The one that makes sense is C.) "The skull is hard which protects the brain from being injured." here's why:
Explanation:
The skull performs vital functions. Mainly, it supports and protects the head's soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull. The mandible is the only bone that separates from other parts of the skull. The skull or known as the cranium in the medical world is a bone structure of the head. It supports and protects the face and the brain. The adult skull has a total of 22 individual bones. They don’t move and united into a single unit. The skull performs vital functions. Mainly, it supports and protects the head’s soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull. The mandible is the only bone that separates from other parts of the skull. So, as our cranium grow it gets tough enough to protect the brain from injury!
These antimitotics (i.e. taxanes) target microtubule proliferation. The stage of mitosis where it acts is at the M-phase, particularly in the metaphase. The phases of mitosis are prophase, metaphase, anaphase, and telophase. Microtubles first appear at the metaphase.
