BIOL 101 September 15‚ 2012 Assignment 1 Chapter 1 2. What is Homeostasis‚ and why is it important? Give some examples that show how systems work together to maintain homeostasis? Homeostasis is a term used to describe an internal environment being in a state of constant conditions‚ such as constant temperature‚ pH‚ and etc. It is important because staying at an equilibrium requires the least amount of energy and provides the perfect environment for desired reactions to occur. If at any given

Unit 2 Lesson 3 The kinetic theory of matter explains that matter is made up of particles‚ which are in constant motion resulting in the different states of matter. Matter is made of constantly moving particles‚ which tells us how the matter in solids‚ liquids‚ and gases behaves. When molecules bump into each other‚ they do not gain or lose energy‚ they only transfer it‚ so there is no net energy change (law of the conservation of energy). In a solid‚ molecules vibrate in a fixed position
