Correct answer: B. Kinesis
- A. Positive phototaxis
- B. Kinesis
- C. Negative phototaxis
- D. Luminis
Explanation
Kinesis is a non-directional response to a stimulus, where the rate of movement or activity of an organism changes in response to the intensity of the stimulus, but the direction of movement is not specifically oriented towards or away from the stimulus. An example is the increased activity of woodlice in response to increased humidity, without any specific directional movement towards or away from the humid area.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
