Answer:
If a contaminant is the cause of death, then exposure of bats to the contaminant will lead to illness and death.
If a contaminant is the cause of death, then contaminants will be detected or measured in the cave or in the bats.
Explanation:
A hypothesis can be described as a tentative experiment which can either be proved to be right or wrong through experiments.
Through the above-stated hypothesis, one of the predictions that scientists might make is that if a pesticide was actually the reason for the death of the bats, then exposure to this pesticide should cause death in the bats in a lab.
Also, to determine the cause of death, the pesticide needs to be detected in the bats.
