Because of the large heat of __________ of water, the evaporation from a liquid surface is a very effective cooling mechanism. T
he human body makes use of evaporative cooling by __________ to give off energy even when surrounded by a temperature higher than body temperature. A) fusion; transpiration B) vaporization; shivering C) sublimation; perspiration D) vaporization; perspiration
vaporization; perspiration. Water has a high specific heat capacity due to its polarity. It therefore also has a high heat of vaporization: the energy required to turn liquid water (sweat) into a gas.
The four bases in DNA are: adenine, thymine, cytosine, guanine. In RNA, thymine gets replaced by uracil. Purine is only a name for the two bases guanine and adenine.
