PLTW Biomedical Science Chapter 1 Test
UPDATED Exam Questions and
CORRECT Answers
biomedical science - CORRECT ANSWER - the application of the principles of the
natural sciences, especially biology and physiology, to clinical medicine
control group - CORRECT ANSWER - the group in an experiment where the independent
variable being tested is not applied so that it may serve as a standard for comparison against the
experimental group where the independent variable is applied
dependent variable - CORRECT ANSWER - the measurable effect, outcome, or response
in which the research is interested
experiment - CORRECT ANSWER - a research study conducted to determine the effect
that one variable has upon another variable
forensic science - CORRECT ANSWER - the application of scientific knowledge to
questions of civil and criminal law
hypothesis - CORRECT ANSWER - clear prediction of the anticipated results of an
experiment
independent variable - CORRECT ANSWER - the variable that is varied or manipulated
by the researcher
negative control - CORRECT ANSWER - control group where conditions produce a
negative outcome. Negative control groups help identify outside influences which may be
present that were not accounted for when the procedure was created.
, personal protective equipment - CORRECT ANSWER - specialized clothing or
equipment, worm by an employee for protection against infectious materials (as defined by
OSHA)
positive control - CORRECT ANSWER - group expected to have a positive result,
allowing the researcher to show that the experimental set up was capable of producing results
what are principles of biomedical science used for? - CORRECT ANSWER - to
investigate the circumstances surrounding a mysterious death
what are experiments designed for? - CORRECT ANSWER - to provide answers to
testable questions
what can be done at a crime scene of a mysterious death to help reconstruct what happened? -
CORRECT ANSWER - collect evidence, interview, examine, sketch, photograph, DNA
sample, witnesses, finger prints, etc. recreate scene
How do the clues found at a scene of a mysterious death help investigators determine what might
have occurred and help identify or exonerate potential suspects? - CORRECT ANSWER -
they might be able to tell them who was at the scene, wounds on victim, run DNA on fingerprints
or blood
How do scientists design experiments to find the most accurate answer to the question they are
asking? - CORRECT ANSWER - scientific method:problem, hypothesis, design
experiment, procedure, analyze data, chart, conclusion,summary, next steps
How are bloodstain patterns left at a crime scene used to help investigators establish the events
that took place during a crime? - CORRECT ANSWER - they show which angle and
height the blood was dropped from, they help determine what happened at the scene, like
violence of death
crime scene search methods - CORRECT ANSWER - link: no set pattern, evidence leads
to where they go next
