Answer:

a. the virus must be able to cross-link red blood cells directly.

Explanation:

Viral hemagglutination assay is a method which is used for the quantification of the relative concentration of the viruses.

The principle on which the hemagglutination assay works is as follows:

  1. There are sialic acid receptors present on the surface of the red blood cells which will bind to the haemagglutinin glycoprotein present  on the surface of the viral particle. 
  2. Due to the binding of the sialic acid receptors with haemagglutinin particle there will be cross-linking of the red blood cells by the viral particles and a lattice formation will take place. 
  3. The lattice will remain suspended in the solution however if the concentration of the virus particles will be less, the lattice will settle down in the well. 

Thus, this method allows knowing the relative concentration of the virus. 

<em>Due to its basic principle of cross-linking this method works well for only a few viruses such as influenza virus. </em>

If the eyepiece has a magnification of 10x, what would be the total magnification of an image if you were using the lower power
motikmotik
<span>To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.</span>

In order to communicate with multiple cells at the same time, an axon may branch along its length, producing side branches calle
Dmitry_Shevchenko [17]

Answer: Collaterals

Explanation:

 According to the given question, the collateral is one of the side branch in the blood vessel and it is also known as the subordinate part in the vessel.

The main function of the collateral is that it basically developing the shunt blood circulation at the block vein or artery areas and plays an important role at the time of surgeries.

An axon is basically branch producing the branches at the similar time for the communication purpose is know as the collateral. Therefore, Collaterals is the correct answer.
