Weiru is taking 14 breaths per minute. Her vital capacity is 3000 mL, her total lung capacity is 4000 mL, and her tidal volume is 450 mL per breath. Calculate the following: A. Weiru's total pulmonary ventilation (minute volume).B. Weiru's alveolar ventilation rate.

not only is it colder, it also becomes darker, less salty, and more dense.

they had the law tat factories that produces smoke cannot be built near residential buildings.

hope this
