If body temperature is too high some blood vessels increase in size and sweat glands will excrete sweat resulting in a lower body temperature these changes are an example of

The answer is -Homeostasis

The human body has the ability to maintain a constant internal environment so that every organ function properly. Maintenance of a constant internal conditions is called homeostasis. For examples, a healthy human body functions optimum at normal temperature which is 37°C. If the body temperature increases well above 37°C, then by self-regulatory process, our  body brings down temperature to the normal. This is homeostasis.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

explanation:

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.
