You discover a new species of bacteria that grows in aquatic environments with high salt levels. While studying these bacteria, you note that their internal environment is similar to the salt concentrations in their surroundings
You also discover that the internal salt concentrations of the bacteria change as the salt concentration in their environment changes.
