Answer:
c. Spindle fibers
Explanation:
In eukaryotic cells, the centrioles are small sets of microtubules composed of tubulin proteins. Moreover, in animal cells, a centrosome is an organelle localized near the nucleus which contains a pair of centrioles. These organelles (centrosomes) are referred to as microtubule-organizing centers. During Anaphase, centrioles move to opposite sides in the cell in order to organize the spindle fibers and separate the chromosomes during cell division.

If the first coat color is black for example, the mice will be able to hide away in a dark area or corner, they will also be able to move around at night almost undetected. Changes in environment, such as development and introduction of street lighting may cause these mice to be easily seen by predators. These mice will quickly be eaten by predators now that they are accessible. On the other hand mice that have a different color such as white or grey will be able to blend in better with the new surroundings. These mice will pass along this trait to their progeny and the new coat color will proliferate.
<span>UV radiation has a penetration power that can go down to the dermis, when UVA, or to the deepest layer of the epidermis, when UVB. UVA and UVB are the type of radiation that's the most potentially dangerous for DNA damaging to happen. Melanin absorbs the UV rays reducing the damage that these may produce to the living cells of the dermis and deeper, just bellow these granules.</span>
