How do you know that homeostasis was achieved?

Homeostasis is achieved when an organism maintains stable internal conditions despite external changes. This can be observed through physiological indicators such as consistent body temperature, balanced pH levels, and stable glucose concentrations. Additionally, behavioral responses, such as seeking shade when hot or drinking water when dehydrated, can indicate that the body is actively regulating its internal environment to maintain homeostasis. Overall, homeostasis is confirmed when these internal parameters remain within a narrow, optimal range.
