A researcher hypothesizes that mice are also susceptible to WNS when they live in close contact with infected bats. To test this hypothesis, the researcher captures 50 healthy mice and randomly separates them into two groups. One group is housed in an area that contains healthy bats. The other group of mice is housed in an enclosure that contains bats that have WNS. The mice in both groups are monitored for signs of WNS. -Presence or absence of any signs of WNS in the mice.

Scientific understanding can always be challenged, and even changed, with new ways of observing and with different interpretations. For example, new tools and techniques have resulted in new observations and the discovery of additional information. This has resulted in revised ways of understanding how molecules are moved across the plasma membrane of cells. Hence, there is no certainty in science, only degrees of probability (likelihood) and potential for change. In light of this understanding, which of the following statements is MOST meaningful?
