The question is incomplete as it does not have the options which are:
- Adjusts the positions of the head, the neck, and the trunk
- Perform respiratory movements
- Stabilize or position parts of the appendicular skeleton
- All of the above
Answer:
All of the above
Explanation:
The axial skeleton is the group of bones which forms the centre of the skeletal system. The central portion of the skeletal system includes bones of the skull, bones associated with the skull, the thorax, and the vertebral column (spinal cord).
There are 80 axial skeletal bones out of which 22 bones are present in the skull, 7 attached to the skull, 25 in a thoracic cage and 26 in the vertebral column.
The axial skeleton help maintains the position of the appendicular skeleton, maintain the posture of the body by maintaining the posture of the neck, head and trunk and also help in the respiratory movements.
Thus, all of the above is correct.

A scientist named Hans Christian Gram made 2 kinds of bacteria that is based on their differences in the cell walls. The gram positive and the gram negative.There are differences on these 2. One of it is that Gram negative are more resistant with antibodies compared to the gram positive. Example of these would be pseudomonas aeruginosa while for the positive would be Staphylococcus. Another difference between the 2 would be for flagellar structure in gram negative have 4 rings while positive has only 2.
