Skin color is indeed related to UV radiation. In the equator, there is higher UV radiation due to the tropical climate in the equator. The equator is at 0 to 20 latitude therefore at this location, darker skin are found because darker skin helps protect from sun damage. From the temperate regions at 60 to 80 latitude, lighter skin is found as UV rays are not as potent compared to the equator.
<em>The correct answer is dark skin at 0-20 and light skin at 60-80.</em>

Explanation:
Both organelles, the mitochondria and chloroplasts (in photosynthetic organisms), are compartments that are believed to be of endosymbiotic origin.A compartment is a separate space within a larger whole. In relationship to the endomembrane system and the nucleus.organelles that aren’t part of the endomembrane system, such as mitochondria and chloroplasts.Cellular compartmentalization allows cells to optimize the efficiency of the processes that occur within organelles. But despite the advantages of compartmentalization, it’s not a universal feature of life. In fact, compartmentalization of cellular functions into membrane-bound organelles is limited to only one of life’s three major groups, or domains. That domain is the one that we belong to, the Eukarya. In addition to animals, eukarya includes plants, fungi, and other organisms with eukaryotic cells: cells that are relatively large, complex, and compartmentalized. And to see why that is, we need to look at how life has diverged over time.
