A.
Floating ribs in humans - 4
There are 12 pairs of ribs in human, which form the bony lateral walls fo the thoracic cage. The last two pairs of ribs (total four) are called floating ribs because their anterior ends are not attached to either the sternum or the cartilage of another rib. The floating ribs protect the kidneys. There are 7 cervical vertebrae in humans present in the neck. The first cervical vertebra is called atlas second is known as an axis.
There are 20 amino acids found in proteins.
