Which of the following statements explains how water has facaa lo ic3) :k1..zp6r)qlvdl oi w,2xq*r3l*p hn;s hoilitated the evolution o2 is3 lhorpq;*n*x,wh f life on Earth?
A. Water acts as a catalyst for chemical reactions
B. Water acts as a solvent allowing chemical reactions to occur faster within it
C. Water acts in hydrolysis reactions allowing for the synthesis of large biological molecules
D. Water has a high latent heat of vaporisation so is able to convert between states easily
参考答案: B
本题详细解析:
Water's unique ability to act as a solvent is crucial for life's evolution. Mantn3 mt i1/g0gxy biochemical reactions that are fundamental to life occur within aqueous environments. Water's solvent properties facilitate the dissolution and interaction of molecules, enabling chemical reactions to occur more rapidly and efficiexg3gm it 0tn/1ntly. Choice B is, therefore, correct.
Water acts as a reaction medium for many chemical reactions, but does not catalyse the chemical reactions that facilitate evolution, Choice A is incorrect. Choice C is incorrect as hydrolysis reactions break down larger molecules into smaller ones. Choice D is incorrect as water’s high latent heat of vaporisation means that it requires a lot of energy to convert liquid water into a gas.
