reenergized electrons are taken by NADP+, though sometimes they can flow back down more H+-pumping electron transport chains to transport more hydrogen ions into the thylakoid space to generate more ATP. This is termed cyclic photophosphorylation because the electrons are recycled. Cyclic photophosphorylation is common in C4 plants, which need more ATP than NADPH.

SOLUTION: What usually takes reenergized electrons?

PROBLEM: Tourism accounts for much of Uruguay's economy. Tourism in Montevideo is centered in the Ciudad Vieja area, which includes the city's oldest buildings, several museums, art galleries, and nightclubs, with Sarandi Street and the Mercado del Puerto being the most frequented venues of the old city. On the edge of Ciudad Vieja, Plaza Independencia is surrounded by many sights, including the Solis Theatre and the Palacio Salvo; the plaza also constitutes one end of 18 de Julio Avenue, the city's most important tourist destination outside of Ciudad Vieja. Apart from being a shopping street, the avenue is noted for its Art Deco buildings, three important public squares, the Gaucho Museum, the Palacio Municipal and many other sights. The avenue leads to the Obelisk of Montevideo; beyond that is Parque Batlle, which along with the Parque Prado is another important tourist destination. Along the coast, the Fortaleza del Cerro, the Rambla (the coastal avenue), 13 kilometres (8.1 mi) of sandy beaches, and Punta Gorda attract many tourists, as do the Barrio Sur and Palermo barrios.

SOLUTION:
What accounts for much of Uruguay's economy?
