ELEN [110]3 years ago
5 0

Answer: Option D

Explanation:

Once the pathogen enters the body, it starts dividing and after a certain period of time the patients experience some sign and symptoms of illness.

The prodromal period occurs just after the incubation period. In this phase the pathogen keeps on dividing and the host begins to experience general symptoms and signs of illness.

This is a result of the activation of immune system of the body which results in the swelling, pain, soreness.

The hormone vasopressin stimulates the kidneys to retain water.

Vasopressin or antidiuretic hormone is secreted by the posterior pituitary gland and acts on the nephron tubules which increase the reabsorption of water, thus decreasing water content in urine while increasing that of blood.

The increase in water concentration in the blood elevates blood pressure as well as blood volume which makes the urine concentrated.

It regulates the tonicity of body fluids and therefore, in response to hypertonicity stimulates the kidneys to reabsorb solute-free water and return it to the circulation from the tubules of the nephron, thus restoring the tonicity of the body fluids toward normal.

Radda [10]
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.
