Q: Coombs tests detect these bodies bound to erythrocytes, and a technique that uses these entities is ELISA. These molecules have a namesake fold, in which two beta sheets are held together by amino acid charges. These adaptable molecules can somatically recombine in a process called V(D)J recombination and are also capable of changing isotype by altering conformation of their heavy chains. Like enzymes, they operate via a a so-called "lock-and-key" mechanism, as verified by Linus Pauling. FTP, name these characteristically y-shaped immune molecules exploited in vaccination and produced by B cells in response to specific antigens.

Q: This rule holds if the operator algebra for some set of observables is non-trivial; that is true because it is derived via the Schwarz inequality applied to the expectation value of the commutator of two observables operators. It formally bounds the product of the dispersions in two observables. An adapted form of this law applies to energy and time; it applies directly to any two components of spin, but it is best known in its application to position and momentum, the product of the standard deviations of which is at least h-bar over two. FTP, name this principle from quantum mechanics that limits the precision of measurements.

Q: In the introduction to the second edition of this work, the author described how Hubert Humphrey won a 1948 Senate race over a man who championed the ideas of Jeremy Bentham. It criticizes the inability of monetary policy to have any influence on wage-price interactions in a chapter called The Monetary Illusion, while chapter 11 of this work criticizes consumer wants which arise from the process of satisfying wants and calls it the dependence effect. Another chapter criticizes the use of GDP and GNP as a measure of quality of life and is titled The Paramount Position of Production. Its author originally titled it Why the Poor are Poor and discarded another title which described the central entity as opulent and its second chapter contains an attack on a concept which espouses predictability over originality and preaches what the audience most wants to hear, conventional wisdom. For 10 points, identify this magnum opus of John Kenneth Galbraith.
