The mitotic spindle is a structure that forms during cell division and separates duplicated chromosomes. In eukaryotic cells, the mitotic apparatus is composed of two centrosomes and spindle microtubules (Figure 43.9).The centrosome is 1–2 μm in diameter.Each centrosome is composed of two cenles of approximately 20 nm in diameter …

1. A SG apparatus measures the spin projection of electrons in a given axis (the one where the magnetic field is applied). For example, a SG in the z direction measures the probability of finding electons with spins in the up and down states in the z axis. Once your electrons pass through a SG device, their wave function collapse because of the ...

Distillation is a purification technique for a liquid or a mixture of liquids. We utilize the difference in boiling points of liquids as a basis of separation. The core of a distillation process, is selective evaporation and condensation of particular components. Our overall goal is to evaporate and condense only one component from a mixture ...

5: What was actually observed–atoms hit the detection screen in only two spots. Those clumping at the upper spot are said, as explained below, to have "spin up." Those clumping at the lower spot are said to have "spin down." Conclusion: The magnetism of silver atoms has only two states–north pole straight up or south pole straight up.
