The most biologically devastating oil spills in the marine environment are usually a result of the sinking of oil tankers.
An oil spill is a type of pollution that occurs when a liquid petroleum hydrocarbon is released into the environment, particularly the marine ecology.
Oil releases into the sea or coastal waterways are generally referred to as marine oil spills, however land-based spills are also possible.
Oil spills can result from crude oil discharges from tankers, sinking of oil tankers, offshore platforms, drilling rigs, and wells as well as refined petroleum products (like gasoline and diesel) and their byproducts, heavier fuels used by big ships like bunker fuel, or the spill of any oily waste or garbage.

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.
