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:
See below.
Explanation:
Other than Carbon Dioxide (CO₂), two carbon compounds found in plants are :-
- Glucose (C₆H₁₂O₆)
- Pyruvic Acid (C₃H₄O₃)
Answer:
The protein likely travels through a common lumen shared by thylakoid membranes and grana, and cannot easily diffuse through the thylakoid membrane.
Explanation:
There is a lot of scientific research in which a specific molecule can be labeled with some fluorescent marker (usually carbon 14). This type of marking allows the researcher to make observations about the movement of these molecules, as you can see in the question above. About the research shown in the question, the researcher realized that the protein labeled with the fluorescent marker moved between the grana and was always in the lumen, so she can conclude that the selocomovement protein moved through the lumen that is shared between the tilacoid membranes and the grana.
Famine- High population means more mouths to feed
Disease- Diseases usually spread more quickly with people who live closer( as it can just move from one person to the other)
War- People like to fight for land, resources, money, etc. And having more of those things mean they are more able to support families, communities, and more.

Explanation:
La principal diferencia entre la digestión mecánica y química es que la descomposición mecánica de partículas de alimentos grandes en partículas de alimentos pequeñas ocurre en la digestión mecánica, mientras que la descomposición química de compuestos con un alto peso molecular en compuestos con un bajo peso molecular
