What is the function of the air space on a egg?
The air space in an egg serves as a cushion that helps protect the developing embryo from shocks and temperature changes. It also allows for gas exchange, which is vital for the embryo's respiration as it grows. As the egg ages, the air space increases due to moisture loss, indicating freshness and potential viability for incubation.
Name a gas whose concentration is the same in inhaled air and exhaled air?
Nitrogen is a gas that is present in the same concentration in inhaled and exhaled air, as it is not chemically changed by the body during respiration.
What does gas need for respiration?
Oxygen is the gas that is required for respiration.
What gas do humans take from the air and absorb into the blood?
Humans take oxygen from the air and absorb it into the blood through the process of respiration.
