A homologous structure is a structure or organ that can be found on many different animals that suggest that there is a common ancestor. It can be anywhere from a bone to a flap of skin to an organ. A common one to look at is the similarity between a human hand, bat’s wing, whale anterior flipper, and a cat’s paw. All of these have a common, 5-point structure to the bones which suggests that we all come from an animal that had 5 fingers.

Remember homeostatsis is when an organism's body tries to maintain adequate body temperature.This is done through the method of cooling.Furthermore ,in humans we sweat in order to achieve this cooling effect .that being said the only one here that would make sense is C)A dog panting after a long walk on a hot July day.The reason this answer would be correct is becausethis is a dog's method of cooling ,as they don't have sweat glands .Therefore they pant to maintain homeostasis.
