BIOL 1402 EXAM 1 QUESTIONS AND
ANSWERS 2026
Characteristics of a Scientific Hypothesis -
correct answer ✅testable and falsifiable
Compare and Contrast the terms scientific hypothesis and scientific
theory -
correct answer ✅Hypothesis:
- a proposed explanation for a single observation
- it is testable and falsifiable
Scientific Theory:
- powerful, broad explanation for related observations
- these are based on hypotheses
- supported by research
Inductive Reasoning versus Deductive Reasoning -
correct answer ✅Inductive reasoning: combining specific
observations to general principles (formulating)
Deductive reasoning:
general principle to predict observations (predicting)
,BIOL 1402 EXAM 1 QUESTIONS AND
ANSWERS 2026
Explain why the truth of a hypothesis cannot be proven conclusively
via deductive reasoning. -
correct answer ✅?
Features of a controlled experiment -
correct answer ✅- tests effect of a single variable
- limits possible alternate hypotheses
- the differences in results should be due to treatment
Strategies for minimizing bias when designing experiments -
correct answer ✅Blind studies where participant knowledge is
limited
Double Blind Studies where both researchers and participants
knowledge is limited
Define correlation
Explain the benefits and limitations of using this technique to test
hypotheses -
,BIOL 1402 EXAM 1 QUESTIONS AND

correct answer ✅No
Hypothesis: Vitamin C prevents colds. Why is it impossible to say
that this hypothesis is true? -
correct answer ✅Alternative hypotheses might be possible.
Hypotheses need to be tested with laboratory experiments. (T or F)
