What’s a good analogy of the immune system

The immune system works like what happens when a prisoner is breaking out of their cell. The Cell Mediated Response in the immune system is when killer t-cells attack any cell that has a pathogen on it. In this analogy, the cell-mediated response is the orders given by the police officer.

Explanation:

D) ribosome

Explanation:

The process that you're seeing is translation (i.e. the process by which an mRNA strand, depicted in the picture, is turned into a polypeptide molecule, labeled "Newly formed molecule" in the diagram). Structure X is a ribosome because ribosomes are the only organelles that do this process of translation. Thus, the answer is D) ribosome.

Hope this helps!
