Arrange the sequence of steps in the development of heart failure. 1. oxygen delivery is reduced and heart failure occurs 2. the heart pumps blood less efficiently 3. fat deposits build up along artery walls 4. blood pressure increases and cardiac muscles thicken 5. blockage in arteries obstructs blood flow, and can cause heart attacks

1st: Fat deposits build up along artery walls

2nd:  Blockage in arteries obstructs blood flow, and can cause heart attacks

3rd: Blood pressure increases and cardiac muscles thicken

4th: the heart pumps blood less efficiently

5th: oxygen delivery is reduced and  heart failure occurs

I belive this is the correct order this is what my test corrections came back as.

Hope this helps!

explanation:

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
