这是og12上一遍生物文章大概在128-133题之间,做题时感觉自己看懂了文章,但是对答案的时候发现,自己错了很多。令我比较困扰的是原文的这段:
Such a hierarchy may also exist in plants. Oligosac-
charins are fragments of the cell wall released by
enzymes: different enzymes release different oligosac-
charins. There are indications that pleiotropic plant
hormones may actually function by activating the
enzymes that release these other, more specific chemical
messengers from the cell wall
这段关系到了两道题,而且这两题我也错了····所以大侠们能不能帮忙翻译下最后那句话··实在困扰,特别是by后面的句子,实在看不懂阿···谢谢作者: taohuaxian 时间: 2010-6-21 06:52
