Answer:
A. systolic pressure, ejection of blood from the heart
Explanation:
Systolic pressure represents the highest pressure of the blood in the arteries. It is attained during the phase of ventricular systole. During this phase, the ventricles contract (systole) resulting in a build-up of the blood pressure. This makes the tricuspid and mitral valves close. As the blood pressure in the ventricles exceeds that in the arteries, semilunar valves are opened and blood flows into the aorta and pulmonary artery. The flow of the blood increases the pressure in the arteries.
I would answer better if you showed me a picture of the cylinder(which is what your supposed to do) But the volume is LxWxH

This kind of outgrowth is mostly common in bone formation as they are used for muscle formation and attached to the tendons. As they are in the skin of humans and animals they are also found in plants as well especially orchid , cacti and certain member of the pear family</span>
Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion. A material containing such unstable nuclei is considered radioactive. Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely, proton emission.
