Regulating your body temperature is a part of maintaining homeostasis. Which part of a person's diet plays the largest role in regulating body temperature? A. Minerals B. Iron C. Vitamins D. Water

The correct option is D.

Explanation:

Water help to maintain homeostasis or regulate body temperature because water has the ability to maintain internal body temperature by responding to the body external temperature. The mechanism water uses to regulate temperature is sweat. When the external temperature is high , sweat. Help to prevent the body from overheating and this water is loss by evaporation and after that there is cooling which regulate the temperature.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
