Orientation behaviour:

Correct answer: A. Kinesis

  • A. Kinesis
  • B. Water retension by kidneys
  • C. Calcitonin
  • D. Sugar in urine

Explanation

Kinesis is a type of orientation. While orientation behavior involves a directed response towards or away from a stimulus, kinesis involves an undirected change in activity level in response to a stimulus. Both mechanisms allow organisms to respond to their environment, but kinesis does not provide a directed movement towards a more favorable environment; rather, it increases the likelihood of encountering such an environment by altering movement speed or turning frequency.

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.
