Give reasons why-
i. The amount of nitrogen gas remains same in inhaled and exhaled air.
ii. Fishes die when they are taken out of water.
iii. Carbon monoxide is a harmful gas.
iv. Mountaineers carry oxygen cylinder with them.
Answers
Answer:
because nitrogen is not used by the body for any of the physiological processes
leaving the blood vessels no longer exposed to oxygen in air
when breathed because it displaces oxygen in the blood and deprives the heart, brain and other vital organs of oxygen
in high altitudes atmospheric pressure is low which makes air less dense
Explanation:
The amount or volume of nitrogen gas inhaled by the body is equal to the amount of nitrogen gas exhaled by the body. This is because nitrogen is not used by the body for any of the physiological processes
Though some fish can breathe on land taking oxygen from air, most of the fish, when taken out of water, suffocate and die. This is because gill arches of fish collapse, when taken out of water, leaving the blood vessels no longer exposed to oxygen in air.
Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain and other vital organs of oxygen. ... But even if you recover, acute poisoning may result in permanent damage to the parts of your body that require a lot of oxygen such as the heart and brain.
f) Mountaineers carry oxygen cylinders with them because in high altitudes atmospheric pressure is low which makes air less dense. This makes the volume of Oxygen for breathing very less.
