1交叉互换不等同于染色体变异。基因重组不改变基因的质,一般也不改变基因的量,染色体变异不改变基因的质,但会改变基因的量或改变基因的排列顺序

0今日推荐单词:contamination。pollution可以被替代的高级词,当然动词就是contaminate,跟pollute的用法完全一致,以此类推,污染物是pollutant,那么contaminate就要变成contaminant,但是contaminate还有另外一层意思指的是思想上的玷污,pollute反倒没这个意思,或者说用起来很怪,因为pollute大家基本上强调的是实际上的污染

0浆果与酵母,在晴风下热恋,酒窖中长眠。每一个年份都悠悠倾诉着往事,每一滴琼液都默默掩抑着情思。当年那颗落地的野葡萄,何曾想过这是一场盛大崇拜的开端,自天地间采撷甘醇,酿造风雨,品味时光;从实验里发掘生命,阐释机理,还原本真。酒,慰藉着历史,也冲破了科学的樊篱。

0读英语 真的浪费多少学生的脑力精力,还限制成 考研考博的条件,压制了 非精通英语的 人才! 现在的人工智能的翻译机,同声翻译,拍照翻译,完全足够正确翻译!英语真的是所有学生的讨厌科目,90%的学生,学了毕业后,对人生毫无用途! 考研,因为英语这垃圾,没考上,非常痛恨! 而同班的轻松考研究生的只是英语好,不见得头脑才能就好,明显偏向死记硬背能力面的多!广大莘莘学子深受中国式英语教育的摧残! 以后,可以将语文、数学

3有一个孤独的亲核试剂一直暗恋着一个碳原子。他希望有一天,这个碳原子会变成碳正离子,自己能够以SN1的机理去进攻她。可是他等啊等啊,却什么也没有发生。终于有一天,这个亲核试剂决定直接以SN2的机理向碳原子进攻。可是当他发现碳原子对于已经连在她上面的亲核基团有多么眷恋时,他不禁退却了。 时间一点一点地过去,这个亲核试剂始终无法忘记碳原子。可是他对自己的亲核能力没有信心——他既没有替代已经连着的基团的信心,也没

0分离定律的实质在我们学完伴性遗传以后那也就是书上三十页,有一个分离定律的实质和自由组合定律的实质,然后基因分离定律的实质指的是等位基因随着同源染色体的分开而分离这个动作就是基因分离,那等位基因会分开是在减数分裂的时候,减数分裂的结果是产生配子,那么基因分离定律的实质最后体现在形成配子的这个过程中。基因分离定律的实质是Aa的生物能够产生A和a的配子比例为1:1。那么自由组合定律的实质AaBb的生物个体能够产生ABAbaBa

0电场力不做功,电势能等于0,根据定义该点的电势等于0,孤立的带电体,虽然是等势体,但是电势不等于0,导体是外表面才是等势体,内部有感应电荷,感应电荷会产生一个新的感应电场,和外电场叠加之后变为0,如果叠加不为0,肯定还有新的感应电荷产生,所以最终都会平衡,导体内部合场强就是0,这需要一定的时间来完成,不过由于电子移动速度很快,所以忽略这个内部电场的时间
