PLTW EOC Biomedical Sciences Final
Exam with Correct Solutions 2025-
2026 Updated.
Biomedical Sciences - Answer The application of the principles of the natural sciences,
especially biology and physiology, to clinical medicine.
Processing a Crime Scene - Answer 5 parts include photography, sketch, interview, collect
evidence, and examine/analyze evidence.
Forensic Entomology - Answer The use of insects and bugs to determine when a person died
Livor Mortis - Answer The discoloration of the skin due to the pooling of blood in the
dependent parts of the body following death.
Rigor Mortis - Answer The body becomes rigid after death due muscles tensing up from the
lack of ATP, which typically causes them to relax
Algor Mortis - Answer The temperature lost in a dead body
What is Glaister Equation used for? - Answer The equation used to determine time of death.
What is Glaister Equation? - Answer
Control Group - 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 - Answer The measurable effect, outcome, or response in which the
research is interested
Experiment - Answer A research study conducted to determine the effect that one variable
has upon another variable
Forensic Science - Answer The application of scientific knowledge to questions of civil and
criminal law
, Hypothesis - Answer Clear prediction of the anticipated results of an experiment
Independent Variable - Answer The variable that is varied or manipulated by the researcher
Negative Control - 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 (PPE) - Answer Specialized clothing or equipment, worn by an
employee for protection against infectious materials (as defined by OSHA)
Positive Control - Answer Group expected to have a positive result, allowing the researcher
to show that the experimental setup was capable of being produced
Adenine - Answer A component of nucleic acids that carries hereditary information in DNA
and RNA in cells. Chemically, it is a purine base. Bonds with Thymine.
Chromsome - Answer Any of the usually linear bodies in the cell nucleus that contain the
genetic material.
Cytosine - Answer A component of nucleic acids that carries hereditary information in DNA
and RNA in cells. Chemically, it is a pyrimidine base. Bonds with Guanine.
Deoxyribonucleic Acid (DNA) - Answer A double-stranded, helical nucleic acid molecule
capable of replicating and determining the inherited structure of a cell's proteins.
Gel Electrophoresis - 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 - Answer A discrete unit of hereditary information consisting of a specific nucleotide
sequence in DNA (or RNA, in some viruses
Guanine - Answer A component of nucleic acids that carries hereditary information in DNA
and RNA in cells. Chemically, it is a purine base. Bonds with Cytosine
Helix - Answer Something spiral in form
