(2 points) High systolic, because when the heart pumps, the pressure inside the aorta would be greatest, causing the weak spot to rupture outward. atomic orbitals In the quantum mechanical version of the Bohr atomic model, each of the allowed electron orbits is assigned a quantum number n that runs from 1 (for the orbit closest to the nucleus) to infinity (for orbits very far from the nucleus). H As a result, when a low-mass nucleus absorbs nucleons, the added neutrons and protons bind the nucleus more tightly. That would be kinda sad but here the answer mate. The process is accompanied by the release of a large amount of energy. One way to accomplish that end is to heat fusion fuel to high temperatures so that the kinetic energy of thermal motion is sufficient to get the nuclei together. Almost all nuclear phenomena can be understood in terms of a nucleus composed of neutrons and protons. Over the years, these radiochemical techniques have been used to isolate and identify some 34 elements from zinc (atomic number 30) to gadolinium (atomic number 64) that are formed as fission products. 6.02 Note that the first two reactions must occur twice for the third to be possible, so the cycle consumes six protons ( The correct answer is "High systolic, because when the heart pumps, the pressure inside the aorta would be greatest, causing the weak spot to rupture outward".
