Answer:
During wet lime injection, a slurry of limestone (CaCO3) is sprayed into the spray column. The presence of SO2 causes gypsum (CaSO4. 2H2O) to be produced. Originally, the process was made up of two absorbers and an oxidation unit.
Explanation:
Photosynthesis is the answer. Green plants remove carbon from the atmosphere by photosynthesis.
Answer:
The virus that generates chickenpox disease is a virus of the family called "herpes" where once they infect the human organism they are not eliminated by human defense, but are reserved and coexist in the organism in the lymph nodes, and when faced with immunodeficiency situations for certain reasons, it generates their reactivation, manifesting a recurrence of the disease.
Explanation:
The chickenpox virus is called the Zoster chickenpox virus, once it infects the human in his childhood, it settles in the ganglion near where it is inactively inoculated.
This is reactivated again manifesting shingles or herpes zoster in adulthood and in situations of immunodeficiency as in those malnourished humans, or who are exposed to long hours in the sun, or who suffer stressful situations.
Shingles is a disease that manifests itself in a very painful way (more than chickenpox) in the form of scabs and vesicles in different possible areas.
Out of the following given choices;
a. they increase the amount of energy transferred from the
lungs to the blood
b. they increase the flexibility of the lungs as they expand
during inhalation
c. they increase the volume of the lungs, allowing more
oxygen to be inhaled
d. they increase the surface area of the lungs, allowing the
efficient gas exchange
The answer is D. Due to their microscopic nature, they are numerous in the lungs and are also circular-shaped so as to increase the surface area for gaseous exchange.
Other characteristics of alveoli that increase gas exchange are that they thinned-walled (with only a layer of cells) and moist.
