Your nervous system is most similar to a cruise ship (option C).

The nervous system is a complex network in the body in charge of:

  • Automatic responses and movements.
  • Voluntary movements.
  • Responses to the world.

This system works due to the action of structures such as:

  • The brain.
  • The spinal cord.
  • The nerves.

Moreover, the nervous system works through the following steps:

  1. A stimulus is received, for example, you accidentally touch a hot surface.
  2. This is taken by the nerves to the brain.
  3. The brain processes the information and sends a response, for example, to move the hand away from the hot surface.

Based on this, the system resembles a cruise ship because signals go from the senses to the brain and then back again similar to a cruise going away and then back to the port.

An iron storage tank is placed in the ocean with no cathodic protection. a. What is the electrolyte in this reaction? b. As the
MariettaO [177]

Answer:

Iron is being oxidized at the anode and water is acting as the electrolyte.

Explanation:

When iron is exposed to oxygen and water , the rusting of iron takes place.

<u>The reaction taking place at anode : Oxidation of iron.</u>

{anode:}\;\text{Fe}(s)\;{\longrightarrow}\;\text{Fe}^{2+}(aq)\;+\;2\text{e}^{-}

The reaction taking place at cathode : Reduction of oxygen in the air.

{cathode:}\;\text{O}_2(g)\;+\;4\text{H}^{+}(aq)\;+\;4\text{e}^{-}\;{\longrightarrow}\;2\text{H}_2\text{O}(l)  

The overall reaction:

{overall:}\;2\text{Fe}(s)\;+\;\text{O}_2(g)\;+\;4\text{H}^{+}(aq)\;{\longrightarrow}\;2\text{Fe}^{2+}(aq)\;+\;2\text{H}_2\text{O}(l)

The rust that is hydrated iron(III) oxide can form iron(II) ions which can react further with oxygen.

4\text{Fe}^{2+}(aq)\;+\;\text{O}_2(g)\;+\;(4\;+\;2x)\;\text{H}_2\text{O}(l)\;{\longrightarrow}\;2\text{Fe}_2\text{O}_3{\cdot}x\text{H}_2\text{O}(s)\;+\;8\text{H}^{+}(aq)

Thus, from the above reactions ,

Iron is being oxidized at the anode and water is acting as the electrolyte.
