1.1.1-1.1.6 Exam UPDATED Exam
Questions and CORRECT Answers
forensic scientist - CORRECT ANSWER - investigates crimes by collecting and analyzing
physical evidence
Search Methods - CORRECT ANSWER - Evidence may be located using a systematic
approach to survey the site. These methods employ spiral, grid, line, or zone techniques.
Point of Origin - CORRECT ANSWER - The point of origin is the point where they take
all measurements from within the scene perimeter.
Key - CORRECT ANSWER - The key indicates important objects that are marked with a
specific number/shape. In this case, the keys were the evidence markers.
Legend - CORRECT ANSWER - A list that identifies patterns, symbols, or colors used in
a chart
Scale - CORRECT ANSWER - Specify a percentage of original size to enlarge or reduce
the size of an object.
Person of Intrest - CORRECT ANSWER - A person being questioned in connection to the
crime.
Physiological Response - CORRECT ANSWER - the pattern of chemical and electrical
activity that occurs in sense organs, nerves, and the brain, as a result of the stimulus.
Stimulus - CORRECT ANSWER - a signal to which an organism responds
, Polygraph - CORRECT ANSWER - a machine that writes down many different changes in
the body while the person answers questions; a lie detector test
Heart Rate - CORRECT ANSWER - The number of times the heart beats per minute
vital signs - CORRECT ANSWER - A group of the six crucial medical signs that indicate
the status of the body's vital functions.
Pulse - CORRECT ANSWER - The rhythmic expansion and recoil of arteries resulting
from heart contraction; can be felt from the outside of the body.
Respiratory Rate - CORRECT ANSWER - The rate of which breathing occurs
blood pressure - CORRECT ANSWER - the pressure that is exerted by the blood against
the walls of blood vessels
Skin Conductivity - CORRECT ANSWER - How the amount of sweat produced impacts
the ability to conduct electricity
Control Group - CORRECT ANSWER - In an experiment, the group that is not exposed to
the treatment; contrasts with the experimental group and serves as a comparison for evaluating
the effect of the treatment.
experimental group - CORRECT ANSWER - In an experiment, the group that is exposed
to the treatment, that is, to one version of the independent variable.
independent variable - CORRECT ANSWER - The experimental factor that is
manipulated; the variable whose effect is being studied.
Hypothesis - CORRECT ANSWER - A testable prediction, often implied by a theory
