The Ever Evolving World of Science — Question 1

Things work because of how different parts or materials interact with each other. For example, in a clock, the gears move to show the time, and in a plant, the roots absorb water to help it grow, glowing of an electric bulb. Our bodies work in a similar way, with each organ having a special role to keep us healthy. Science helps us understand how these parts work together to make things function properly.
