Answer:
True
Explanation:
Diffusion is a passive process (no energy required) in which the substance such as liquid and gases moves from an area of high concentration to an area of low concentration.
During respiration, carbon dioxide diffuses from the blood into the alveoli and oxygen diffuses from alveoli to blood across the respiratory membrane. The partial pressure of oxygen is low in the blood of the pulmonary capillaries and high in the alveoli. so diffusion allow movement of oxygen across the respiratory membrane from the alveoli into the blood.
Hence, the given statement is true.
A closed system is a system that makes no physical or chemical exchanges with its environment. Of these systems provided as choices (tree, human, clock, car), only a clock does not make exchanges with the environment, except for energy.
Therefore, of that list, only a clock would be a closed system.
