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:
- 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.
- 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.
- 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>
Normally, oxygen from the blood cells supply your muscles with the energy it needs to carry out certain actions. However, when there isn't enough oxygen to support the muscles, it produces lactic acid, or fermentation, to make up for the oxygen. (That's why you get that burn-y feeling whenever you exercise!)
A hypothesis that has been verified by many scientists is called a scientific theory. Scientific theory can be derived from careful examination of facts and thorough testing and proving of the different scientists. A hypothesis is an intelligent guess about a certain situation or problem. Whenever this hypothesis would be verified many times by many scientists, this would be<span> under now the category of scientific theory.</span>
Meiosis since they are sex cells just look at the letter e and put s in top and x bottom and that is how you know
The answer to your problem is question 3 i just took that test i got it right
