John went to bed after he finished his homework.还能怎么转换 转录因子是什么?其与DNA结合的功能域（motif）的结构特点是什么? 转录因子具有独立的DNA结合和转录激活结构域 对么? 请问哪里有卖硫黄啊是那种实验用的固体硫磺 蛋白质的哪些结构域可以结合锌离子, 硫和硫黄有什么区别?硫和硫黄到底有什么区别? 在观察植物细胞的有丝分裂试验中,对根尖染色的目的是使什么着色 如何在NCBI上预测以蛋白质的结构域 But the family is always f.of fun. you can not imagine what fun it is to swim in the sea with my family 中为什么用 what fun It is fun to go camping and lie in a warm__by the camping fire for the night.根据句意填空 making all the camping activities a family activity 帮忙解析下这个句子 Mr.li is very_(fun)._(listen)to him is fun she does after-school _____(activity)after workthese bags are those _____(run) 急外语filter-->brush strocks--->spatter这是PS软件里的 Photoshop中【Filter】→【Render】→【3D Transform】对应中文的什么命令? PS如何使用3D功能我的是CS6的扩展版本,所以是应该可以使用3D的,但是按3D的时候是灰色的,会跳出下面这个框框,我按里面说的看了,但是我原来就是设置好可以使用图形处理器的,我想问现在不 谁知道这种人脑构造图怎么做 人脑构造原理人脑控制思维区域的构造是什么 怎么控制 人脑中有哪些中枢结构 人脑记忆的结构基础到底是什么电脑储存的结构基础是磁结构,那人脑呢,不会真的像刺客信条一样都能保留在DNAl里吧.电脑储存使用二进制是方便,那人呢,为什么也会是二进制呢 They had a pleasant chat_____a cup of tea.A.for B.with C.over D.during Yesterday we had a pleasant chat__a cup of tea.A.over B.during C.in D.within Which to choose?And why? 12.We had a pleasant chat ______ a cup of tea.A.for B.with C.during D.over 13.I can hardly get asleep______ the noise outside so loud.A.as B.for C.with D.because 为何选DC They had a pleasant chat ______ a cup of coffee.A.forB.withC.duringD.over【要理由。】 电感线圈对交变电流的阻碍作用是由线圈电阻产生的 they had a pleasant chat during a cup of coffee与 they had a pleasant chat over a cup of coffee 有什么区别? 线型结构、支化结构和交联结构的高分子性能有什么不同?
