[EX Q]: In topological insulators, one version of this effect gives rise to a defect-resistant current induced by spin-orbit coupling. In graphene, this effect is shifted by one half, giving rise to an anomalous minimum of the relevant quantity, which can allow for ballistic transport. A more complex version of it was discovered in gallium arsenide and can be explained by Laughlin quasiparticles; this is referred to as the fractional version. This effect can be understood in terms of partial filling of Landau levels and has characteristic "plateaus", and it yields numbers called filling factors. Discovered by Klaus von Klitzing when studying a two-dimensional electron gas, for 10 points, identify this effect in which conductivity in a strong magnetic field is quantized.

[EX Q]: This organelle's lamina helps support its shape. Some protists have both a macro and micro version of this organelle. One part of this organelle is the location of ribosome synthesis, while importins and exportins assist in transport in and out of this organelle. This organelle, whose envelope is continuous with the rough endoplasmic reticulum, has pores in its double membrane. Transcription occurs within this organelle, which disappears during mitosis as its chromatin assemble into chromosomes. For 10 points, name the control center of the cell.

[EX Q]: One of this religion's texts follows the seeker through places named for Search, Knowledge, and Wonderment, before arriving in the "Valley of True Poverty and Absolute Nothingness. " Along with The Gems of Divine Mysteries, that work, The Seven Valleys, was written by this religion's founder. After the death of this religion's Guardian, its Hands of the Cause announced the election of its ruling body, the Universal House of Justice. Haifa is the site of the tomb of one of its holy men, the Bb. Its texts include the Most Holy Book and the Book of Certitude.
