Which example most clearly shows homeostasis in the body?
Answer and explanation
Correct answer: Insulin controlling blood sugar when it rises
Homeostasis is the maintenance of a relatively stable internal environment despite changes. When blood glucose rises, pancreatic beta cells release insulin; body cells take up more glucose and the liver can store it as glycogen, bringing the level down toward normal. Therefore option A directly describes internal regulation. Options B, C, and D are plant movements or tropic responses to external stimuli, not regulation of an animal’s internal conditions.
