Verified step by step guidance

Understand the concept of antagonistic control in homeostasis: Antagonistic control involves two or more factors that have opposite effects on a physiological process, helping to maintain balance within the body.

Identify the role of insulin and glucagon: Insulin and glucagon are hormones that regulate blood glucose levels. Insulin decreases blood glucose by promoting its uptake into cells, while glucagon increases blood glucose by stimulating its release from storage.

Analyze the other options: Consider the role of adrenaline, melatonin, and blood vessel dilation. Adrenaline is involved in the stress response, melatonin regulates sleep cycles, and blood vessel dilation is a response to temperature changes, none of which involve direct antagonistic control.

Compare the options: Insulin and glucagon directly oppose each other's actions on blood glucose levels, fitting the definition of antagonistic control. The other options do not involve two opposing factors working together to maintain homeostasis.

Conclude the analysis: Based on the understanding of antagonistic control, insulin and glucagon regulation of blood glucose levels is the correct example of antagonistic control in homeostasis.
