Answer:
Black fur is more fit to survive in the environment than other colors of fur.
Explanation:
"Fitness", in terms of natural selection, is an organism's likelihood to survive in a given environment. Assuming that the increase in black fur is significant (Not attributable to pure chance), we can safely assume this is because Black Fur provides a competitive advantage in said environment over other colors of fur. There may be black terrain that allows them to blend into the environment and ovoid predators, or maybe it keeps them warmer if it is located in a cold region, thereby reducing the amount of resources they need to spend to stay warm.

Explanation:
Cytokinesis is the process by which the cytoplasm splits, forming two daughter cells from one parental cell. It occurs towards the end of mitosis, after the DNA has been replicated. The process of mitosis generates a cell with two nuclei, and cytokinesis ensures that each daughter cell receives one nucleus.
Without the process of cytokinesis, the physical process of the production of two cells from one parental cell would not occur, so the cell would not divide into two daughter cells.
Nitrogen is the most important component of DNA, protein, enzymes etc. Its recycling in the atmosphere is necessary, beacuse free nitrogen in the atmosphere balance the atmosphere composition. In soil it is important for fertility needed for plant growth. In heterotrophs it is an essential component of organic compounds.
