Q: This structure does not function correctly in those with Stargardt disease, and certain cells in the capillaries of this structure can cause Scheerer's phenomenon. Muller glial cells found in this structure can dedifferentiate into multipotent progenitor cells, and Tay-Sachs disease is often diagnosed by a red spot on it. This structure receives oxygen from the choroid coat, which separates it from the (*) sclera. This structure's most sensitive region is the fovea, which is located at the center of its macula. Vitamin A is necessary for the function of this structure, which has a "blind spot" where it connects to the optical nerve. Rods and cones are found in, for ten points, which inner layer of the eye that sends optical signals to the brain

Q: One of his paintings appears to show a young boy looking at the viewer, holding up the decapitated head of a deer by its antlers. In addition to Putto with Hunting Trophy, this artist painted a now-lost Madonna of Albinea. He was commissioned by the abbess Giovanna Piacenza to paint numerous frescoes for a chamber in her convent, and he painted a fresco depicting a scene from the Book of Revelation on the ceiling of the San Giovanni Evangelista.

Q: Schwinger worked out a model of this operator by considering it as two uncoupled harmonic oscillators and showed that combinations of them satisfy the same commutation relations as this quantity. One theorem states that matrix elements of tensor operators in eigenstates of the operator of this quantity can be written as a coefficient term times a term independent of this quantity; that is the WignerEckart (*) theorem. The isotropy of space guarantees conservation of this quantity, and this quantity is the generator of rotations. Spherical harmonics are eigenstates of the operator of this quantity which is time integral of torque. For 10 points, name this quantity given by angular frequency times the moment of inertia, one type of which is spin.
