Biology I Exam #1 UPDATED Study Guide
QUESTIONS AND CORRECT ANSWERS
- 5 steps of scientific method - CORRECT ANSWERS 1.
observation
2. question
3. hypothesis
4. experiment
5. conclusion
observation - CORRECT ANSWERS act of viewing the world
around us
question - CORRECT ANSWERS made based off of an
observation
hypothesis - CORRECT ANSWERS a tentative explanation for
an observation
controlled experiment - CORRECT ANSWERS - test several
groups
- introduce a single variable per treatment
- keep conditions as similar as possible from one group to the next
conclusion - CORRECT ANSWERS supports/refutes
hypothesis
- more experimentation needed if refuted
,prediction - CORRECT ANSWERS a guess of what might
happen based on observation-- the outcome you would observe if
your hypothesis was supported
theory - CORRECT ANSWERS a sound explanation of the
world supported through continued observation and experiments over
a long period of time
3 components of a controlled experiment - CORRECT ANSWERS
1. variable
2. test group
3. control group
variable - CORRECT ANSWERS feature of an experiment that
is changed from one treatment to the next
test group - CORRECT ANSWERS exposed to variable in an
experiment
control group - CORRECT ANSWERS not exposed to the
variable in an experiment
importance of test group & control group - CORRECT ANSWERS
they allow researchers to determine whether the variable in an
experiment has an effect
, independent variable - CORRECT ANSWERS manipulation
performed on the test group
(ex. hours of tutoring)
which axis is the independent variable found on a graph? -
CORRECT ANSWERS x-axis
dependent variable - CORRECT ANSWERS effect that is
being measured
(ex. test score)
which axis is the dependent variable found on a graph? - CORRECT
ANSWERS y-axis
theory of evolution - CORRECT ANSWERS set of hypotheses
that provide a powerful explanation for both biological observations
& the diversity of life
why do we learn that the theory of evolution is the single most
important theory in all of biology? - CORRECT ANSWERS
there's lots of evidence from asking/testing good scientific
questions
(ex. anatomy, fossil record, biogeography, molecular biology)
7 ways living organisms are different from non-living organisms -
CORRECT ANSWERS 1. organization - complex organization
2. response - ability to change in response to the environment
