If water has high latent heat of vaporization, how this property of water could be helpful to plants and animals?
Correct answer: D. With the release of small amount of water vapors, a great amount of heat loss can take place
- A. With the release of large amount of water vapors, a small amount of heat loss can take place
- B. No cooling effect with the release of even large amount of water vapors
- C. It will keep their temperature very high
- D. With the release of small amount of water vapors, a great amount of heat loss can take place
Explanation
Water absorbs much heat as it changes from liquid to gas and causes a cooling effect. Evaporation of only two ml out of one liter of water lowers the temperature of the remaining 998 ml by 1 °C.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
