Which of the following r5l 2fxuhq -jp0u5)ov statements explains how water tghplm)r6:0 mv.7na p0hzr w7 has facilitated the evolution of life on Earth? rla )7rz0m:h6.0pptw7mvghn
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 abilit 1(rhf9gx ndkkl( ,y0uqsb-ib07 v 6eby to act as a solvent is crucial for life's evolution. Manyb70sd ql i6 -y(n x1u(ebk r0,fhvbk9g 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 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.
