Coracias garrulus is a blue bird with an orange-brown back. The offspring of this bird have an effective defense mechanism. The
young birds vomit and cover themselves in a foul-smelling orange liquid when they sense a threat by predators. Which two systems alert the young bird to the danger and help produce the vomit it uses as a defense
The correct answer is - Nervous and digestive systems.
Explanation:
Coracias garrulus is a bluebird that has a unique defense mechanism in which it senses the danger or threat they vomit and cover themselves with their foul-smelling orange-yellow vomit.
The orange vomit or liquid store in the digestive system of the bird and when the bird's sense threatens it activates its nervous system which then intern sends a signal to the digestive system and the urge of vomit on its young ones and cover in that.
My hypothesis is that the Hawaiian Island chain was formed by a hot spot in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. My data supports my hypothesis because as the plate moved over the hot spot, the islands that make up the Hawaiian Island chain were formed.
