Biology I Exam #1 Questions with CORRECT Answers
(Grade A+)
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
