Answer 1

Answer:

Dog drinking water after it feels thirsty is an example of an organism responding to its internal environment to maintain homeostasis.

Explanation:

The regulation of temperature of the body of an organism is called homeostasis. Warm blooded organisms depend on their internal environment to maintain homeostasis while cold blooded organisms completely depend on their external environment to maintain homeostasis.

The body temperatures of warm blooded organisms maintain its constancy despite changing temperature of the external environment.  But the case of cold blooded organisms is different.

Their body temperature completely depends on the external environment and thus they have several behavioral and physiological adaptations to maintain their body temperatures at the comfortable level.

In this example dog is a warm blooded animal and it drinks water to maintain homeostasis since water helps in thermal regulation of its body.
