Question
Chapter 2, Problem 5RQ
Summary Introduction
To explain:
The reason why water absorbs a great amount of heat with little increases in its temperature and also determines the name of this property of water.
Introduction:
Water is transparent chemical substances that lack taste, color or odor. They are polar molecules and have a tendency to form a hydrogen bond.

Which of the following are properties of water that make itimportant for living cells?(a) It is a polar molecule that can form solutions.(b) It has high surface tension.(c) It has a high specific heat.(d) It can participate in dehydration and hydrolysisreactions.(e) All of the above.
Despite the thermal stability of covalent bonds in physiological systems, some of these bonds are sensitive to energy input from external sources. The molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. If the increase in energy is above kT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state. Which one of the following physiological process is example to this?
Select one :
a. Absorbance of light by 11-cis-retinal.
b. Translucent to opaque conversion of egg whites after cooking.
C. Absorbance of light by melanın.
d. a & b
e. a & c
f.b&c
