- Why might bacteria use quorum sensing to regulate genes needed for virulence? How might this reason be related to the rationale behind using quorum sensing to establish a symbiotic relationship?In a population of cyanobacteria (Chlorogloeopsis fritschii) in a hot spring in Iceland, some of the bacteria can produce chlorophyll f, while some C. fritschii produce only other types of chlorophylls. Chlorophyll f absorbs light outside of the visible light spectrum, namely near infrared light, allowing the bacteria to absorb light that has not been absorbed or reflected by the water or other organisms. The ability to produce chlorophyll f is heritable, and the bacteria with chlorophyll f can live in low-light environments, such as underneath other organisms, or near the bottom of the light-penetrating zone of the spring. What is the adaptation in this population of C. fritschii living in low-light environments? (Choose one.) a) the ability to produce chlorophyll f b) the ability to produce any type of chlorophyll c) the ability to tolerate the high temperatures of the hot spring d) the ability to survive and reproduceWith respect to F+ and F- bacterial matings, (a) How was it established that physical contact was necessary? (b) How was it established that chromosome transfer was unidirectional? (c) What is the genetic basis of a bacterium being F+?
