Answer: c.initiation of some nerve impulses
Explanation:
Cerebrospinal fluid is a clear, colorless fluid that can be found in the brain and spinal cord. It is secreted by meninges and choroid plexus. It is absorbed by the arachnoid granulations.
The primary function of the CSF is to act as a cushion to the brain within the skull to serve as a shock absorber and prevents the injury from the blow. It also circulates the chemicals and nutrients filtered from the nerves and also removes the waste from the brain produced by the cerebral metabolism hence reduces the wastes from the brain.
The cerebrospinal fluid does not function in the initiation of the nerve impulses.
It is free to bind to another promoter and begin transcription.
There is no prescribed length of time it takes to photographically document a crime scene. The amount of time spent depends on the size and complication in the crime scene, how much there is to document and environmental factors like weather or danger to the investigative team. It can consist of thousands of photographs and hours of work.
Crime scene photography should not just focus on the obvious. The purpose of crime scene photography is to document what is there and where it is in relationship to the scene, whether it is obviously connected to the crime or not. For example, a photographer in Florida shot the inside of every cabinet and the refrigerator at a homicide scene in a home, just as a matter of procedure. It was later discovered that the victim had a receipt for a six-pack of beer, matching the beer shown in the photograph of the refrigerator. Relatives noted that the victim did not drink beer. Further investigation led the team to the convenience store where the beer was purchased and the surveillance tape showed the victim with an unknown person purchasing the beer. It turns out that the victim had picked up a hitchhiker, purchased beer for that person and come back to the house. The photograph of the refrigerator contents had created the link enabling the investigators to find the suspect.
