3 elements: calcium, carbon, and oxygen
Answer;
When only white and red lights are visible, you are approaching the port side of a powerboat and thus you should give way to your starboard side.
Explanation;
-The red and green lights are called sidelights (or combination lights) because they are visible to another vessel approaching from the side or head-on. The red light indicates a vessel's port (left) side; the green indicates a vessel's starboard (right) side.
-When only a white light is visible, one may be overtaking another vessel. Give way to either side. Additionally, when only a red light is visible, you are approaching the port side of a sailboat.
a) It never needs batteries.
b) It's designed for extremely active patients.
c) It's specifically designed for long-term use.
d) An LVAD only supports a failing left ventricle.
Answer:
d) An LVAD only supports a failing left ventricle.
Explanation:
When both halves (R.&L Ventricles) of the heart failed to pump blood, together with the failure of the valves to regulate blood flow as in biventricular failure, <em>a device can planted in the patient to replace the failed right or let ventricles and to control the directional flow of blood to the vascular system. This device is called TAH.</em>
However when the left ventricle is faulty so that blood pump into the systemic circulation is affected in case of a patient who is <u>waiting for heart transplants not old enough for transplants;</u> <u>who needs to sustain heart function after surgery</u>; or <u>patients who could not find a heart donor and therefore need to survive</u>, <em>a mechanical pump is implanted below the diaphragm and power by battery cell in a wearable outside. This miniature mechanical pump is called Left venticular assist device(LVAD).It only correct left ventricle anomaly</em> .
Thus the major difference between the two is that LVAD, is only for the faulty left Ventricle correction.
They help in that, many recently discovered fossils form series that trace the evolution of modern species from extinct ancestors. Patterns in the distribution of living and fossil species tell us how modern organisms evolved from their ancestors. Evolutionary theory explains the existence of homologous structures adapted to different purposes as a result of descent with modification from a common ancestor.
