The graph shows the results of a famous biological experiment. in the experiment, kettlewell believed that the peppered moth demonstrated how environmental pressures influence evolution. he studied two areas. birmingham was a rural wood, with natural conditions. dorset was an urban, industrial area. the moths use tree trunks to camouflage themselves against birds, which are their major predators. natural gene variations produce a light form of the peppered moth, and a dark form, meaning that they are not equally visible. all but one statement is supported by kettlewell's data. that is question options: dark moths had a survival disadvantage in industrial dorset. light moths had a survival disadvantage in industrial dorset. dark moths had a survival disadvantage in forested birmingham. light moths had a survival advantage in forested birmingham.

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later. when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )
