UArk POB Lab Midterm Review {LATEST
2026 -2027 update} QUESTIONS AND
ANSWERS 100% CORRECT
The louder calls stimulate the female to orient to the loud male, ignoring quieter
males. - correct answer the louder calls stimulate the female to orient to the loud
male, ignoring quieter males.
By the end of the experiment half of our pillbugs were on the sand side and half were
on the cornstarch side. We should __________.
Accept both alternative hypotheses
Reject the null hypothesis
Accept one of the alternative hypothesis
Fail to reject the null hypothesis - correct answer fail to reject the null hypothesis
,The pillbugs were clearly trying to get away from the cedar chips. They were clearly
orienting themselves away from the cedar chips and moving toward the furthest part
of the other chamber. This is an example of kinesis.
True or False - correct answer False
What would be problematic about making one side of the sowbug/pillbug chamber hot
and dark while the other side is cool and illuminated?
The bugs might actually prefer light environments but dislike cool environments.
You are comparing more than one difference simultaneously.
There would be confounding variables.
All given choices are correct - correct answer All given choices are correct.
What was the independent variable for the student designed experiment in Lab 2?
, Temperature
Thickness of paper towel layer
Number of pillbugs present
Substrate - correct answer substrate
Which of the following should be included with a graph/figure? Check all that apply.
Axis labels
Units indicated for each axis
Regularly marked axis intervals
A figure caption describing what is depicted - correct answer All are correct.
If sowbugs/pillbugs moved back and forth between the experimental chamber
compartments but averaged 5 on either side
Consistently throughout the observational period, you would retain the null hypothesis.
True or False - correct answer True
