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 smallest unit of an element that retains the properties of that
element?
A. Molecule
B. Atom
C. Proton
D. Electron
Answer: B
Rationale: An atom is the smallest unit of an element that retains its chemical properties. It
consists of protons, neutrons, and electrons.
Q2: The mass number of an atom is determined by the sum of:
A. Protons and electrons
B. Protons and neutrons
C. Neutrons and electrons
D. Electrons only
Answer: B
Rationale: The mass number is the total number of protons and neutrons in the nucleus, which
accounts for nearly all the atom's mass.
Q3: Which of the following is an example of a physical change?
A. Burning wood
B. Rusting iron
C. Melting ice
D. Digesting food
Answer: C
Rationale: Melting ice is a physical change because it involves a phase transition from solid to
liquid without altering the chemical composition of water.
,Q4: In a covalent bond, electrons are transferred from one atom to another. (If false, make the
statement true.)
Answer: FALSE. In a covalent bond, electrons are shared between atoms, not transferred. Ionic
bonds involve electron transfer.
Rationale: Covalent bonds form through electron sharing, while ionic bonds form through
electron transfer.
Q5: Which of the following molecules is nonpolar?
A. H₂O
B. NH₃
C. CH₄
D. HCl
Answer: C
Rationale: Methane (CH₄) has a symmetrical tetrahedral shape with nonpolar C–H bonds,
making the molecule nonpolar overall.
Q6: A solution with a pH of 2 is how many times more acidic than a solution with a pH of 5?
A. 3 times
B. 10 times
C. 100 times
D. 1000 times
Answer: D
Rationale: The pH scale is logarithmic; each unit represents a tenfold change. A difference of 3
pH units equals 10³ = 1000 times more acidic.
Q7: Which of the following is the primary function of nucleic acids?
A. Catalyzing metabolic reactions
B. Storing and transmitting genetic information
C. Providing structural support
D. Serving as a primary energy source
Answer: B
Rationale: Nucleic acids (DNA and RNA) store and transmit genetic information through their
nucleotide sequences.
, Q8: All proteins are enzymes. (If false, make the statement true.)
Answer: FALSE. Not all proteins are enzymes; proteins have many functions including
structural support, transport, signaling, and defense.
Rationale: Enzymes are a subset of proteins that catalyze biochemical reactions.
Q9: The alpha helix and beta-pleated sheet are examples of which level of protein structure?
A. Primary
B. Secondary
C. Tertiary
D. Quaternary
Answer: B
Rationale: Secondary structure refers to local folding patterns such as alpha helices and beta-
pleated sheets, stabilized by hydrogen bonds.
Q10: A ___________ is a lipid molecule that contains a phosphate group and is a major
component of cell membranes.
Answer: phospholipid
Rationale: Phospholipids have a hydrophilic phosphate head and hydrophobic fatty acid tails,
forming the lipid bilayer of cell membranes.
Q11: Which of the following is an example of a polysaccharide?
A. Glucose
B. Fructose
C. Sucrose
D. Glycogen
Answer: D
Rationale: Glycogen is a polysaccharide composed of many glucose units, used for energy
storage in animals.
