According to the video “The Biology of Skin Color”, how does skin color throughout the world match up with UV exposure? A. Lighter skin is usually found in high UV areas while darker skin is usually found in low UV areas B. Skin color throughout the world does not match up with UV exposure C. Darker skin is usually found in high UV areas while lighter skin is usually found in low UV areas D. UV rays are the same throughout the world, so there is no pattern or correlation with skin color
