what is the relationship between exposing to a virus and developing immunity to it? cite evidence from the text to support your
den301095 [7]

Answer:

Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.

Explanation:

Viruses are biological agents that can produce diseases when they enter the body of a living being.<u> In response to contact with a virus, the</u><u> immune system</u><u> synthesizes specific </u><u>antibodies</u> to combat the foreign biological agent.

Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).

An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.

The acquired immunity, mediated by antibodies, is the base for the development of vaccines.

The total metabolic rate is the total energy used by the body each day. Physical activity such as Training for a marathon require more energy and leads to increasing the tmr. Whereas, malabsorption of nutrients lowering the tmr because less food is being supplied,  and therefore less energy production.
