Answer:
The function of pulmonary ventilation is to b. maintain adequate alveolar ventilation.
Explanation:
<em>Pulmonary ventilation refers to the movement of air into and out of the lungs, so its main function is to maintain adequate alveolar ventilation.</em> The air moves out of the lungs when the pressure inside the lungs is greater than the pressure in the atmosphere. In the lungs, Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. That's how the oxygen gets into the bloodstream.
Answer:
Chemical Change
Explanation:
Chemical Change. Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties.
The correct answer is: In DNA and RNA, a phosphodiester linkage connects the 3' carbon of one nucleotide and the 5' carbon of another.
The phosphate of one nucleotide is covalently bound to the sugar of the next nucleotide in DNA molecule (or hydroxyl groups in phosphoric acid react with hydroxyl groups on 3' carbon atom of one sugar molecule (deoxyribose) and the 5' carbon atom of another sugar molecule (deoxyribose) to form two ester bonds). In RNA molecule linkage is between the 3' carbon atom of one sugar molecule (ribose) and the 5' carbon atom of another, (ribose).
Hydrolysis of phosphodiester bonds is catalyzed by the action of enzymes phosphodiesterases.
