BSC1005 MIDTERM EXAM
Comprehensive Practice – 2026/2027 EDITION
100 Questions (Comprehensive) 8 Curriculum Domains Scientific Method to Ecology
Answers & Rationales
I M P O RTA N T N O T I C E
This is an original practice examination built on the general education biology
curriculum — the nature of science and the scientific method, cell and molecular biology,
genetics and inheritance, evolution and natural selection, ecology and behavior, taxonomy
and classification, and human biology and disease. It is not the actual BSC1005 midterm
examination, is not affiliated with or endorsed by Miami Dade College, and contains no
proprietary exam items. Course content varies by instructor and term; your syllabus,
lectures, and assigned materials always control what you are responsible for. It is intended
for self-study and preparation only.
HOW TO USE THIS EXAM
Sit all 100 questions in one timed session to build midterm readiness. Correct answers are
marked [CORRECT] with a rationale addressing the distractors — cover the marked line
to self-test. Five case-study blocks (shaded boxes) present unfolding scientific scenarios
with linked interpretation items. Domains span the scientific method through integrated
multi-topic scenarios, mirroring a comprehensive midterm's reach.

Section 1: The Nature of Science & Scientific Method – Definition of
Biology, Scientific Method, Inquiry, Emergent Properties (15
questions)
Q1: Biology is defined as:
A. The scientific study of life [CORRECT]
B. The study of rocks and minerals
C. The art of classifying stars
D. The study of ancient languages
Correct Answer: A
Rationale: Biology is literally the scientific study of living things; rocks (geology), stars (astronomy), and
languages (linguistics) belong to other disciplines.
Q2: Which of the following is NOT a property shared by all living organisms?
A. Ability to think rationally [CORRECT]
B. Order and organization
C. Growth and reproduction
D. Energy processing (metabolism)
Correct Answer: A
Rationale: All life shows order, reproduction, growth, and energy processing, but rational thought is not
universal — bacteria and plants are alive without it; the other options are core life properties.
Q3: Which list presents the proper components of the scientific method in order?
A. Conclusion → Guess → Publication → Belief
B. Observation → Question → Hypothesis → Prediction → Experiment → Results → Conclusion
[CORRECT]
C. Experiment → Opinion → Observation
D. Hypothesis → Faith → Proof
Correct Answer: B
Rationale: The scientific method flows from observation through question, testable hypothesis,
prediction, experiment, results, and conclusion; the other sequences scramble or omit essential steps.
Q4: A hypothesis is best described as:
A. A proven law of nature
B. A tentative, testable explanation for an observation [CORRECT]
C. A random guess that cannot be tested
D. A personal belief immune to evidence
Correct Answer: B
Rationale: Hypotheses are provisional explanations that generate testable predictions; they are neither
proven laws nor untestable opinions.

Q5: A student proposes, "Bacteria cause this plant disease, so treating seeds with antibiotic will reduce
infection." This statement functions as a:
A. Conclusion
B. Prediction flowing from the hypothesis [CORRECT]
C. Observation
D. Theory
Correct Answer: B
Rationale: The "if...then" style statement predicts experimental outcomes from the hypothesis; it is not
yet an observation, a proven conclusion, or a broad theory.
Q6: For a hypothesis to be scientific, it must be:
A. Popular with students
B. Testable and falsifiable by evidence [CORRECT]
C. Impossible to disprove
D. Approved by a vote
Correct Answer: B
Rationale: Scientific claims must be capable of being tested — and potentially shown false; unfalsifiable
ideas lie outside science regardless of popularity.
Q7: In an experiment testing fertilizer effects on plant growth, the group of plants receiving NO
fertilizer serves as the:
A. Experimental group
B. Control group [CORRECT]
C. Dependent variable
D. Conclusive group
Correct Answer: B
Rationale: The control group (no fertilizer) provides the baseline for comparison; the fertilized plants are
the experimental group, and variables are measured quantities, not groups.
Q8: In the same fertilizer experiment, plant height after 30 days is the:
A. Independent variable
B. Control
C. Dependent variable — the measured outcome [CORRECT]
D. Hypothesis
Correct Answer: C
Rationale: Plant height depends on the manipulated factor (fertilizer), making it the dependent variable;
fertilizer amount is the independent variable, and the hypothesis is the explanation being tested.
