在完成了观察洋葱根尖分生区细胞有丝分裂实验后，教师给学生提供了2份资料。

资料一：一份“实验报告”的部分内容

(一)解离：剪取洋葱根尖5cm，放入盛有质量分数为15%的盐酸和体积分数为95%的酒精混合液(体积比为1:1)的玻璃皿中，在室温下解离3～5min。

(二)染色：把根尖放在盛有0.01g/mL龙胆紫溶液的玻璃皿中染色3～5cm。

(三)漂洗：将根尖放入盛有清水的玻璃皿中漂洗约10min。

(四)制片：将根尖放在载玻片上，加一滴清水，并用镊子把根尖弄碎，盖上载玻片，用拇指轻轻按压载坡片……

资料二：全班20个实验小组的实验数据汇总表(注：各小组计数50个细胞，实验条件与观察计数方法相同)

(1)请改正“资料一”中的3处错误：_________________，__________________，___________________。

(2)若已知洋葱根尖分生区细胞的细胞周期为12.0h，请根据“资料二”，在下图的圆中用扇形图表示出间期、前期、中期以及后期和末期所占的时间(单位：h，精确到小数点后一位)。

(3)有些因素会影响细胞周期各时期的长短，实验过程中也会产生一些误差。因而对整个实验结果可能产生影响的有___________。

①取材时间 ②根尖培养温度 ③解离时间长短 ④载玻片厚度 ⑤计数的细胞是否属于分生区细胞 ⑥细胞周期各时期区分是否准确
