Practice questions

1 of 45Practice questions for this set
Researchers isolated two bacterial strains from a hypersaline lake. Both strains grew well at 3.5 M NaCl, but only Strain H remained viable after rapid transfer to freshwater. Chemical analysis showed Strain H produced a thick extracellular polysaccharide layer and formed compact cell aggregates. When a gene required for polysaccharide export was knocked out, the mutant lost freshwater survival despite unchanged intracellular enzyme profiles. Which evolutionary adaptation would be expected given the described conditions and results?
