scientists are interested in determining if selenium, from a nearby mine, magnifies in the tissues of fish living in a lake. which of the following best describes a testable hypothesis for the study?
A testable hypothesis for the study can be formulated as follows:
Hypothesis: The concentration of selenium in the tissues of fish in the lake will increase with proximity to the nearby mine.
This hypothesis presents a clear relationship between the proximity to the nearby mine and the concentration of selenium in fish tissues. It can be tested by collecting fish samples from different locations in the lake and analyzing the selenium levels in their tissues. By comparing the selenium concentrations in fish from various distances from the mine, the hypothesis can be supported or rejected based on the observed data.
