are highly sensitive to antibiotics. have a glycocalyx. produce catalase enzyme. produce hemolysins. can grow in the presence of bile salts.Explanation / Answer
ANSWER 1) d. a biofilm
Inferences: Mycoplasma Pneumoniae form biofilm that protects it from being killed by the outer host immunity and antimicrobials. At low temperature, the survival of the organism is solely a function of RH with a survival pattern unique to the organism involved. Hypertonic environmentM.Pneumoniae can grow in osmotically stable environment. Isotonic solution have an equal osmotic stability like in human host but in human the osmotic pressure may be subjected to changes which may risk the survive of the organism.
