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:
This force is represented by a first derivative with respect to position in the harmonic oscillator equation. In one model, this force stems from tiny electrostatic repulsions. It can be understood as the parallel shear component of the contact force, whose other component is typically calculated as mg cosine theta. It is calculated from a coefficient, symbolized mu, multiplied by the normal force. Rolling motion is affected by the "kinetic" type of this force, which is known as "drag" in fluids. For 10 points, name this force that resists the motion of objects against one another.
answer:
Science


question:
In reproductions of this work, the image of a woman screaming towards the sky is often excluded. In 1974, this painting was defaced with red spray paint and the words KILL LIES ALL. Commissioned for the 1937 World's Fair in Paris, this black and white work depicts a man trying to steal a baby from its mother, Lady Liberty carrying the lamp of democracy, a flower growing from a shattered vase, and a horse drowning in chaos. FTP, name anti-war Pablo Picasso painting named for a bombed Basque city.
