某兴趣小组进行探究酵母菌细胞呼吸的方式活动经过提出问题和作出假设后设计了如图所示的实验组装了甲组和乙组两套实验装置．据图回答问题． 1两套实验装置中探讨酵母菌在有氧条件下细胞呼吸的是组探讨酵母菌在无氧条件下细胞呼吸的是组． 2甲组实验中空气通入a瓶酵母菌培养液之前要先通过Na0H溶液目的是要先除去空气中的． 3实验结果澄清的石灰水会变混浊的是组．本装置检测产物多少的依据是澄清的石灰水变混浊的． 4兴趣小组进一步检测呼吸作用的产物把a瓶和b瓶中酵母菌培养液的滤液注入酸性条件下的重铬酸钾进行检测结果瓶滤液变色而另一瓶没有颜色变化． 5本实验没有对照组而是设置了两个实验组通过对结果的比较分析来探究某种因素与实验对象的关系这样的实验叫做实验．
