Hair
What parts make up a human hair
cortex, medulla, cuticle
are fibers and hair distinguishably different
Yes fibers do not have cuticle medulla cortex
what are the radial lines
the straight lines shooting outwards
Is soil class or individual
class unless it contains DNA
In what order from inside to outside is human hair made up from.
medulla, cortex ,cuticle
what are a few ways fibers can be tested
burning smell ash speed burnt color of flame
What are concentric lines
the circular lines around
What are three ways to differentiate soil
color, what it contains, PH
Can DNA be pulled from hair
If the root is attached
is there anything such as natural fiber
Yes, Ex cotton
are radial on the same side or opposite
opposite
Is soil examined wet or dry
dry unless trying to determine the PH
Is it possible to tell if a root was forcibly removed
Yes it would be stretched or bent
what is an example of a synthetic fiber
Polyester, Rayon, Spandex
are concentric lines on the same side or opposite
same
Give an example of soil leading to solving a case
Finding pollen that leads to a certain type of tree that can only be found in a few places
What is the medulla to cuticle ratio of human hair
0.3333333333 or less
Can fibers be trace evidence
No not by themselves unless they contain DNA but they can support a theory.
how do you tell which impact happened first
By which radial lines stop and which ones continue
is soil being burnt a way to test
No
