Answer 1:
Seismic waves, the waves of energy that travel through the Earth as a result of an earthquake can tell us a lot about the internal structure of the Earth because these waves travel at different speeds in different materials. There are two types of waves that travel through the Earth: p-waves and s-waves.
P- waves are faster and they can travel through both solids and liquids. S-waves are slower and cannot travel through liquids. For both kinds of waves, the speed at which the wave travels also depends on the properties of the material through which it is traveling.
Scientists are able to learn about Earth’s internal structure by measuring the arrival of seismic waves at stations around the world. For example, we know that Earth’s outer core is liquid because s-waves are not able to pass through it; when an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive. Similarly, we know that the earth has a solid inner core because some p-waves are reflected off the boundary between the inner core and the outer core. By measuring the time it takes for seismic waves to travel along many different paths through the earth, we can figure out the velocity structure of the earth. Abrupt changes in velocity with depth correspond to boundaries between different layers of the Earth composed of different materials.
Explanation:
*High ventilation/low perfusion that Increased the cardiac output Decreased of the pulmonary vascular and the resistance and *Pulmonary hypertension,*Reduced the left ventricular preload
Pulmonary hypertension is happens when the pressure in the blood vessels and leading from the heart and the lungs is too high. With the pulmonary hypertension, the blood vessels in the lungs to develop the increased amount of muscle in wall of the blood vessels
It's a serious condition which can be damage the right side of the heart. and The walls of the pulmonary and the arteries to become the thick and the stiff, and that cannot be expand as well they allow blood through.

Answer:
As objects move around over time, the energy associated with them—e.g., kinetic, gravitational potential, heat—might change forms, but if energy is conserved, then the total will remain the same. Conservation of energy applies only to isolated systems.
