Behavioral responses in organisms require communication between..
Allushta [10]

Answer:

Behavioral responses in organisms require communication between cells, organs, organ systems and whole organisms.

Explanation:

Complete question is:

Behavioral responses in organisms require communication between I. cells II. organs III. organ systems IV. whole organisms.

Options for this question:

  • <em>II and IV only.</em>
  • <em>I, II, III, and IV.</em>
  • <em>II, III, and IV only.</em>
  • <em>I, II, and IV only.</em>

The relationship function allows living organisms to respond to various stimuli, which defines their behavior in the face of those stimuli.

The coordination of the response to external and internal stimuli involves the whole organism, from the cellular level to the individual level, so the coordinated response depends on the communication between cells, organs, organ systems and the whole organism (the second option I, II, III and IV).

An external stimulus is received by specific receptors, transmitted through the sensory nerves to the central nervous system, which elaborates a response. This response is conducted to an effector organ so that the individual has an adequate response:

  • Cell: Neuron.
  • Organs: Brain, effector organ.
  • Organ system: central nervous system, muscular or hormonal system.
  • Individual: the specific response affects the whole organism.
