Which of the following statements are true concerning how an influenza virus identifies and infects its target cells?

The right answer is B. Hemagglutinin

Explanation:

About the other components of Influenza virus:Neuraminidase is a mushroom-shaped spike composed of a tetramer consisting of 4 subunits of a single glycoprotein. At 37 ° C, the neuraminidase destroys the bonds (virus - cells) and thus allows the release of neoformed virions in the external environment: it is elution.

The membrane protein M and the protein subunits of the nucleocapsid are antigenic and are the basis of the classification of Influenza virus types A, B and C. They induce the synthesis of non-protective antibodies fixing the

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
