在选择题中有时遇到应激性和适应性两个供选答案同时并存的情形，对应激性和适应性现象的辨别是概念复习中的一个难点。下面就辨别方法谈谈看法。首先，应激性是指生物体随着变化的刺激而发生相应反应的能力或特性．适应性是指机体随着变化的环境而发生相应的机能和结构变化， In the multiple-choice questions, it is sometimes encountered that two stressors and adaptive answers coexist at the same time. The identification of stress and adaptive phenomena is a difficult point in the conceptual review. Let’s talk about the methods of discrimination. First of all, stress refers to the ability or characteristics of organisms to respond accordingly to changing stimuli. Adaptability means that the body undergoes corresponding changes in function and structure with the changing environment.
