Answer:
(A) True
Explanation:
The sun is producting the electromagnetic radiation which is the primary energy source on Earth and the driver of the entire climate system.
In general the sun is the source of energy that drives all life on Earth. This energy governs the weather, ocean currents and the hydrological cycles.
Without the continuous influx of sunlight and heat, life on Earth would cease to exist. The sun sets off the hydrological cycle, causing it to constantly evaporate into the atmosphere, from which it falls back to Earth.
Answer:
Option-D
Explanation:
Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.
The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.
The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.
Thus, Option-D is the correct answer.
Answer:
Carbon dioxide and water; organic molecules and oxygen; chemical potential; usable chemical energy in the form of ATP; heat energy that cannot do work
<u>Explanation</u>:
- Cellular respiration produces <u>carbon dioxide and water</u> from <u>organic molecules and oxygen</u>; organic molecules are a source of <u>chemical potential energy</u> that cellular respiration transfers into <u>usable chemical energy in the form of ATP</u> and transforms into <u>heat energy that cannot do work</u>.
- <u><em>Cellular respiration</em></u> is a process that takes place in the mitochondria in living organisms cells. It is the powerhouse of a cell.
- <em><u>The process involves the break down of organic molecules such as glucose, in presence of oxygen, to generate energy in the form of ATP, which is the usable form of energy by the cells to drive processes such as transport, growth and development, etc.</u></em>
- The process converts chemical potential energy in organic compounds to usable chemical energy in the form of ATP. Carbon dioxide and water are also produced as by-products during the process.
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.
The S phase is when a Cell's DNA is copied. This is otherwise known as mid-interphase.
hope this helps!!
