Explanation:
13. Some sunlight can be good as long as you have proper protection from overexposure. But too much ultraviolet, or UV, exposure can cause sunburn. The UV rays penetrate outer skin layers and hit the deeper layers of the skin, where they can damage or kill skin cells.
14. X-rays pass through most objects, including the body. ... Dense bone absorbs much of the radiation while soft tissue, such as muscle, fat and organs, allow more of the x-rays to pass through them. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray and air appears black.
15. Electromagnetic radiations also benefit other living things. Like plants for example, sunlight helps plants to produce chlorophyll in the process of photosynthesis.
