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>

Explanation:
It says so on a amino acid codon chart.
Hope it helps!
Sorry if incorrect.
Answer:
True
Explanation:
Carbohydrates products primarily glucose, galactose and fructose are absorbed in the small intestine. The apical membrane with in the small intestine absorbs Glucose and galactose while fructose is absorbed through facilitated diffusion via GLUT5
However, amino acids are absorbed by Sodium cotransporter. Sodium cotransporter is found in the intestinal mucosa of small intestine and then transported via facilitated diffusion across the basolateral membrane
Hence, the given statement is true
The carrier proteins<span> facilitate diffusion of molecules across the cell membrain</span>
I believe the answer is Striae gravidarum. They are also known as pregnancy stretch marks, is a specific form of scarring of the skin of the abdominal area due to sudden weight gain during pregnancy. They reflect separation within the underlying connective tissue of the skin. After birth they usually fade, although they never disappear completely.
