Question

multiple choice question
the function of the cranium in chordates is to ________.
o surround and protect the brain
o provide a point of balance
o cushion the embryo
o surround and protect the notochord

Explanation:

The cranium is a bony structure in chordates. Its main function is to enclose and safeguard the brain. The other options are incorrect: providing a point of balance is not its primary role; cushioning the embryo is not relevant to the cranium's function; and the notochord is a different structure (in vertebrate chordates, the vertebral column replaces the notochord in providing support, and the cranium is for brain protection).

Answer:

surround and protect the brain
