Hyaline cartilage makes up the costal cartilage that holds the ribs to the sternum. The most prevalent form of cartilage in the body is hyaline cartilage.
<h3>What is hyaline cartilage?</h3>
On the articulating surfaces of bones, in the larynx, trachea, and bronchi, as well as on the sternal ends of the ribs, hyaline cartilage is present. It imparts a rigid yet malleable form to the constructions.
Hyaline structures are connective tissues that anchor the ribs onto the sternum. Such structures and joints are robust because collagen fibers are present, but their mobility and flexibility are constrained. To reduce friction and provide cushioning at the joint surface, articular cartilage, also known as hyaline cartilage, covers the ends of bones.

Answer:
The fish did not yet exist when the old layers of rocks were deposited. In fact, animals with hard parts did not evolve until about 600 million years ago, which is only about 13% of the 4.5 billion year age of the Earth. Multicellular animals without hard parts left tracks in older sediments, but had no fossilize-able body parts.
Explanation:
Answer:
B. 20%
Explanation:
The complementary base-pairing rule states that Adenine always pairs with Thymine (A with T), and Cytosine with Guanine (C with G).
Because of this, the amount of Adenine present must be the same as the amount of Thymine present, and the same for Cytosine and Guanine.
This means that if there is 30% Adenine, there is also 30% Thymine as each A base is paired to a T base. This adds to 60%, so Cytosine amounts and Guanine amounts must add to 40% to make 100%.
Since they are equal in amount, there must be 20% of each.
Therefore the answer is B. 20%
There is 30% Adenine, 30% Thymine, 20% Guanine and 20% Cytosine.
Hope this helped!
