JMU BIO 140 Lab Exam QUESTIONS
WITH COMPLETE SOLUTIONS
What are the parts of the process of science? Correct Answer: -exploration and
discovery
-testing ideas
-community analysis and feedback
-benefits and outcomes
What occurs during exploration and discovery? Correct Answer: -making
observations
-asking questions
-sharing data and ideas
-finding inspiration
-exploring the literature
What occurs in testing ideas? Correct Answer: -gathering data (hypothesis,
expected results, and actual results)
-Interpreting data (support/oppose hypothesis, inspire new hypothesis, inspire
revised assumptions)
What occurs in benefits and outcomes Correct Answer: -develop technology
-address social issues
-build knowledge
-inform policy
-satisfy curiosity
-solve everyday problems
What occurs in community analysis and feedback? Correct Answer: -feedback and
peer review
-replication
-discussion with colleagues
-publication`
-new questions
-theory building
Define independent variables Correct Answer: the variable that is manipulated in
an experiment
, Define hypothesis Correct Answer: proposed explanation for an observation
Define dependent variable Correct Answer: The measurable effect, outcome, or
response in which the research is interested.
Define control Correct Answer: In an experiment, the standard that is used for
comparison
Define treatment Correct Answer: a specific condition applied to the individuals in
an experiment
Define prediction Correct Answer: A logical statement about what will happen if
the hypothesis is correct.
Define experiment Correct Answer: the act of conducting a controlled test or
investigation
Define non-experimental Correct Answer: observational
Define descriptive study Correct Answer: giving details about; illustrating;
explaining
What are the main flaws in experimental designs? Correct Answer: -no controls
-insufficient sample size
-lack of replication
-not really testing the hypothesis
-important variables not held constant
Heritable features Correct Answer: those that can be passed down from one
generation to the next
Phylogeny Correct Answer: proposed evolutionary relationship that arise from
analyzing heritable traits among organisms
Systematic analysis Correct Answer: helps create classification systems that
convey information about the evolutionary relationship of organisms
Phylogenetic trees Correct Answer: hypothesize lineage of organisms represented
as branching trees
