Question

which of the following best describes homeostasis?
the state of maintaining a stable internal environment despite changing external conditions
the state of maintaining a stable internal environment due to electrical impulses
the state of maintaining a stable internal environment due to chemical signals
the state of maintaining a stable internal environment when the external conditions are constant

Explanation:

La homeostasis es la capacidad de un organismo para mantener un entorno interno estable, independientemente de las condiciones externas cambiantes. Las opciones que mencionan impulsos eléctricos o señales químicas solo describen mecanismos parciales, no la definición general. Y la opción de condiciones externas constantes no es correcta, ya que la homeostasis se refiere precisamente a adaptarse a cambios externos.

Answer:

the state of maintaining a stable internal environment despite changing external conditions
