Streptococcus pneumoniae is a bacterial pathogen that can cause pneumonia. laboratory studies of various subtypes of this organism by the rockefeller university scientists revealed that some of them produced colonies of different opacity (cloudiness). they found that compared with bacteria from opaque colonies, bacteria from more transparent colonies were found to grow more quickly and to adhere more efficiently to bronchial cells in culture. they also found that the bacteria from transparent colonies contained a phage strain called mm1-1998. based on this information, which of the following statements are true?
s. pneumoniae forming transparent colonies are lysogens.
s. pneumoniae bacteria containing mm1-1998 have a competitive advantage.
providing that the culture conditions of the s. pneumoniae are unchanged, subsequent generations of this bacterium will also exhibit change in transparency and growth ability.
