A. When the salt concentration of the fluid on the airway surfaces of healthy people is raised artificially, the salt concentration soon returns to normal. 盐度被人为提高后悔回复到正常态
B.A sample of the antibiotic was capable of killing bacteria in an environment with an unusually low concentration of salt. 抗生素在低盐度下可以正常杀菌——和盐度高导致不能杀菌没有关系,因为不能证明抗生素在高盐度下不能杀菌。
C.When lung tissue from people with cystic fibrosis is maintained in a solution with a normal salt concentration, the tissue can resist bacteria. 有CF的肝组织在正常盐度下可以杀菌.
我晕死,我怎么在做题的时候就没有注意到那个“with cystic fibrosis”呢………………
