Which statement best explains homeostasis

I don't see the statement but if you are asking like "What is homeostasis?" Homeostasis is the process used by the body to maintain a stable internal environment. Either negative or positive feedback can be used in homeostasis. For instance, human sweats in hot weather and shivers in cold weather. 

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
