一、对呼吸作用相关实验的考查例l图1是测量种子萌发时锥形瓶中气体体积变化的实验装置。锥形瓶中放的种子事先用水浸泡过并在稀释的消毒剂中清洗过(不影响种子生命力)。实验开始时U形管左侧与右侧液面相平,每隔半小时利用标尺量出右侧管内的图1液面高度变化,实验结果见表1。回答下列问题:
First, the examination example of the respiration-related experiments l Figure 1 is the experimental device to measure the change of gas volume in the conical flask when the seeds germinate. The seeds in the conical flask were soaked in water beforehand and washed in a diluted disinfectant (without affecting the vitality of the seeds). At the beginning of the experiment, the left side of the U-tube was flush with the liquid surface on the right side, and the height of the liquid surface in the right tube was measured using a ruler every half hour. The experimental results are shown in Table 1. Answer the following questions:
