In a quiescent cell i.e. a non-dividing cell, Early endosomes containing AAV2 would most likely to move towards Centriole.
AAV2 is a non-envoloped virus.
Centrioles are the site of origination of microtubules which radiates outwards. They are non-membrane bound organelles found only in the animal cell. Microtubules are involved in different types of movement in the cell and are involved in the cell division by forming mitotic spindles. Microtubules facilitate the movement of the different organelles and vesicles in the cell.

What is elisa system?The enzyme-linked immunosorbent assay (ELISA), first described by Eva Engvall and Peter Perlmann in 1971, is a widely used analytical biochemistry technique. The assay employs a solid-phase type of enzyme immunoassay (EIA), utilizing antibodies against the target protein to find the presence of a ligand (often a protein) in a liquid sample. In addition to being utilized as a quality control check in numerous industries, ELISA has been used as a diagnostic tool in biotechnology, plant pathology, and medicine.

Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.
How is GFR regulated?The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.GFR is the sum total of filtration rates of all the working nephrons in the kidney.Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.Alpha receptors are more abundant on afferent arterioles.This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.This decreases blood flow to glomerulus, leading to decrease in GFR.Learn more about Glomerular Filtration Rate here:

The major differenc ebetween the use of scrubber and the use of fluidiozed - bed combustions as pollution control measures in power plants is?
The major difference between the use of scrubbers and the use of fluidized - bed combustions as pollution control measures in power plants is that fluidized bed combustions usually operate at a lower temperature whereas scrubbers require higher temperatures.
Mixing crushed coal with limestone is a part of fluidized bed combustion.
The limestone neutralizes a large portion of the sulphur dioxide in the coal. Finally, steam is produced by boiling water using the heat produced by combustion.
With the help of gas, water, and air, a scrubber may separate and remove particles that are in liquid or sludge form or that escape as clean gas.
In some circumstances, water droplets scrape sulphur dioxide and particles from exhaust streams, converting them to sludge that can be disposed of later.
The process starts with dirty air entering, combustion exhaust steam moving upward in mist, mist collecting particles and bringing them to the bottom of the unit, dirty water moving sludge to a removal system, sludge is separated from water and disposed of, water moving to the scrubber for reuse, mist collecting on screen, and clear air exiting.

Bacteria that release a toxin that forms a pore in red blood cells leading to hemolysis are using an alpha toxin to gain access to the nutrients inside the erythrocyte.
The best characterized and most potent membrane-damaging toxin of Staphylococcus aureus is α-toxin. It is expressed as a monomer that binds to the membrane of susceptible cells.
In humans, platelets and monocytes are specifically sensitive to α-toxin. They bear high affinity sites which allow the toxin to bind at concentrations that are physiologically relevant. A complex series of secondary reactions follow, leading to the release of eicosanoids and cytokines which in turn trigger the production of inflammatory mediators. These events cause the symptoms of septic shock that occur during severe infections caused by S. aureus.
