Which of these is an example of kinesis? select one: a. a flea is more active in a dry environment b. a bird homes in on a familiar wetlands area c. a rabbit runs away from a predator d. none of the answers provided are correct e. a moth is drawn to an electric light at night?

The right option is a. flea is more active in a dry environment

Kinesis is an activity or physical movement of a living cell or an organism in response to a stimulus such as light intensity or humidity. Under kinesis, the response to the stimulus activated by an organism is non-directional.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
