Environmental Research
3. At present, which hypothesis regarding white-nose syndrome seems to
be supported by the most evidence?
Non-native hypothesis
4. Which of the following is a scientific hypothesis testable by scientific
methods?
Bats with white-nose syndrome are more likely to die over winter than are
bats that do not have the syndrome.
5. Which of the following articles is MOST likely to be peer-reviewed?
The effect of the eyeless mutation of fruit fly reproduction
6. The fact that the fungus causing white-nose syndrome in the United
States shows little genetic variation indicates to scientists that:

7. True or False: Researchers have rejected the hypothesis that the white-
nose syndrome fungus is opportunistic.
True
, 8. In which of the following places are you LEAST likely to find white-nose
syndrome fungus on a bat?
On its back
9. A hypothesis that generates predictions for which empirical data can be
collected is referred to as ___.
Testable
10. All of the following statements are true EXCEPT:
White-nose syndrome causes death to solitary bats overwintering in attics
11. Which of the following refers to information gathered via
observation of physical phenomena?
Empirical evidence
12. An idea or a prediction that can be rejected by evidence is
considered ___.
Falsifiable
13. True or False: White-nose syndrome affects bats overwintering in
large groups in caves.
True
14. Chytridiomycosis is caused by a ___.
Fungus
15. All of the following predictions are falsifiable EXCEPT:

science works?
,C
17. What is the gray material the researcher is examining in this
photograph?
Bats
18. Which of the following is a reason bats seem much more
susceptible to white-nose syndrome in winter than in summer?
Because the fungus is adapted to cold conditions, it grows better on a cold bat
than a warm bat.

Never
20. Which of the following has historically been MOST likely to die of
chytridiomycosis?
Rabbe’s fringe-limbed tree frog
21. True or False: Bats that live communally run a lower risk of
contracting white-nose syndrome than bats that live alone.
, False
22. If a politician says that climate change is just a theory, he or she
___.
Is implying that scientists are just guessing and that there are many other
possible explanations for current patterns of climate change.
23. Scientists often conduct ___ studies, which examine an issue in
different species or regions, to gain insights about the phenomenon they
are investigating.
Comparative

following EXCEPT:
Rabbe’s fringe-limbed tree frog
25. With regard to white-nose syndrome, the opportunistic
hypothesis states that:

another disease.

lines of evidence, it has been elevated to the status of ___.
Theory
