The Size of the Solar System Overview • Become familiar with the scale of the planets vs. their distances. • Get an overview of the solar system. Introduction It is easy to flip to the index of an astronomy textbook to discover that‚ say‚ the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible)‚ however‚ to picture this distance in the human mind. In this exercise‚ we will learn to access the often unpalatable distances encountered in astronomy

These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal environments change too- the build up of carbon dioxide as a result of respiration changes the pH of the tissue fluid‚ and therefore inhibits enzyme activity. Multicellular organisms need to coordinate different organs‚ so this requires a good communication system which will: • Cover the whole body • Enable cells to communicate with each other • Enable specific communication • Enable rapid
