Answer:
Floating ribs
Explanation:
The thoracic cavity has 12 pairs of ribs evenly distributed on the left and the right sides of the cavity that function to provide surface area for muscle attachment such as the intercoatal muscles that assist in breathing. The ribs are flat shaped bones semi circular in shape attaching to the thoracic vertabrae with a wider. The first to the tenth ribs are linked to the sternum by a cartilage to assist in their epansion and relaxation during breathing. The 11th and 12th ribs have no cartilage that can attach them to the sternum and hence are called floating ribs.
Estuaries are important natural places. They provide goods and services that are economically and ecologically indispensable.
Answer: Forming the embryo and providing DNA.
Explanation: The egg is a cell that is used to reproduce. It is the very beginning of what will become the embryo and eventually the baby. The sperm fertilizes the egg and contributes 50% of the embryo DNA to the ova (the other 50% of DNA comes from the egg, however sperm only contributes DNA to the egg during the fertilization process whereas the egg has a much more important role). The sperm and egg meet, the egg becomes fertilized and loaded with the DNA it needs to form. The egg provides nutrients needed for the embryo to grow until it is fully gestated.
