Verified step by step guidance

Understand the concept of homeostasis: Homeostasis is the process by which living organisms regulate their internal environment to maintain a stable, constant condition, despite changes in the external environment.

Identify the key characteristics of homeostasis in vertebrates: Vertebrates have complex systems that help regulate factors such as temperature, pH, and ion concentrations to maintain equilibrium.

Evaluate the options given: Consider each statement and determine if it aligns with the concept of homeostasis. For example, maintaining a constant internal temperature is a form of homeostasis, but not all vertebrates maintain the same temperature.

Consider the diversity among vertebrates: Recognize that while all vertebrates regulate their internal environment, the specific mechanisms and conditions (like blood pressure and temperature) can vary widely among different species.

Conclude with the correct understanding: The statement 'They regulate their internal environment to maintain a stable, constant condition' is true for all adult vertebrates, as it aligns with the fundamental principle of homeostasis.
