Question

Which statement could be used as a testable hypothesis for a scientificexperiment?A. If you put a cricket in water, it will be too scared to chirp.B. Does humidity affect how rapidly crickets chirp?C. Crickets are more annoying at night than during the day.OD. If the temperature decreases, then crickets will chirp less.

Answer 1

Answer

D. If the temperature decreases, then crickets will chirp less.

Explanation

A hypothesis is a testable guess about the relationship between two or more variables. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly. Conversely, as the temperature falls, the reaction rates slow, causing the chirping to diminish along with it. Therefore the above statem
