The trachea, or windpipe, contains cartilage rings to maintain its structure, while the bronchi and bronchioles progressively decrease in cartilage as they branch into smaller airways. However, the alveoli, the tiny air sacs where gas exchange occurs, have no cartilage rings at all. Instead, they are composed of thin elastic tissue that allows for expansion and contraction during breathing.
Cobalt's atomic structure typically contains six electrons in its outer shell, which means it has six rings.
there are double rings in the purine bases and there is only a single ring in the pyrimidine base.
The molecule you are referring to is cholesterol. It has a structure composed of four fused rings, three of which are six carbon rings and one is a five carbon ring.
The trachea (windpipe) is held open by cartilage rings. These rings provide structure and support to the trachea, ensuring that it remains open for the passage of air during breathing.
Yes, diamond rings are made from diamonds, which are a form of carbon that crystallizes in a specific structure. Diamonds are classified as minerals because they are naturally occurring, inorganic solids with a definite chemical composition and crystalline structure. They are often cut and polished for use in jewelry, particularly in rings, due to their durability and brilliance.

The trachea has cartilaginous rings or Tracheal rings to support its structure and maintain a hollow interior in all positions.~Pain ^_^
Purines have two rings in their structure: a pyrimidine ring fused to an imidazole ring.
Purine nucleotides differ from pyrimidine nucleotides in their structure due to the number of nitrogen-containing rings they have. Purine nucleotides have a double-ring structure, while pyrimidine nucleotides have a single-ring structure.
Steroids are organic compounds composed of four fused carbon rings (three cyclohexane rings and one cyclopentane ring). They also typically have a side chain attached at carbon-17 and various functional groups at different positions on the rings. This rigid structure gives steroids their unique properties and allows them to interact with specific receptors in cells, influencing various physiological processes.
The trachea is a tube made of c-shaped rings of cartilage. This structure gives it flexible but strong support.

There are 27 carbon atoms in a molecule of cholesterol. 10 are not contained in the rings.
