试题来源: 解析 C。解析:在化学里,氯化钠(sodium chloride)是电解质,其水溶液能导电。而糖(sugar)和乙醇(ethanol)是非电解质,它们的水溶液不导电,油(oil)也不导电。这里“conductor”是导体的意思,“aqueous solution”表示水溶液,这些词汇准确描述了化学中的导电性质相关概念。

in the English language. Aluminum is used widely in North America, while aluminium is accepted everywhere else in the world. The history of this difference dates back to the 19th century when a scientist renamed the element to match other elements in the periodic table (potassium, sodium, etc...
ERBB3 show several similarities to ALK, encoding the NB familial gene [25], and thus made a good candidate gene with potential role in the tumour development of r4 tumour types. Among the down-regulated genes in the r4 subgroup CACNA2D3 was the most significant in comparison to the r1 ...
