Biology 102 Exam 2 WSU Carloye
hypothesis - CORRECT ANSWER-an informed, logical, and plausible
explanation of observations of the natural world
what does it mean that a hypothesis must be "falsifiable" - CORRECT
ANSWER-it must make predictions that can be clearly determined to be true or
false, right or wrong
correlation - CORRECT ANSWER-a statistical relation indicating that two or
more aspects of the natural world behave in an interrelated manner
causation - CORRECT ANSWER-a change in one aspect of the natural world
causes a change in another aspect
independent variable - CORRECT ANSWER-variable that is manipulated by the
investigator
dependent variable - CORRECT ANSWER-variable that can potentially respond
to the changes in the independent variable
control group - CORRECT ANSWER-group maintained under a set of standard
conditions with no change in the independent variable
treatment group - CORRECT ANSWER-group maintained under the same set of
conditions as the control group, but the independent variable is manipulated
peer review - CORRECT ANSWER-a mechanism used for policing personal or
group bias and even outright fraud in science
what role does peer review play in the scientific process - CORRECT
ANSWER-a way for scientists to receive review and input from other scientists on
their results
scientific fact - CORRECT ANSWER-a direct and repeatable observation of any
aspect of the natural world
, scientific theory - CORRECT ANSWER-major idea that has been supported by
many observations and experiments
scientific method list - CORRECT ANSWER-1. observe and ask questions
2. suggest hypothesis
3. make predictions
4. design tests
5. analyze results
what are 3 conclusions scientists have for interpreting their data? - CORRECT
ANSWER-accept, reject, or modify your hypothesis, predictions, or test according
to the results
3 hypotheses researchers proposed to explain the bats death - CORRECT
ANSWER-if WNS is caused by a transmissible fungus, then healthy bats that
hibernate in contact with affected bats should develop the condition.
if the fungus is secondary to an underlying condition, then the infection will only
occur in bats after the primary underlying condition is present
if an environmental contaminant is the cause, then bats with WNS symptoms will
have elevated levels of that contaminant in their blood or on their skin.
what was the conclusions of the bat deaths experiment? - CORRECT
ANSWER-WNS was not airborne, but all who came in contact with the white
nose fungus developed WNS
what are the benefits of vaccines - CORRECT ANSWER-vaccines protect,
especially children, against pathogens such as smallpox and polio. it also
protects against other bacteria that cause disease. these vaccines have gotten
rid of these fatal diseases in the U.S.
what were Anna Eaton's concerns regarding vaccinating her child - CORRECT
ANSWER-she had read that they may cause autism.
