Answer:

The movement of the sun is causes by the rotation of the earth.  This is also why the moon goes across the sky.  Also, the earth doesn't go in an exact circle around the sun; instead, it is closer to the sun in the hotter months and farther in the cooler months.  Hope this helps with the answer.

yawa3891 [41]

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.

mihalych1998 [28]

Answer:

Through the process of Anthropogenic additions of N and P to the fresh water system can provide a strongest evidence for the above mentioned hypothesis.

Explanation:

As phosphorus is less mobile than nitrogen compounds, it is less likely to be found in fresh water where the organisms fail to access it. Phosphorus bounds mostly in the terrestrial ecosystem and in the aquatic matters because it has a sticky compound.

Thus it is a limited nutrient in freshwater lake like Mairead. However, this hypothesis can be different depending on other factors. Like, by adding anthropogenic N and P, this balance can be affected largely.
