📚 Conclusions and Discussion: Drawing Evidence-Based Conclusions in A-Level Biology | 结论与讨论：A-Level 生物中基于证据得出结论
In Cambridge International A-Level Biology, the conclusion and discussion section is where you demonstrate scientific thinking: answering the aim, judging whether the data support the hypothesis, explaining findings through biological mechanisms, and evaluating the strength of the evidence.
在剑桥国际A-Level生物中，结论与讨论部分是你展示科学思维的地方：回答实验目标、判断数据是否支持假设、通过生物学机制解释结果，并评估证据的强度。
1. What Examiners Expect from a Conclusion | 考官对结论的期望
A conclusion must be a clear statement that directly answers the aim or hypothesis. It should state the relationship between the independent and dependent variables, the direction of that relationship, and the key numerical support.
结论必须是一句明确陈述，直接回答实验目标或假设。它应说明自变量与因变量之间的关系、该关系的方向以及关键的数字依据。
For example, in an investigation of temperature and membrane permeability, avoid writing “the results were recorded”. Instead write: “As temperature increased from 20 °C to 60 °C, the absorbance of the surrounding solution increased from 0.12 to 0.68, showing that membrane permeability increased with temperature.”
例如，在研究温度与膜通透性的实验中，不要写“记录了结果”。而应写：“当温度从20 °C升高到60 °C时，周围溶液的吸光度从0.12增加到0.68，表明膜通透性随温度升高而增大。”
2. Distinguishing Results from Conclusions | 区分结果与结论
Results are the processed data, such as means, standard deviations or calculated rates. Conclusions are interpretations of those results in relation to the biological question.
结果是处理后的数据，如平均值、标准差或计算出的速率。结论是对这些结果在生物学问题中的解释。
