Just before hatching begins, the air cell expands to approximately 30% of the internal volume of the egg. As hatching begins, the beak of the embryo penetrates the inner shell membrane where it forms the inner wall of the air cell. The lungs begin to function, inhaling the air from the air cell.

What does a chicken egg air sack do?
egg+sperm =fertilised and start divide. In warm environment means the eggs were not kept in the right temperature. Cell division continue, taking its nutrition from the egg until become full chicken then start breathing, using the air inside the sac until it is able to break the shell and uses outside air
Does cold air kill roaches?
Yes, cold air can kill roaches, but it takes a prolonged period of being exposed to cold air to also kill the egg cases.
How does a chick get oxygen while developing inside the egg?
Like all embryos, a chicken in the egg does not require air to breathe until such time (approximately day 19) when their lungs develop enough to use the small amount they need. When it is first laid, the egg is full of yolk and albumen. At that time there is no air space as it is not required. The egg shell is porous. Moisture is lost through the shell over time and the moisture is replaced by air. When we breed chickens on the farm, we keep the small end of the egg up so the air collects above the developing chick. This air will be used by the fully formed chick inside the egg while it "PIPS" its way out of the shell at day 21.
How does a fish's bladder cause the fish to move like a submarine?
Their is an air chamber in most fishes just like in submarines. When it gets filled with air the fish moves up. While, when air is released the fish moves down. This is precisely what happens in a submarine.
Which end of an egg is not closely attached to the shell?
The large end or "air chamber"
Why doesnt an egg expand in a vacuum chamber?
Liquids are virtually incompressible, and the contents are liquid, plus the shell of an egg is partly permeable to air, so the small amount of air inside expands and leaks out readily.
What is an air chamber?
An air chamber is a chamber in a hydraulic system in which air is compressed to regulate the flow of a fluid.

How does oxygen and carbon dioxide get in and out of an amniotic egg?
The entire shell of the egg is covered in tiny little pores which allows for the passage of air and water into and out of the egg. The shell itself is recognized as a semi-permiable membrane. There is a chamber between the inner and outer soft membranes of the eggs (located just under the shell) that is actually hollow; it's an air cell. It grows as the chick does, surprisingly, but that's because as the chick gets older, it requires more CO2 to be transferred out of the egg, while allowing enough fresh oxygen to enter into the egg. The chick doesn't actually breathe into this chamber, the gasses are exchanged via an organ called the "allantois". This organ is responsible to handling liquid wastes and exchanging gases from the egg's air cell to the chick.
The innermost chamber of respiratory system into which air can be drawn is ..........?
innermost chamber of respiratory system into which air can be drawn is . Bronchiole
Propose a way to determine the density of air?
Get a vacuum chamber. Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber. Fill it with air, and then weight it again. Subtract the new weight from the initial weight to get the mass of the air contained within the chamber. Find the volume of the chamber as well. density= mass/ voume. Hope it heelpss(:
