HELLO BRAINLY USER
HERE IS YOUR ANSWER ___======_____==_____
Normal" SALINE used in Microbiology has the same osmolarity as most intra CELLULAR fluid. So when you ADD normal saline to suspend MICROORGANISMS in a specimen or culture, these microorganisms will not rupture due to either intracellular fluid coming out of the saline going in due to osmosis through the cell membrane.
