Death
Cuticle - Correct Answers -The cuticle is the outermost layer of the hair. It is consists of
flattened, scale-like cells which overlap one another
microscopic characteristics associated with the cuticle, such as the thickness of the
cuticle, the variation in the thickness, the presence of pigment, and the color. Also, the
nature of the outer cuticle margin may be smooth, looped, ragged, or damaged.
Cortex - Correct Answers -Home to pigment containing granules - gives hair color
Medulla - Correct Answers -This layer may be continuous, discontinuous, fragmentary,
or even absent. The diameter of the medulla is a useful characteristic in the
identification and comparison process
Gel Electrophoresis - Correct Answers -The separation of nucleic acids or proteins, on
the basis of their size and electrical charge, by measuring their rate of movement
through an electical field in a gel.
Medical Examiner - Correct Answers -A physician who performs an autospy when death
may be accidental or violent. He or she may also serve in some jurisdictions as the
coroner.
Forensic Medical Examiner - Correct Answers -● Examine human bodies from people

● Reporting findings to colleagues, law enforcement professionals, and court officials
FORENSIC DNA ANALYST - Correct Answers -● Analyzing evidence that can link
suspects with specific crime scenes
● Identifying samples of DNA, such as blood, hair follicles, or other bodily fluids
How is gel electrophoresis used? - Correct Answers -Gel electrophoresis separates the
DNA strands by size
Dehydration synthesis - Correct Answers -water is used to break apart 2 molecules
