BIO 181 ASU CAPCO EXAM 1 ACTUAL
ASSESSMENT PAPER 2026 COMPLETE
QUESTIONS AND SOLUTIONS GRADED A+
◉ observation
Answer: act of viewing the world around us
◉ question
Answer: made based off of an observation
◉ hypothesis
Answer: a tentative explanation for an observation
◉ controlled experiment
Answer: - test several groups
- introduce a single variable per treatment
- keep conditions as similar as possible from one group to the next
◉ conclusion
Answer: supports/refutes hypothesis
,- more experimentation needed if refuted
◉ prediction
Answer: a guess of what might happen based on observation-- the
outcome you would observe if your hypothesis was supported
◉ theory
Answer: a sound explanation of the world supported through
continued observation and experiments over a long period of time
◉ 3 components of a controlled experiment
Answer: 1. variable
2. test group
3. control group
◉ variable
Answer: feature of an experiment that is changed from one
treatment to the next
◉ test group
Answer: exposed to variable in an experiment
, ◉ control group
Answer: not exposed to the variable in an experiment
◉ importance of test group & control group
Answer: they allow researchers to determine whether the variable
in an experiment has an effect
◉ independent variable
Answer: manipulation performed on the test group
(ex. hours of tutoring)
◉ which axis is the independent variable found on a graph?
Answer: x-axis
◉ dependent variable
Answer: effect that is being measured
(ex. test score)
◉ which axis is the dependent variable found on a graph?
Answer: y-axis
◉ theory of evolution
