How is the dark dorsal side and the light ventral side of a frog adaptive?

The advantages of different skin colours of the frog is in survival, they help them camouflage from predators. If a predator is below them, the brighter ventral site simulates the bright sky (or water surface). If the predator is above, then dorsal side helps the frog to blend into the surrounding ground environment (or floating vegetation). 

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
