In biology give reason/exhaled air has more carbon dioxide than inhaled air

Exhaled air has more carbon dioxide because the blood contains some carbon dioxide (a waste product) that is transferred to the air in the lungs, which is then exhaled. The result is that the exhaled air contains less oxygen and more carbon dioxide than the inhaled air. The air in the lungs also becomes humidified with water before it is exhaled.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

this is a good question! i'll do some research and come back when i have the answer!
