(1)请完善下面的实验设计,探究“苍蝇搓‘脚’是为了清除脚上的污物”.
材料用具:两个透明的干净玻璃瓶、若干只活苍蝇
实验思路:①在甲(瓶内无污物)、乙(瓶内有污物)两个玻璃瓶中,分别放入数量_____的活苍蝇;并进行观察和记录(如图).
②在同一时间内观察记录甲、乙两个玻璃瓶中_____的次数.
③可能的实验结果和实验结论:
若_____,则说明苍蝇搓‘脚’与清除‘脚’上的污物无关.
若_____,则说明苍蝇搓‘脚’与清除‘脚’上的污物有关.
(2)此实验的变量是_____.

二是繁殖能力强.理论上一只雌蛾一年繁殖幼虫可达O.3﹣﹣2亿只.
三是传播途径广.幼虫、蛹、成虫可通过人流、物流、交通运输等进行远距离传播.
材料二:自2008年9月份,江北水城爆发美国白蛾灾情以来,全民动员,对第一、二、三代美国白蛾采取灯光诱杀、AY﹣剪除网幕、挖蛹、捕捉幼虫、打药、释放用氏啮小蜂等方法进行化学、物理、生物方法防治.

(1)由A控制的性状叫_____,由a控制的性状叫_____,他们是一对_____,是通过_____产生的。
(2)父亲的基因型是_____,母亲的基因型是_____,孩子丁的基因型是_____。
(3)父亲能产生_____种精子,其基因型是_____,母亲能产生_____种卵细胞,其基因型是_____。
(4)受精卵可能具有的基因型是_____种。
(5)这对夫妇所生的孩子患白化病的可能性为_____%.如果再生一个孩子是男孩的可能性为_____%。

(1)这种控制虫害的方法属于_____,具有_____的特点。
(2)如图是松毛虫个体发育中两个阶段的图片,请据图说出它的个体发育属于_____;甲图表示的是_____阶段。
(3)松毛虫的体细胞中染色体数为68条,则其卵细胞的染色体数目为_____。
