Yes based off of the questions I could say China
Smooth muscle.
Blood vessels contain smooth muscle in their walls. Cardiac muscle is heart muscle specifically. Skeletal muscle is muscle that forms the voluntary muscles.
cAMP in the cytoplasm
Many cAMP can be generated as a second messenger to amplify the signal in response to hormone binding.
The answer is underwater eathquakes.
Earthquakes are a shaking of the ground that when observed on earth, can cause many damages mainly on hills and mountainsides causing avalanches. When they occur underwater though, the water gets lifted (normally from the sea) and generates giant waves that can sometimes reach the coast.
