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.

Sladkaya [172]

Answer:

The correct answer will be option- Generalist species would be abundant in the biome.

Explanation:

A generalist species is the species that can survive in the wide variety of different resources and the environmental conditions.

The generalist species would be found in the higher number in biome which experiences large seasonal fluctuations with varying precipitation and temperature. The generalist species would be abundant because they can survive the changing environment, change in the conditions and wide range of food.

Thus, the Generalist species is the correct answer.

A cell with 80 chromosomes undergoes mitosis. How many chromosomes are found in the daughter cells? How many daughter cells are
Natalka [10]

Answer:

1. 80 chromosomes are found in each of the daughter cells. 2. Two daughter cells are produced. 3. The daughter cells are identical to each other.

Explanation:

Mitosis is simply a process of cell division whereby two daughter cells that are genetically identical are produced from a single parent cell. A cell having 80 chromosomes would undergo Mitosis through these various stages:

Interphase: This can be referred to as the rest phase between cell division when mature enough for reproduction. This is a preparatory stage where DNA is duplicated and ready for the division of chromosomes

Prophase: This stage marks the beginning mitosis of the cell with 80 chromosomes. The chromatin threads start a coiling process in which the chromosomes become condensed to enable easy distribution to daughter cells without tangling.  

Prometaphase: This phase commences toward the end of the prophase, where the nuclear envelop breaks down. The chromosomes move toward to the center of the cell.

Metaphase: At this stage, the duplicated chromosomes line up on the mid plane or equator of the cell. During this stage, each chromatid is condensed completely and appears thick and distinct.

Anaphase: At this stage, the chromosomes move toward the poles as each replicated copies of the DNA of the cell ends up on either side of the cell. What we would have here at this stage is an entirely two new sister chromatid having 80 chromosomes. Cytokinesis begins towards the end of this stage as the parent cell cytoplasm divides which also continues at telophase.

Telophase: This is the final phase of Mitosis where two separate nuclei are formed and Cytokinesis takes place to complete the division of the cell to form two daughter cells having the same number of chromosomes. These cells are genetically identical to the original parent cell.
