You can only choose one category, so if in doubt, please choose the closest match.
PROBLEM: man angered Isabella de l'Anguileme when he named his brother as the Comte de Poitou. He won a battle against Henry III and the Comte de la Marche before negotiating a truce with Hugh of Lusignan at Taillebourg Bridge. John of Ibelin helped this man to push Fakhr ad-Din to Damietta in his most famous initiative, which later saw the arrival of Alfonso of Poitou at Cairo. He was captured at the Battle of Farsikur during a war that he fought alongside his brother, Robert of Artois. This son of Blanche of Castille and was the leader of the Seventh Crusade. For 10 points, name this ruler from 1226 to 1270, the only French king to be canonized.

SOLUTION: History

PROBLEM: proteins bind one end of these structures and help inhibit a process called "catastrophe. " These structures can have persistence lengths of 3-4 mm, which is several orders of magnitude higher than the average cellular diameter. These structures can be severed by katanin. Drugs such as paclitaxel stabilize these structures and prevent their depolymerization, where colchicine prevents its dimeric subunits from coming together. Shortening of these structure at the kinetochore ends of the spindle apparatus helps chromosomes walk towards poles during mitosis and meiosis. For 10 points, identify these structures which are components of the cytoskeleton and which are made of tubulin proteins.

SOLUTION: Science

PROBLEM: Debye was able to derive a formula for specific heat of a solid by summing their energies over the vibrational modes of the solid. Like photons, they obey Bose-Einstein statistics, and can thus be considered bosons. They play a central role in the BCS theory of superconductivity by interacting with electrons and connecting them in Cooper pairs. FTP, name these objects, the quanitized vibrations of an atomic lattice.
