Answer:

sry if im wrong) Coal and natural gas were the most used energy fuels for generating electricity. The world's electricity consumption was 18,608 TWh in 2012. ... In 2016 the total world energy came from 80% fossil fuels, 10% biofuels, 5% nuclear, and 5% renewable (hydro, wind, solar, geothermal).

Answer:

  1. Respiratory system
  2. Nervous system
  3. Circulatory system
  4. Integumentary system
  5. Endocrine system

Explanation:

During excessive hard work or sports, the respiratory system acts to provide sufficient oxygen for energy supply (ATP) - a process takes place in mitochondria. At the very beginning, the respiratory system is active. If the person doesn't intake sufficient water, he will feel tired because of heavy breathing that increases body temperature and affects metabolic reactions. A supply of water would help decrease the respiration need and so support other systems.

The nervous system (hypothalamus) regulates the body temperature which is necessary for metabolic reactions taking place within the body, i.e. homeostasis. During and after exercise, the water intake was not sufficient, this means that the hypothalamus would work to maintain the temperature as well as other metabolic mechanisms. In the case of less water intake, the nervous system would be in stress.

The circulatory system acts to transport blood and oxygen to all parts of the body. During sports activities, the oxygen supply would be high to maintain energy supply. This takes place with the combined action of the circulatory system and respiratory system. For optimal functioning, the circulatory system needs fluids (water) intake because sufficient water is already lost during sports.

The integumentary system is the system that directly protects the body from damages including dehydration. Therefore, in this case, it will be highly active.

The endocrine system consists of glands that produce hormones to control body metabolism. The body metabolism, as mentioned before, is driven through water availability. The reduced water in the body would also put the endocrine system under pressure.

Answer: Light Refraction

Explanation:

Light rays travel in straight lines. When they strike an opaque surface, the rays bounce, and light is reflected back to your eye so that you see an image. When light strikes a transparent object, some of the light passes through. If that light strikes the object straight on, it continues to travel in a straight line. If the light enters the transparent object at an angle, though, it changes direction, bending.This bending of light is called refraction. Refraction occurs because light entering an object slows down. When it enters at an angle, one side of the light ray enters before the other, slowing down first.Looking from above, an object under water appears larger than it does in air. It's not that the image the light gave our eyes is bigger. It's that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water's surface. Light passing straight down would be perpendicular to the water's surface, like the vertical line on the letter T.
