A) decrease

B) increase

C) stay the same

2. If you double the air temp. the chirp rate will

A) double

B) be halved

C) remain the same

D) all of the above

3. Assume that the cricket is chirping at a rate of 148 chirps/minute and slows to a rate of 10 chirps/minute. Could this change in behavior be explained by either an increase in the temp or a drop in the wind speed?

A) yes

B) no

4. Could this change in behavior be explained by both the air pressure and the humidity increasing?

A) yes

B) no

5. Could a drop in the number of crickets nearby and an Increase in humidity have caused this change in behavior?

A) yes

B) no

    1. B) Increase. If you increase the air temperature, a cricket's chirp rate will B) increase.

    2. E) none of the above.

    The graph of chirp rate vs temperature is a straight line. It does not go through the origin, so the relationship is not a direct proportion. The chirp rate will increase, but it will not double.

    3. B) No. Increasing the temperature increases the chirp rate and wind speed has no effect on the chirp rate.

    4. B) No. Neither air pressure nor humidity affects the chirp rate.

    5. B) No. Neither the number of neighbours nor the humidity affects the chirp rate.
