BIOLOGY I EXAM #1 UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
Question:
1. 5 steps of scientific method
Answer:
1. observation
2. question
3. hypothesis
4. experiment
5. conclusion
Question:
2. observation
Answer:
act of viewing the world around us
Question:
3. question
Answer:
made based off of an observation
Question:
4. hypothesis
Answer:
a tentative explanation for an observation
Question:
5. controlled experiment
Answer:
- test several groups
- introduce a single variable per treatment
- keep conditions as similar as possible from one group to the next
Question:
6. conclusion
Answer:
supports/refutes hypothesis
- more experimentation needed if refuted
,Question:
7. prediction
Answer:
a guess of what might happen based on observation-- the outcome you would
observe if your hypothesis was supported
Question:
8. theory
Answer:
a sound explanation of the world supported through continued observation and
experiments over a long period of time
Question:
9. 3 components of a controlled experiment
Answer:
1. variable
2. test group
3. control group
Question:
10. variable
Answer:
feature of an experiment that is changed from one treatment to the next
Question:
11. test group
Answer:
exposed to variable in an experiment
Question:
12. control group
Answer:
not exposed to the variable in an experiment
Question:
13. importance of test group & control group
Answer:
they allow researchers to determine whether the variable in an experiment has an
effect
, Question:
14. independent variable
Answer:
manipulation performed on the test group
(ex. hours of tutoring)
Question:
15. which axis is the independent variable found on a graph?
Answer:
x-axis
Question:
16. dependent variable
Answer:
effect that is being measured
(ex. test score)
Question:
17. which axis is the dependent variable found on a graph?
Answer:
y-axis
Question:
18. theory of evolution
Answer:
set of hypotheses that provide a powerful explanation for both biological
observations & the diversity of life
Question:
19. why do we learn that the theory of evolution is the single
most important theory in all of biology?
Answer:
there's lots of evidence from asking/testing good scientific questions
(ex. anatomy, fossil record, biogeography, molecular biology)
