Left ventricular hypertrophy, shortness of breath (dyspnea) and pulmonary edema are the effect that aortic regurgitation produces in the body.
The answer is population density
Answer:

Explanation: When two plate move towards each other they converge or come together. The collision between two plates that are moving towards each other is called a convergent boundary. When an ocean plate meets a continental plate at close to a straight line ( 180 degrees) the result is a subduction zone.
