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.

Answer: (I hope you can understand this)
Type of operon: Trp
It’s a repressible operon
Lac
It’s an inducible operon.
Environment:
Trp
It’s deactivated when tryptophan is present in the environment.
Lac
It’s activated when lactose is present in the environment.
Repressor protein:
Trp
It’s activated by tryptophan.
Lac
It’s inactivated by lactose.
Transcription:
Trp
Tryptophan binds to the repressor protein, activating it.
Lac
Lactose binds to the repressor protein, deactivating it.
