No, Polaris is always in the same spot in the sky.
The nucleus is not always in the center of the cell. It will be a big dark spot somewhere in the middle of all of the cytoplasm (cytosol). You probably won't find it near the edge of a cell because that might be a dangerous place for the nucleus to be.

If you are in the same place, the rainbow will always appear in the same place because it all has to do with the angle you are at in relation to the sun (42 degrees - see the related link). So if you are always in the same spot (e.g. at your desk at work), the sun will be coming from the same same angle, creating the rainbow in the same spot. My understanding of what I've read, you'll only see a rainbow in a certain place in the sky from the same spot at a certain time of the year because the sun moves depending on the season. Also, it is not only the angle of the sun but also the height of it that has to be the same.
Nucleolus
No, once it has a flat spot it will always have a flat spot. Replace the tire.
The red eye spot in a cell allows the cell to sense light so that it can move towards or away from it. The cell can swim by using the flagellum (long string like things on the end of a cell).Hope this helps :)

Yes. Every time the earth orbits the Sun it returns to the same spot
