					Taxes and Kineses

   Taxes and Kineses are both
    examples of orientation behaviour

   Such behaviours describe how
    mobile organisms position
    themselves and move in response to
    external cues e.g. gravity, chemicals
   Kineses - responces to stimuli by simply
    changing their rate of movement or by
    randomly turning without actually
    orientating to the stimulus

   Taxes – involve orientation and
    movement towards or away from one or
    more stimuli

2. Describe the adaptive value of simple
  orientation behaviours such as kineses?
   Answer
Such simple behaviours allow an animal
 to continue making random orientation
 responses until it is in as environment
 that is favourable to its survival.
Once positioned, the behaviour will cease
 unitl the environment conditions
 change once again.
