Answer:
Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). This difference of one oxygen atom is important for the enzymes that recognize DNA and RNA, because it allows these two molecules to be easily distinguished inside organisms.

<span>Alveolar sacs are the part of the respiratory system where the exchange of air happens.
Inhalation is the
process where oxygen is taking in to the respiratory system thru the
nasal passageways and to the tiny alveolar sacs of the lungs. This
process also expands the lungs and the diaphragm heightens or elevates
upward.
The counterpart of inhalation is exhalation, where the
carbon dioxide is taken out of the lungs in opposite of the oxygen
passageways.
This two exchange is called the gas exchange or
respiration which happens in the respiratory system responsible for
enabling and providing oxygen throughout the body. </span>
