如图所示,甲是探究“动能的大小与什么因素有关”的实验装置,实验中让同一钢球从斜面上不同的高度由静止滚下,碰到同一木块上.乙是探究“阻力对物体运动的影响”的实验装置,实验中让同一小车从斜面上相同的高度由静止滑下,在粗糙程度不同的水平面上运动.请回答下列问题:

  (1)甲实验的目的是探究钢球动能的大小与             的关系;实验时,它是通过观察            ,从而判断钢球动能的大小。
  (2)进行乙实验时,每一次都让同一小车从斜面上相同的高度由静止滑下,其目的是使小车在水平面运动的起始             相同;通过观察小车在粗糙程度不同的水平面上运动            来判断小车在不同的水平面受到            的大小.从而可以推理:如果运动的物体不受力,它将                。

明同学利用A、B两物体、砝码、泡沫等器材探究“压力的作用效果与什么因素有关”的实验.如图

(1)实验中,小明是通过观察   ▲   来比较压力作用效果的.
(2)比较甲、乙两图所示实验,能够得到的结论是:       ▲     
(3)若要探究“压力的作用效果与受力面积大小的关系”,应通过比较图   ▲  
所示实验.
(4)小华同学实验时将物体B沿竖直方向切成大小不同的两块,如图丁所示.他发现
它们对泡沫的压力作用效果相同,由此他得出的结论是:压力作用效果与受力面积无关.你认为他在探究过程中存在的问题是:          ▲            .

如图为人体部分特异性免疫过程的示意图,a、b、c表示细胞。请据图回答下列问题。

(1)该特异性免疫属于       免疫,图中b细胞在人体内可以来自                   细胞。
(2)图中a、b、c、d能够识别抗原的是         。(填字母)
(3)若图中所示的抗原为酿脓链球菌,因其表面的抗原决定簇与人心脏瓣膜上的一种物质的表面结构十分相似,物质d向心脏瓣膜发起进攻,使人患上风湿性心脏病,这属于免疫失调中的             病。
(4)当抗原经过⑤⑥过程时,人体内产生d的主要特点是数量多、速度快,与合成与分泌d有关的细胞器有           、           、
           、           。
(5)研究发现,HIV病毒的增殖需要逆转录酶,从遗传物质分析,研究HIV疫苗比较困难的主要原因是                                                          。
