Pbs final exam review questions with
correct answers
Independant variable - 🔷ANSWERS 🖊✔✔The variable that is varied or manipulated by the researcher
Forensic science - 🔷ANSWERS 🖊✔✔The application of scientific knowledge to questions of civil and
criminal law
Biomedical science - 🔷ANSWERS 🖊✔✔The application of the principles of the natural sciences,
especially biology an physiology, to clinical medicine
Control group - 🔷ANSWERS 🖊✔✔The group in an experiment where the independent variable is
being tested is not applied do that it may serve as a standard for comparison against the experimental
group where the independent variable is applied
Personal protective equipment
(P.p.e.) - 🔷ANSWERS 🖊✔✔Specialized clothing or equipment, worn by an employee for protection
against infectious materials (as defined by OSHA)
Experiment - 🔷ANSWERS 🖊✔✔A research study conducted to determine the effect that one variable
has upon another variable.
Positive control - 🔷ANSWERS 🖊✔✔Group expected to have a positive result, allowing the researcher
to show that the experimental set up was capable of producing results
Negative control - 🔷ANSWERS 🖊✔✔Control group where the 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

Compound - 🔷ANSWERS 🖊✔✔A substance consisting of two or more elements in a fixed ratio
Disaccharide - 🔷ANSWERS 🖊✔✔Double sugar molecule made of two monosaccharides bonded
together through dehydration synthesis
Element - 🔷ANSWERS 🖊✔✔Smallest particle of a substance that retains all the properties of the
substance and is composed of one or more atoms
ATP - 🔷ANSWERS 🖊✔✔Adenosine tri phosphate
Dehydration synthesis - 🔷ANSWERS 🖊✔✔Reaction to which two water molecules are bonded
together with the removal of a water molecule
Amino acid - 🔷ANSWERS 🖊✔✔Organic monomer which serves as a building block of proteins
Polysaccharide - 🔷ANSWERS 🖊✔✔Polymer of thousands of thousands of simple sugars formed by
dehydration synthesis
Covalent bond - 🔷ANSWERS 🖊✔✔Strong chemical bond in which two atoms share one or more pairs
of valence electrons
Carbohydrate - 🔷ANSWERS 🖊✔✔Sugar in the form of a monosaccharide, disaccharide or
polysaccharide
Ionic bond - 🔷ANSWERS 🖊✔✔Chemical bond resulting from the attraction between oppositely
charged ions
Monosaccharide - 🔷ANSWERS 🖊✔✔Single sugar molecule such as glucose or fructose, the simplest
type of sugar
