Question: These objects contain the zone of plastic flow and the zone of brittle flow. They are formed by compressing firn, and parts of them break off by calving. Till is soil left behind by these objects, which also push material to form moraines. Cirques (SERKS) and fjords (FYORDS) are among the landforms due to erosion by these objects. For 10 points, name these moving masses of land ice.

Answer: Science

Question: 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.

Answer: Science

Question: In some species, these bodies may be surrounded by segrosomes, and a convenient method of creating them is the LR/BP clonase gateway system. Some contain an addiction mechanism via the Hok/Sok factors, while another set are referred to as col. Alkaline lysis followed by column fractionation is one method of isolating them, while they may be introduced via cesium chloride, electroporation, or heat shock. Synthetic ones often contain a polylinker region and are extracted via the miniprep, and they were originally discovered by Joshua Lederberg in his studies of conjugation. Including the F-factor and R-factor, FTP, name these short, circular, extrachromosomal segments of DNA found in bacteria.
