What describes the ability of cell to communicate with each other in biofilms? - CORRECT ANSWER -quorum sensing
Through quorum sensing, an _____ is produced to regulate specific genes and lets the bacterial cell monitor the cell population density. - CORRECT ANSWER -autoinducer
A signaling molecule that monitors quorum sensing is a ____ ____. - CORRECT ANSWER -homoserine lactone
Red algae will produce ____ which block the homoserine lactone signaling molecules, to stop exopolysaccharide synthesis. - CORRECT ANSWER -Furanones
This is secreted in quorum sensing that makes it highly resistant.
- CORRECT ANSWER -exopolysaccharide 1 / 4
