CHS exam 2 review study guide based
questions and answers6
Type B blood - ANSWERS-Contains B antigens
Antibodies - ANSWERS-Formed to destroy or inactivate specific antigens
Luminol - ANSWERS-Reacts with blood causing it to luminesce
Blood type for a sample - ANSWERS-Determined by testing anti-A serum and observing
agglutination
Chromosomes - ANSWERS-Threadlike bodies that carry genes
Genotype - ANSWERS-Combination of genes present in the cells of an individual
Phenotypes - ANSWERS-Observable characteristics resulting from the interaction of genes
Harder and nonporous surfaces - ANSWERS-Result in less spatter
Shape of bloodstains - ANSWERS-Provides information regarding direction, dropping distance,
and angle of impact
Pointed end of a bloodstain - ANSWERS-Faces the direction of travel
, Satellite blood spatter - ANSWERS-Has the pointed end facing against the direction of travel
Bloodstain with a diameter of 2mm - ANSWERS-Could be classified as medium-velocity spatter
Pattern created when blood-covered object flings blood in an arc onto a surface - ANSWERS-
Known as cast-off
Ratio of length divided by width - ANSWERS-Used to approximate the angle of impact of a single
bloodstain
String method - ANSWERS-Used to determine the area of origin using bloodstain pattern
Area within a deposited spatter pattern that is clear of spatter - ANSWERS-Known as a void
pattern
Method for documenting bloodstain pattern evidence - ANSWERS-Involves setting up a
rectangular border of rulers around the pattern
Blood, saliva, vaginal secretions, hair, bone, and semen - ANSWERS-All types of biological
samples
A forensic scientist should assume any samples found in a crime scene - ANSWERS-Are human
Amylase Test - ANSWERS-Used for saliva sample
Kastle-Meyer - ANSWERS-Used for blood sample
Acid-Phosphatase Test - ANSWERS-Used for semen sample
