某生物兴趣小组的同学进行探究萘乙酸（NAA)促进插条生根最适浓度的预实验，结果如图所示。在预实验的基础上，他们又进一步设计如下实验探究萘乙酸促进生根的最适浓度。

（1)材料用具：生长旺盛的一年生月季枝条若干、烧杯、培养皿、量筒、NAA、蒸馏水等。（2)配制一系列具有浓度梯度的萘乙酸溶液5份，编号为1～5号。（3)实验步骤：第一步：将月季枝条随机均分为5等份；第二步：将5份枝条的基部分别浸泡在1～5号NAA溶液中：第三步：一天后，取出枝条分别进行扦插；第四步：每天对扦插的枝条生根情况进行观察记录。请回答相关问题：（1)配制的NAA溶液浓度应依次为_____（浓度梯度差为1.0μL/L)。（2)该实验中的自变量是____\__，因变量是________，同时要严格控制无关变量。（3)请设计本实验的观察记录表__________。（4)实验开始前进行预实验的意义是______。
