BIO 181 QUIZ 1 GENETICS AND
INHERITANCE BASIC CONCEPTS PRACTICE
EXAM ITEMS ANSWERS DNA AND
HEREDITY REVIEW 2026
◉ inductive reasoning
Answer: generalization that summarizes many concurrent
observations
◉ Scientific Method
Answer: Observation, Hypothesis (test it, then make prediction.. this
is deductive reasoning),
Experiment,
Analysis,
Conclusion,
Communicate Results
◉ What is good science?
Answer: -more than one hypothesis (therefore not biased in favor of
one idea)
,◉ What makes a good experiment?
Answer: -quantifiable and reproducible data
-appropriate experimental subjects
-proper controls
-verified by others
◉ What makes an experiment unethical?
Answer: -change data to better fit a hypothesis (like falsifed or
created data)
◉ controlled experiment
Answer: -all environmental variables constant and included at least
two groups
-control group-> does not recieve experimental treatment, helps
ensure results obtained are due to a difference in one variable
-experimental group-> recieves the experimental treatment
◉ What if there is no control group?
Answer: There is no basis for knowing if a particular result is due to
the variable being tested or to some other factor
◉ Biological Organization
, Answer: 1. biosphere, 2.ecosystem, 3.community, 4.population,
5.organism,
6.organ system organ, 7.tissue,
8.cell,
9.organelle,
10.molecule
◉ Biological Organization is a hierarchy of which structural levels
Answer: molecule
cell
organ system
population
ecosystem
biosphere
◉ What determines function?
Answer: structure
◉ What does structure determine?
Answer: function
◉ Classification
