Original formula Listerine is 26.9% alcohol, making it approximately 54 proof. According to the US, one "standard" drink contains roughly 14 grams of "pure" alcohol—so one standard drink of Listerine is 2.2 fl. oz. (so there are about 23 standard drinks in one 1.5 L bottle of Listerine).
The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.
Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.
Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.
Both facilitated diffusion and active transport requires the proteins present in the cell membrane.
The main function of the respiratory system is to allow the exchange of gases between the atmosphere and the lungs.
Hence,the only structure that carries out this function is the alveoli as other structures such as the nose,trachea and pharynx transport gases to the alveoli just so that it can can out its function.
