Option (III) .Cephalization, the clustering of neurons and interneurons in the anterior part of the animal, is apparent in <u>Planaria.</u>

What is planaria?

  • Planaria is a genus of planarians in the family Planariidae.
  • When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
  • Currently the genus Planaria is defined as freshwater triclads with oviducts that unite to form a common oviduct without embracing the bursa copulatrix and with an adenodactyl present in the male atrium.
  • The testes occur along the whole body.
  • Planaria originally have habitats in dark, murky water which results in such sensitivity .
  • They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields .
  • Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx).

Nataliya [291]

Answer:

subliminal perception.

Explanation:

Subliminal perceptions, also known as subliminal messages, are messages, either visual or auditory, that are presented just beyond the threshold of human perception. A subliminal perception may not be audible enough that the conscious mind might register it but be audible enough for the subconscious mind.

For example it might be an image transmitted briefly and unperceived consciously and yet perceived unconsciously.
