实验1：将切除的胚芽鞘尖端放置于琼脂块上(图1)，移去尖端后，将琼脂切成体积相等的若干个方块，将方块放在除去尖端的胚芽鞘上，实验进行一定时间后，每个胚芽鞘弯曲的角度以图2的方法测量，并计算平均值。每次放在等面积、等体积琼脂块上的胚芽鞘尖端数量不同，这样重复上述过程。
实验2：用含有不同浓度IAA的琼脂块代替胚芽鞘尖端进一步实验。上述两个实验的结果如图3和图4所示。
（1）绘图表示，如何将琼脂块放置于胚芽鞘上，才能得到图3的结果?
（2）解释实验2的结果：IAA从0μmol/L～1.3μmol/L过程中 ；1.3μmol/L～1.8μmol/L过程中 。
（3）①比较实验1和实验2的结果有什么不同? 。
②为什么会出现这种不同？ 。
（4）从本实验可知促进胚芽鞘生长的最适生长素浓度约为_______
图4中曲线上b点对应生长素浓度时胚芽鞘弯曲角度为17度，把琼脂块去掉后，胚芽鞘最终会如何生长？________ 查看习题详情和答案>>
Later the boy lost his way in the street. When the mother found this, she went to look for him, but she couldn’t find him. Then she went to the police station to ask for help. She was very sad and didn’t know how to face her husband. After hearing the bad news, the father hurried to the police station. When he saw his wife, he didn’t blame(责备) her. Instead he said, “I love you, darling!”
“If I had picked him up or found this earlier, this would not have happened,” the father said to himself. He thought there was no point in blaming anyone. His wife also lost her only child. What he could give her was just understanding. Several weeks later, with the help of the police, they finally found their lost son. From then on, they became closer than before.
