The given blank can be filled with gas exchange.
In the mentioned diagram, the magnified structure shown is of alveoli. Alveoli are an essential component of the respiratory system that functions to exchange the molecules of carbon dioxide and oxygen to and from the bloodstream. These are the tiny-balloon configured air sacs situated at the very terminal of the respiratory tree and are aligned in groups all through the lungs.
1.The thermosphere: is used for orbitting satellites and increases in temperature as altitude increases.
2.Convection currents in the mantle cause the movement of crustal plates.
Answer:photosynthesis involved the process of energy build -up from monomers like carbon iv oxide and water (anabolism) with the help of solar energy while cellular respiration involved the breakdown of energy in the form of ATP with the help of oxygen (catabolism) into carbon iv oxide and water as waste products.
