Final answer:
Kinesis is a rapid whole-body movement with a change of direction or velocity in response to a stimulus. Organisms, such as woodlice, exhibit kinesis by increasing or decreasing their speed of movement in response to changes in their environment. Kinesis is an innate behavior that helps organisms adapt to changing stimuli.
Step-by-step explanation:
A rapid whole-body movement with a change of direction or velocity in response to a stimulus is known as kinesis.
For example, woodlice increase their speed of movement when exposed to high or low temperatures as a response to the stimulus of temperature change. This movement, although random, increases the probability that the woodlice spend less time in the unfavorable environment.
Other examples of kinesis include orthokinesis, where an organism increases or decreases its speed of movement in response to a stimulus, and klinokinesis, which involves an increase in turning behaviors. Overall, kinesis is an innate behavior that allows organisms to respond and adapt to changing stimuli.
