Which of the following outcomes is observed during rabies virus pathogenesis?

a) rabies virus replicates rapidly in muscle cells prior to traveling to the peripheral and central nervous systems.
b) rabies virus causes infected muscle cells to rupture after viral infection and replication.
c) negri bodies are a diagnostic sign of rabies virus infection.
d) administration of post-exposure prophylaxis after the development of neurological symptoms is an effective way to limit progression of rabies viral illness.

c) Negri bodies are a diagnostic sign of Rabies virus infection.

Explanation:

Rabies is an infection caused by rabies virus which affects the neurons and causes inflammation of the brain. It is a deadly disease and many animals are carriers of this disease like dogs, cats, raccoons, wolf, bats, fox, etc.  

It is diagnosed by the presence of Negri bodies in the cytoplasm of nerve cells. Negri bodies are inclusions that are round or oval shapes having a size between 0.25 to 27 μm. Negri bodies can be frequently diagnosed in Purkinje cells of the cerebellum and pyramidal cells of Ammon’s horn.  

Apart from these cells, they can be found in various ganglia, neurons of the tongue and other organs. So the correct answer is c.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
