1.For birds to be able to take flight or fly high enough and still obtain enough oxygen, the birds have air sacs.
2.(Air sacs are membranaceous receptacles which communicate with the cavities of the respiratory organs passages, and can through be filled with air.)
I really hoped this helped, now remember the answer to the question is number 1. The definition of air sacs is number 2.
allow them to obtain oxygen from the air, such as aerial roots.
All have adaptations to some extent. However in some cases they are insufficient to allow flight. Ostriches cannot fly for instance, though they have wings. It can be argued that penguins 'fly' under water.

Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!
Humans cannot fly without technology or equipment. Our bodies are not designed for flight and lack the necessary physical adaptations, such as wings, to allow for sustained flight.
No domestic airline offers a direct flight from Hawaii to Fort Lauderdale, Florida. There is not enough fuel storage on a commercial airliner to allow such a flight.
Cranes have special adaptations, such as strong wings and lightweight bodies, that allow them to fly at high altitudes over mountains like Mt. Everest. They have a large wingspan relative to their body size, which helps them generate enough lift to navigate the thin air found at high elevations. Additionally, their efficient respiratory system enables them to extract enough oxygen from the air to sustain flight in such challenging environments.

screech owls can see in the dark, rotate around their head, and are nocturnal !!!!!!!!!!!
In order to have a proper blue flame the air valve must be opened enough to allow enough oxygen to enter during the combustion process. Be aware that too much oxygen will not allow the gas to ignite and too little oxygen is noticed by a yellow flame caused by incomplete combustion and the burning of carbon.
Yes, you can pick up your luggage on a connecting flight if you have a layover long enough for you to collect and recheck your bags. Make sure to check with your airline for specific instructions and allow enough time to do so during your layover.
