Question: 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.

Answer: Science


Question: A quantity analogous to this effect in electrodynamics is called the Christofel voltage, while large motions restored by it were found by Carl Rossby. The Etvs effect accounts for its vertical component, and Buys-Ballot's Law is a result of this effect in areas of different pressure. Present only in non-inertial frames of reference, this effect was also considered when Laplace derived his tidal equations, and it influences the rotation of sunspots and the circulation of the atmosphere. Proportional to the cross product of the angular frequency and velocity, this is, FTP, which force that describes the tendency of a body to drift away from its course due to the Earth's rotation

Answer: Science
