Complete Verified Q&As + Review Guide
Guaranteed Pass | Graded A+ | Geneva College
COURSE OVERVIEW
BIOD 101 is a 4-credit introductory biology course offered through Portage Learning by Geneva
College. The course covers chemical principles, biological chemistry, cellular structure and
function, taxonomy, macromolecules, cellular respiration, genetics, cell signaling, and
microbiology. The laboratory component uses virtual labs and interactive simulations.
Assessment includes module exams, lab exams, and a cumulative final exam.
Exam Format: Module exams contain 25 questions each. Lab exams contain 5 questions
each. The Final Exam contains 30 questions. True/False questions are integrated randomly
throughout and require rewriting false statements to make them true
• What’s Included in This Document:
o Modules 1–6 Exams: Complete question sets paired with detailed answers
covering all core lecture and lab exam concepts.
o Lab Exam Components: Specific questions and answers integrated into the
module blocks reflecting lab procedures and practical metrics.
o Comprehensive Final Exam: Dedicated final exam preparation question bank
covering cumulative course material.
,MODULE 1: Fundamentals of Matter and Biomolecules (25 Questions)
Q1: Which of the following is the first step in the scientific method?
A. Hypothesis
B. Observation
C. Experimentation
D. Conclusion
Answer: B
Rationale: Observation is the initial step where a researcher notices a phenomenon before asking
a question or forming a hypothesis.
Q2: An atom with a different number of neutrons than protons is called a(n):
A. Ion
B. Isotope
C. Molecule
D. Compound
Answer: B
Rationale: Isotopes are variants of a chemical element that differ in neutron number while
retaining the same number of protons.
Q3: The atomic number of an element is determined by the number of neutrons in its nucleus. (If
false, make the statement true.)
Answer: FALSE. The atomic number of an element is determined by the number of protons in
its nucleus.
Rationale: Atomic number equals the number of protons, which defines the element's identity.
Q4: Which subatomic particle has a negative charge?
A. Proton
B. Neutron
C. Electron
D. Ion
Answer: C
Rationale: Electrons are negatively charged and orbit the nucleus in electron shells.
,Q5: A substance consisting of two or more different elements chemically bonded together in a
fixed ratio is called a ___________.
Answer: compound
Rationale: A compound is a distinct substance containing two or more elements in a fixed ratio,
such as H₂O or NaCl.
Q6: Which type of bond is formed by the sharing of electron pairs between atoms?
A. Ionic bond
B. Covalent bond
C. Hydrogen bond
D. Metallic bond
Answer: B
Rationale: Covalent bonds involve the sharing of electron pairs between atoms, creating
molecules such as H₂O.
Q7: Hydrogen bonds are strong covalent bonds that hold atoms together within a water
molecule. (If false, make the statement true.)
Answer: FALSE. Hydrogen bonds are weak intermolecular attractions that occur between a
hydrogen atom and an electronegative atom (such as oxygen or nitrogen).
Rationale: Hydrogen bonds are much weaker than covalent bonds and occur between molecules,
not within them.
Q8: The valence shell of an atom refers to its:
A. Inner shell
B. Outermost shell
C. Nucleus
D. Orbital path of neutrons
Answer: B
Rationale: The valence shell is the outermost electron shell and determines the atom's chemical
reactivity and bonding behavior.
Q9: The pH scale measures:
A. Water content
B. Hydrogen ion concentration
, C. Oxygen availability
D. Temperature
Answer: B
Rationale: pH measures the acidity or alkalinity of a solution based on hydrogen ion [H⁺]
concentration.
Q10: A substance with a pH of 3 is considered:
A. Neutral
B. Acidic
C. Basic
D. A buffer
Answer: B
Rationale: pH values below 7 indicate acidity. A pH of 3 is strongly acidic.
Q11: List the four major classes of biomacromolecules and provide one function of each.
Answer: Carbohydrates – primary energy source; Lipids – energy storage and membrane
structure; Proteins – catalysis (enzymes), structure, and signaling; Nucleic acids – storage and
transmission of genetic information.
Q12: Enzymes are consumed during chemical reactions and must be continuously replaced by
the cell. (If false, make the statement true.)
Answer: FALSE. Enzymes are not consumed during chemical reactions; they act as biological
catalysts and can be used repeatedly.
Rationale: Enzymes lower activation energy and emerge unchanged from the reactions they
catalyze.
Q13: Which level of biological organization is defined as a group of similar cells working
together?
A. Organ
B. Tissue
C. Organelle
D. Population
Answer: B
Rationale: Tissues are groups of cells with a similar structure and function that work together.
