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 number of marbles lined up across the circumference of the earth can be, 
marbles
Explanation :
First we have to calculate the diameter of tiny marble.
r = radius of marble = 0.25 mm
Now we have to calculate the number of marbles can be lined up across the circumference of the earth.
Given:
Circumference of the earth distance = 
conversion used: 
Number of marbles can be lined up = 
marbles
Thus, the number of marbles lined up across the circumference of the earth can be, marbles
From Simplest to Most Complex, it follows this order.

Organisms
Given a sentence and an exmaple about them:
Cells: They are the fundamentals in all living things. They have a nucleus, cytoplasm, and organelles which is all surrounded by a cell membrane. Example: Skin Cells, Blood Cells.
Tissue: It is close to Cells, it consists of the material that animals and plants are made, but it also consists specialized cells and their product. Example: Muscle Tissue, Epithelial Tissue.
Organs: Pretty much a part of the body that specializes in a specific function. Example: Liver, Stomach.
Organ System: This is kind of like Organs, however they are a system of organs that rely on each other, whether it is directly or indirectly. Examples: Muscular System, Circulatory System.
Organelles: These are the parts that makes up what a cell is. Exmaple: Golgi Body, Lysosomes.
Answer:
2 g
Explanation:
Since both sides have to be equal, add together the weight from the left side to get the total of 137
