question:
This molecule facilitates the Griesbaum reaction and cleaves an alkene to forms an aldehyde or a ketone in a 1,3 dipolar cycloaddition, the Criegee mechanism. In the Chapman Cycle, this diamagnetic compound with a bent geometry is replenished by a paramagnetic, diatomic molecule. In that reaction, this molecule is formed by the absorption of a photon with a wavelength of less than 280 nanometers. It can be depleted by chlorofluorocarbons, making the Earth more susceptible to ultraviolet radiation. For 10 points, name this molecule found in a namesake atmospheric "layer", a triatomic allotrope of oxygen.
answer:
Science


question:
This compound promotes the dephosphorylation and activation of enzyme HMG-CoA to favor cholesterol synthesis and a phenylalanine for leucine substitution at residue B25 results in its "Chicago" variety. Its biosynthesis involves an excision of the C-peptide, and the compound functions by binding to tyrosine kinase receptors on cell surfaces. Sanger's improvement upon the methods of Edman degradation involved its sequencing, and its production occurs primarily in beta cells on the islets of langerhans. For ten points, name this pancreatic counterpart of glucagon used to regulate blood sugar, deficiencies of which are found in sufferers of diabetes.  
answer:
Science


question:
He ousted Ilyas-Khoja and Tughlugh, the Jagataite khans of the Ili River region. A duumvirate formed with his brother-in-law, Mir Husain, proved short-lived, as he assassinated Husain after besieging the city of Balkh to secure his control over the rebellious Afghans. Successive victories followed over Mogholistan, the Kipchak khanate, and the Egyptian Mamlukes. After capturing the Ottoman sultan Bayezid the Lightning-bolt at Ankara, he massacred the Knights of Rhodes at Smyrna. Vowing to undertake the conquest and conversion to Islam of Ming China, he died of disease near Otrar before his departure. FTP, name this Central Asian leader, whose warlike exploits inspired a blank verse drama by Christopher Marlowe.
