Question

Why would someone compare the inside of a living bone to a subway system?

(a) To highlight the similarities in their structural networks.
(b) To emphasize the differences between organic and inorganic systems.
(c) To explain how bones transport nutrients and waste.
(d) To describe the challenges in maintaining both systems efficiently.

Answer 1

Someone might compare the inside of a living bone to a subway system to illustrate the bone's network of canals and vessels that transport nutrients and waste, similar to how a subway transports people and goods.

Step-by-step explanation:

The comparison between the inside of a living bone and a subway system is most accurately made to illustrate how bones, like a transportation system, deliver necessary substances throughout their structure. This is because living bones contain a network of canals and vessels through which nutrients and wastes are transported, much like a subway system moves people and goods across various destinations. In this case, the correct answer to the student's question is (c) To explain how bones transport nutrients and waste. Similar to the circulatory system's role in transporting oxygen, nutrients, and removing waste products from the body, the bones play an active part in maintaining homeostasis by distributing essential minerals and also engaging in the formation of blood cells.
