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.

explain the differences between normal air circulation and how the air behaves when a temperature inversion occurs
dybincka [34]

Temperature inversion or thermal inversion is a phenomenon during which the temperature increase when there is an increase in the altitude. It is an uncommon process that happens in the troposphere-the layer of atmosphere closest to the earth.    

When there is an increase in temperature with altitude, that warm air acts as a blockage for the cool air near the surface of the earth. So this is just opposite to the normal behavior of the air, where it becomes cooler with an increase in altitude.

So how air circulation behaves during inversion?

So as we said that the cool air nearer to the earth will be blocked by a layer of warm air. This blockage will hinder the circulation of air upwards from the lower layers. Let’s see how:

• As we know that, warm air is less dense and more buyout than cool air and normally less dense warm air is close to the earth and cool air is in above layers. But when the process is reversed, this warm air acts like a blanket for the proper circulation of air. Due to this, many environmental pollutants which normally leave the earth during air circulation get trapped in our air.  

• The trapped environmental pollutants like nitrogen oxides and hydrocarbons get convert into harmful ozone that ultimately deteriorates the quality of air and causes problems like smog.

• The improper air circulation also causes suspension of the harmful gases near the earth instead of allowing them to leave the earth atmosphere. This ultimately causes air pollution.  

• When smoke will not rise, carbon dioxide will be build up in the atmosphere; this will cause greenhouse effect and global warming.

Therefore, air circulation behaves very different during temperature inversion process and poses hazardous effects on global climate.

Hope it helps! :)

Answer:

Chloroplast

Explanation:

Both plant and animal cells have mitochondria, nuclei, and cell membranes. However, only plants have chloroplasts, as they need them to photosynthesize. Animals don't photosynthesize, so their cells don't contain chloroplasts. Hope this helps!
