WSU BIO 102 EXAM 1 STUDY GUIDE
QUESTIONS & ANSWERS(RATED A+)
hypothesis - ANSWERan informed, logical, and plausible explanation of
observations of the natural world
scientific method list - ANSWER1. 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? - ANSWERaccept,
reject, or modify your hypothesis, predictions, or test according to the results
3 hypotheses researchers proposed to explain the bats death - ANSWERif WNS is
caused by a transmissible fungus, then healthy bats that hibernate in contact with
affected bats should develop the condition.
what does it mean that a hypothesis must be "falsifiable" - ANSWERit must make
predictions that can be clearly determined to be true or false, right or wrong
correlation - ANSWERa statistical relation indicating that two or more aspects of the
natural world behave in an interrelated manner
causation - ANSWERa change in one aspect of the natural world causes a change in
another aspect
independent variable - ANSWERvariable that is manipulated by the investigator
dependent variable - ANSWERvariable that can potentially respond to the changes
in the independent variable
control group - ANSWERgroup maintained under a set of standard conditions with
no change in the independent variable
treatment group - ANSWERgroup maintained under the same set of conditions as
the control group, but the independent variable is manipulated
peer review - ANSWERa mechanism used for policing personal or group bias and
even outright fraud in science
what role does peer review play in the scientific process - ANSWERa way for
scientists to receive review and input from other scientists on their results
scientific fact - ANSWERa direct and repeatable observation of any aspect of the
natural world
, scientific theory - ANSWERmajor idea that has been supported by many
observations and experiments
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? - ANSWERWNS was not
airborne, but all who came in contact with the white nose fungus developed WNS
what are the benefits of vaccines - ANSWERvaccines 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 - ANSWERshe
had read that they may cause autism.
what are some ways to access quality sources as you do basic research on a
scientific topic - ANSWERcheck credentials and review primary and secondary
literature
what is pseudo- science - ANSWERscientific sounding statements, beliefs, or
practices that are not actually based on scientific method
what aspects of the autism- vaccination study did not live up to good science
standards - ANSWERstudy was small (only 12 kids), conclusions were grand stating
that children should stop getting the MMR vaccine, had no control group, couldn't be
replicated
what nonscientific aspects might play a role in making life choices - ANSWERyour
values, ethical stances, religious beliefs
what was the problem that both soto and sonnenschein at tufts university and hunt at
case western encountered with the cells they were growing as part of their
experiments? - ANSWERin both cases, something was interfering with the ability of
the cells to divide. for soto and sonnenschein their breast cells were under these
incorrect circumstances, and for hunt, the mouse oocytes were not producing eggs
correctly
at what point does nonylphenol exert its influence - ANSWERduring cell division
whats the difference between a benign tumor and a cancerous (malignant) tumor -
ANSWERa benign tumor is a tumor that is confined to a specific site or area. a
cancerous or malignant tumor is a tumor that breaks away from their initial site and
enters the blood stream or the lymph vessels to emerge in distant locations
throughout the body where they form new tumors
