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:
- A stimulus is received, for example, you accidentally touch a hot surface.
- This is taken by the nerves to the brain.
- 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.

Answer:
The phase transition from a solid to a gas.
Explanation:
Entropy is related to the moles of gases available. The more gaseous moles, the higher the entropy.
<em>Identify the process in which the entropy increases.</em>
- <em>the phase transition from a solid to a gas</em>. YES. There are more gaseous moles available so entropy increases.
- <em>a decrease in the number of moles of a gas during a chemical reaction</em>. NO. This causes a decrease in entropy.
- <em>the phase transition from a liquid to a solid</em>. NO. There is almost no change in the entropy in this process.
- <em>the phase transition from a gas to a liquid</em>. NO. There is a decrease in entropy in this process.
- <em>the phase transition from a gas to a solid</em>. NO. There is a decrease in entropy in this process.
I think the correct answer is c if not it’s d
The molarity of Ba(OH)₂ barium hydroxide solution is 0.41 M.
<h3>What is
Molarity ?</h3>
Molarity (M) is the amount of a substance in a certain volume of solution.
Molarity is defined as the moles of a solute per liters of a solution.
Molarity is also known as the molar concentration of a solution
It can be written as
The given data is
Mass of Ba(OH)₂ = 3 g
Volume of solution = 42.8 ml = 0.0428 l
Molecular weight of Ba(OH)₂ = 171 g
Moles of Ba(OH)₂ = 3/ 171 = 0.0175 moles
Molarity = 0.0175/0.0428
=0.41 M
Therefore the molarity of Ba(OH)₂ is 0.41 M.
