Which best describes the tongue, ears, and nose?
a)sense organs that are part of the central nervous system
b)sense organs that are part of the peripheral nervous system
c)internal organs that are part of the central nervous system
d)internal organs that are part of the peripheral nervous system

Answer;

B) sense organs that are part of the peripheral nervous system

Explanation;

-The sense organs contain receptors that are sensitive to stimuli.

-The nervous system consists of the central nervous system; brain and spinal cord -and peripheral nerves. Nerve impulses travel through the axons of neurones; nerve cells. Reflex actions are fast, automatic and protective responses.

-Receptors are groups of specialised cells. They can detect changes (stimuli) in the environment. Receptors are often located in the sense organs, such as the ear, eye and skin. Each organ has receptors sensitive to particular kinds of stimulus.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
