Secondary: local regions of polypeptide chain fold into specific shapes (shapes arise from the bonding forces between amino acids close in proximity of linear sequence…
If the polypeptide chain form beta pleated sheets (folded chains running parallel to each other) then the hydrogen bonds between the CO (carboxyl group) and NH (amino group) occurs between two separate beta pleated polypeptide chains (see figure 10)…

But Niels Bohr looked into this and found out that electrons move in paths around the nucleus. Surprisingly these electron can move from one path to another. They can also jump to a path that is a level above. Bohr created a model called the planetary model. This model shows how the electron move in different energy levels.…

The origin of earth’s magnetic field is a result of molten metal in the outer core that circulates around the inner core like a giant dynamo. Magnetism of the lithosphere supports the model of plate tectonics through the development of new oceanic crust that formed volcanism at the ridge crest in the prevailing polarity. This new crust was split apart and then moved in opposite directions. This explains new lithosphere at mid oceanic plate margins.…

Evidence of crossing over can often be seen under the light microscope as an X-shaped structure known as ________.…
7) Astronomers detect the presence of a magnetic field in hot gasses such as the field in the solar photosphere by observing the Zeeman effect. This is the splitting of spectral lines when a magnetic field is present. It can be observed from the sun by focusing a spectroscope on light coming from a sunspot.…
