Question

Refer to the following graph, which shows the tuning curve of crickets exposed to sounds of from 3 to 100 KHz. The "intensity threshold" on the graph refers to the: Loudest sound of a given sound frequency that a cricket can hear. Softest sound of a given sound frequency that a cricket can hear. Most intense response given by a cricket to a given sound frequency. Least intense response given by a cricket to a given sound frequency, Can crickets most easily hear sound frequencies of_____kHz. 3 5 20 40 The graph does not constitute a scientific conclusion because: It does not contain the prediction that the data were designed to check. It does not answer a causal question of any sort. The data were gathered to test whether a prediction was correct prior to reaching a conclusion. The data were collected from only one cricket and thus are inconclusive, We can best use the graph to demonstrate "stimulus filtering" by pointing to the response of crickets to sounds of_____kHz. 3 5 20 40

Answer 1

(i) b

This intensity is dependent on the time of exposure. If the exposure time is decreased then the intensity goes up by the same factor.

(ii) c

As per the given graph crickets can hear the sounds in the frequency 20 kHz.

(iii) a

No information is given in the graph regarding what is being checked in the experiment.

(iv) b

5 kHz
