INTRODUCTION
BIOL 1010 – A Survey of Life is a foundational, comprehensive introductory biology course
offered at the collegiate level, designed to provide students with a broad overview of the
principles governing life on Earth. This course serves as a gateway for students majoring in
biology, health sciences, environmental science, and other related fields, as well as fulfilling
general education requirements for non-majors. The curriculum covers the entire spectrum
of biological organization, from the molecular building blocks of life to the complex
interactions within ecosystems. Topics include the chemical basis of life, cellular structure
and function, genetics and inheritance, evolution and natural selection, the diversity of life
(from prokaryotes to eukaryotes), plant and animal form and function, and ecological
principles. This exam is a critical assessment, evaluating a student's ability to synthesize
concepts across all levels of biological organization and apply them to real-world scenarios.
This comprehensive question bank has been meticulously crafted to mirror the difficulty,
application-level thinking, and content breadth of the actual BIOL 1010 exams. By working
through these 200 advanced, scenario-based questions, you will not only solidify your
foundational knowledge of biology but also master the nuanced analytical skills required to
excel in this demanding course and pass on your very first attempt.
CORE DOMAINS TESTED
The BIOL 1010 exam evaluates candidates across a broad spectrum of knowledge areas
essential for a foundational understanding of life. Based on the official course description
and standard curriculum, the core domains tested include:
1. The Chemical Basis of Life: This domain covers the fundamental chemistry of life,
including atoms, molecules, water properties, pH, organic molecules (carbohydrates,
lipids, proteins, nucleic acids), and the role of enzymes in biological reactions.
2. Cell Structure and Function: This area tests knowledge of prokaryotic and eukaryotic
cell structure, including organelles (nucleus, mitochondria, chloroplasts, endoplasmic
reticulum, Golgi apparatus), the plasma membrane, cellular transport mechanisms,
and the differences between plant and animal cells.
3. Cellular Energetics: This domain focuses on energy transformations in cells, including
metabolism, enzymes, ATP, photosynthesis (light reactions and Calvin cycle), and
cellular respiration (glycolysis, Krebs cycle, electron transport chain).
4. Genetics and Molecular Biology: This section covers DNA structure and replication,
gene expression (transcription and translation), Mendelian genetics, patterns of
inheritance, mutations, and biotechnology applications.

5. Evolution and Natural Selection: This domain covers the principles of evolution,
including Darwinian natural selection, evidence for evolution, population genetics,
speciation, and the history of life on Earth.
6. Diversity of Life: This area explores the major groups of organisms, including
bacteria, archaea, protists, fungi, plants, and animals, with a focus on their
evolutionary relationships, key characteristics, and ecological roles.
7. Plant and Animal Form and Function: This domain covers the anatomy and
physiology of plants (transport, reproduction) and animals (digestion, circulation,
respiration, excretion, nervous system, immune system).
8. Ecology: This section applies biological principles to the study of interactions
between organisms and their environment, including population ecology, community
ecology, ecosystem ecology, and conservation biology.

Q1: A newly discovered unicellular organism is found to have a
nucleus, mitochondria, and chloroplasts. Based on this information,
this organism is most accurately classified as:
A) A prokaryote
B) A eukaryotic autotroph
C) A eukaryotic heterotroph
D) An archaeon
Rationale: The correct answer is B. The presence of a nucleus and
mitochondria indicates it is a eukaryote. The presence of chloroplasts
indicates it is capable of photosynthesis, making it an autotroph.
Option A is incorrect because prokaryotes lack a nucleus and
membrane-bound organelles. Option C is incorrect because
heterotrophs cannot photosynthesize. Option D is incorrect because
archaea are prokaryotes.
Q2: A researcher is studying the effect of pH on the activity of a
digestive enzyme. She finds that the enzyme is most active at pH 2
and becomes inactive at pH 7. This enzyme is most likely found in
which part of the human digestive system?
A) The mouth
B) The small intestine
C) The stomach
D) The large intestine
Rationale: The correct answer is C. The stomach has a highly acidic
environment (pH ~2) due to gastric acid, which is the optimal pH for
pepsin and other stomach enzymes. Option A is incorrect because the
mouth has a neutral pH. Option B is incorrect because the small
intestine has a basic pH. Option D is incorrect because the large
intestine has a neutral pH.

Q3: A mutation occurs in a gene that codes for a protein. The
mutation changes a single nucleotide in the DNA sequence, but the
resulting protein is completely normal. This is most likely due to:
A) A frameshift mutation
B) The redundancy of the genetic code (degeneracy)
C) A nonsense mutation
D) A missense mutation
Rationale: The correct answer is B. The genetic code is redundant,
meaning that multiple codons can code for the same amino acid. If
the mutation results in a codon that codes for the same amino acid (a
silent mutation), the protein will be normal. Option A is incorrect
because a frameshift mutation changes the reading frame and
typically results in a non-functional protein. Option C is incorrect
because a nonsense mutation creates a stop codon, resulting in a
truncated protein. Option D is incorrect because a missense mutation
changes one amino acid, which can affect protein function.
Q4: A plant cell is placed in a hypertonic solution. Which of the
following will most likely occur?
A) The cell will swell and burst.
B) Plasmolysis will occur as water leaves the cell.
C) The cell will remain unchanged.
D) Turgor pressure will increase.
Rationale: The correct answer is B. In a hypertonic solution, the
concentration of solutes outside the cell is higher than inside. Water
will move out of the cell via osmosis, causing the cell membrane to
shrink away from the cell wall (plasmolysis). Option A is incorrect
because that occurs in a hypotonic solution. Option C is incorrect
because water will move. Option D is incorrect because turgor
pressure will decrease.
