Vedclass · Answer

(A) The incorrect statement is that phosphorus is a constituent of all proteins. Phosphorus is a key component of cell membranes (phospholipids),nucleic acids ($DNA$ and $RNA$),and $ATP$,but it is not a constituent of all proteins. Proteins are primarily composed of amino acids containing carbon,hydrogen,oxygen,nitrogen,and sometimes sulfur. $Nitrosomonas$ and $Nitrobacter$ are indeed chemoautotrophs that oxidize ammonia and nitrite,respectively. $Anabaena$ and $Nostoc$ are cyanobacteria that fix atmospheric nitrogen while living freely. Root nodule-forming bacteria like $Rhizobium$ live as aerobes in the soil when they are not in a symbiotic association with legumes.
