The choices are:
<span>A. Matrix protein
B. Hemagglutinin
C. An ion channel
D. Neuraminidase
</span>
The right answer is B. Hemaglutinin
Explanation:
Haemagglutinins are triangular rods. They allow the attachment of Influenzaviruses on the target cells of the respiratory tree. In the presence of red blood cells, a haemagglutination (liquid medium) is obtained.
<u>About the other components of Influenza virus:</u>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 Influenzavirus types A, B and C. They induce the synthesis of non-protective antibodies fixing the complement.
Answer:
C
Explanation:
Causes and increase in green house gasses such as CO2, N, and similar harmful gases.
<span>The answer is D. Interstate Highway System. The United States envisioned a highway system that would allow for controlled access to the road with no stop lights and a higher speed limit. This would allow for a faster means of transportation for goods and people throughout the country. In modeling this highway system, the United States looked to the autobahn in Germany after seeing how successful it was.</span>
