Answer:prophase----the chromosomes shorten and thicken.the nuclear membrane has open up and the nucleolus has disappeared
Metaphase----the chromosomes migrate to the central plane of the cell and attach to the spindle fibres microtubules
Anaphase---the chromatids of each chromosomes part and move towards opposite poles of the spindle as the spindle fibres shorten
Telophase----the chromatids are in the polar end of the spindle .the spindle breaks down,the centrioles replicate,the nuclear membrane is reformed,the chromosomes gradually uncoil.

Answer:
The answer is B) arachnoid granulations
Explanation:
Arachnoid Mater and CSF Circulation:
- The arachnoid is the middle layer of the meninges which are the membranes covering the brain.
- The arachnoid is characterized by the spider web like projections that extend between it and the pia mater (outer membrane of the meninges).
- These projections are located in the subarachnoid space (space below the arachnoid). These projections contain the circulating cerebrospinal fluid or CSF.
- The arachnoid extends into the dural sinuses through the arachnoid granulations in which the CSF is filtered and added to the blood for drainage from the brain.
