Question

The universe consists of many different galaxies, which, in turn, consist of many different solar systems. Each solar system has a central star around which planets orbit. Earth, for example, is a planet that orbits the Sun in the Solar System. The Solar System is one of many that can be found in the Milky Way galaxy. This example demonstrates that

A. some systems contain other smaller systems.
B. some systems are a part of larger systems.
C. some systems are connected to other systems.
D. all of these

Answer 1

D: All of these

Explanation

"A system is a group of many simple parts and processes that influence or interact with each other. Some systems are even connected to other systems.

Some systems are a part of larger systems. For example, the solar system is only one part of a larger galaxy system, and a galaxy is only a part of the whole universe.

Some systems contain other smaller systems. For example, the Earth is a subsystem of the solar system. The geologic systems and life systems of the planet Earth are subsystems of the Earth system. And, each of these systems contains smaller systems, as well, such as the system of plate tectonics or a particular ecosystem."
