ttagcatcagcctata
I hope this makes sense, if it doesn't then let me know. Have a Great day!
The correct answer is A. Provides body tissues with oxygen
Explanation:
The respiratory system includes different organs such as the lungs, diaphragm, trachea, etc. that allow organisms especially animals to exchange gases that are necessary to survive. This mainly occurs as oxygen is taken from air or water in the case of fish and other aquatic animals and this provides the body tissues with oxygen that is necessary for multiple processes and at the same time it takes out the carbon dioxide through exhalation.
