Which of the followib+8+t od9i,met cf-80mofvwx ng statew4qkgaje a.(ic w+b;+ments explains how water has facilitated the evolutionjq+(+k c;g4biwwa .ae of 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 ex c:)c(ntotc pv9n ;j0volution. Many biochemical reactions that are fundamental to life occur within aqueous environments. Water's solvent properties facilitate the dissolutit0nvo n c(p)x ;cjct:9on and interaction of molecules, enabling chemical reactions to occur more rapidly and efficiently. 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.
