Human skin color is a polygenic trait, which means that multiple gene loci (with different alleles) are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues. Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).

Wind is caused by which of the following?
Paraphin [41]
C. The uneven heated of Earth's different surfaces. For e.g., land changes temperatures quicker as compared to the sea.

When the sun comes up, the land heats up quicker than the sea. As a result, air above the land will also heat up more than air above the sea. As hotter air rises from the land, the cooler air travels to the space which the hotter air rose from. This creates wind, or a cycle of air currents.

Hope this helps! :)

P.S. By the way, this seems to be more so of Geography as compared to Biology. :) No worries though!

                ↓

             Snakes

                ↓

              Eagles

Answer B:

The animals in the second trophic level are prey to the animal of the third trophic level. The energy which is stored in the rabbits will be received by the snakes of the third trophic level when a snake will consume a rabbit. However, only 10% of the energy will pass from the rabbits to the snakes.
