The sternum is the flat bone in the middle of the chest that connects to the collar bones (clavicles) and the ribs. to which skeletal system does the sternum belong? a. spongy skeleton b. compact skeleton c. axial skeleton d. appendicular skeleton

The correct answer is an axial skeleton.

The axial skeleton is the component of the skeleton, which comprises the bones of the trunk and head of the vertebrae. In the human skeleton, it comprises of six constituents, that is, the ossicles of the middle ear, the skull bone, the hyoid bone, sternum, the rib cage, and the vertebral column.

The axial skeleton in combination with appendicular skeleton forms the whole skeletal system of the human body. The sternum of the breastbone refers to the lengthened flat bone situated in the middle of the chest.

It links with the ribs through cartilage and produces the anterior of the rib cage, therefore, assisting in safeguarding the lungs, heart, and prime blood vessels from injury.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

explanation:

the sun shines white and black light to our planet. the white light has all the colors in it. in our upper atmosphere, we have dust particles and oxygen molecules. the white light meaning all of the colors in a rainbow shines through the upper levels of the atmopshere and the blue light scatters across the entire planet. that is why our sky is blue.
