Question

when carbon reacts with oxygen, carbon dioxide gas is produced.


(a)which is the gas obtained in either increarsing the amount of carbon or decreasing the amount of oxygen in the above process?​

Answer 1

Answer:

Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs. The air in the lungs has a higher concentration of oxygen than that of oxygen-depleted blood and a lower concentration of carbon dioxide. This concentration gradient allows for gas exchange during respiration.
