The answer is Mullerian mimicry.
Mullerian mimicry is a kind of mimicry in which two or more poisonous animals generate identical presences as a shared protective tool. The theory behind this is that if a predator learns to avoid one of the poisonous species, it will also avoid the mimic species as well.
It is a natural process in which two or more often repugnant species, which may or may not be closely associated and share one or more common predators, have started to mimic each other's cautionary signals, for their communal benefit, as predators eventually learn to avoid all of them.

Answer:
Glucagon signals the liver to start producing glucose.
Explanation:
Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.
