Bio 201 Exam 1 UPDATED Exam
Questions and CORRECT Answers
Fact - CORRECT ANSWER - confirmed observation, can change (least impt in science)
Theory - CORRECT ANSWER - well-tested & substantiated explanation, stable but can
change (most impt in science)
Law - CORRECT ANSWER - descriptive generalization about nature, can be used to
make predictions, stable but can change, describe but don't explain
Proof - CORRECT ANSWER - no meaning bc all science is tentative & can't be proven
(in math, proof is possible through logic)
Hypothesis - CORRECT ANSWER - statement that can be falsified. Not a question
Scientific method - CORRECT ANSWER - no such thing as a "scientific method." there
are multiple, different ways of generating evidence-based understanding
Model - CORRECT ANSWER - tool (physical, conceptual, or mathematical) that's used to
advance scientific understanding of phenomenon by user of the tool
Argument (argumentation) - CORRECT ANSWER - use of claims, evidence, reasoning
(CER) to convince others
Pattern - CORRECT ANSWER - observable features of natural world that occur
repeatedly
Scientific explanation - CORRECT ANSWER - causal accounts of WHY smth happens
, Physical models (real world) - CORRECT ANSWER - tangible things to advance
understanding
Conceptual models (virtual) - CORRECT ANSWER - drawings or diagrams used to
advance understanding
Diagram - CORRECT ANSWER - copying smth but doesn't advance understanding
Mathematical models (virtual) - CORRECT ANSWER - uses numerical symbols to
advance understanding
Association study - CORRECT ANSWER - tests for relationships between variables
Comparison study - CORRECT ANSWER - tests for differences in 1+ variables between
2+ conditions/groups
Causation (true) study - CORRECT ANSWER - tests for causal relationship by
randomizing units to 2+ conditions (treatment & control)
Natural experiment - CORRECT ANSWER - test occurs in real world
Backward looking - CORRECT ANSWER - historical explanation to explain a
phenomenon
Downward looking - CORRECT ANSWER - explains how smth functions
Upward looking - CORRECT ANSWER - How does this fit into the big picture?
