PLTW Biomedical Final UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Biomedical Science - CORRECT ANSWER - Application of the principles of natural
sciences, especially biology and physiology, to clinical medicine.
Experiment - CORRECT ANSWER - A research study conducted to determine the effect
that one variable has upon another variable.
Independent Variable - CORRECT ANSWER - The variable that is varied or manipulated
by the researcher.
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.
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.
Forensic Science - CORRECT ANSWER - The application of scientific knowledge to
questions of civil and criminal law.
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.
Dependent Variable - CORRECT ANSWER - The measurable effect, outcome, or response
in which the research is interested.
, Hypothesis - CORRECT ANSWER - Clear prediction of the anticipated results of an
experiment.
Personal Protective Equiptment - CORRECT ANSWER - Specialized clothing or
equipment, worn by an employee for protection against infectious materials (as defined by
OSHA).
Chromosome - CORRECT ANSWER - Any of the usually linear bodies in the cell nucleus
that contain the genetic material.
Deoxyribonucleic Acid - CORRECT ANSWER - A double-stranded, helical nucleic acid
molecule capable of replicating and determining the inherited structure of a cell's proteins.
Gel Electrophoresis - CORRECT ANSWER - The separation of nucleic acids or proteins,
on the basis of their size and electrical charge, by measuring their rate of movement through an
electrical field in a gel.
Gene - CORRECT ANSWER - A discrete unit of hereditary information consisting of a
specific nucleotide sequence in DNA (or RNA, in some viruses).
Helix - CORRECT ANSWER - Something spiral in form.
Model - CORRECT ANSWER - A simplified version of something complex used, for
example, to analyze and solve problems or make predictions.
Nucleotide - CORRECT ANSWER - A building block of DNA, consisting of a five-carbon
sugar covalently bonded to a nitrogenous base and a phosphate group.
Restriction Enzyme - CORRECT ANSWER - A degradative enzyme that recognizes
specific nucleotide sequences and cuts up DNA.
