Summary Introduction

To determine: The country that receives the least UV radiation.

Introduction: Different parts of the earth have variable exposure to UV radiations. The reflectance index is a measure of the amount of light energy especially UV radiations absorbed by the body per unit area. Melanosomes in skin synthesize melanin pigment and account for the human skin color. More melanin pigment provides protection against UV radiations and reflects less light.

Describe the relationship between melanin and UV light exposure in the human population. Include a description of both the effects of UV light on a person and function of melanin.
Consider the three types of human hair. Then, click and drag each label into the appropriate category. Labels → Drop Zones Reset All Male facial hair Terminal (1/3) Downy (2/3) Vellus (3/3) 90% of the hair on women Most of the hair on children except eyebrows, eyelashes, and scalp Armpit and pubic hair Eyebrows, eyelashes, and scalp Mostly found on a fetus Replaced by vellus Only 10% of hair on men
What is the only statement that correctly identifies the ability of different wavelengths of UV light to penetrate the human skin? Note: UVA is the longest wavelength (least energy), and UVC is the shortest wavelength (most energy). If you've studied the electromagnetic spectrum you may remember that wavelength and energy have an inverse relationship. We'll talk more about this later in the course. Group of answer choices A- UVA light penetrates  only as deep as the epidermis, which is where it has its effect   B-UVB light penetrates  only as deep as the epidermis, which is where it has its effect   C-UVC light penetrates  only as deep as the epidermis, which is where it has its effect
