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. the new species can tolerate small changes in this way, but dies from large changes because it has no mechanism for altering its own internal salt levels. what type of homeostatic mechanism is this species using to regulate its internal salt levels?
a) conformation
b) regulation
c) integration
d) assimilation
