My definition of Homeostasis "Homeostasis is maintaining equilibrium between the internal and external environment, through processes such as osmosis and diffusion."
 * __What i remember about HOMEOSTASIS__**


 * Osmosis-** Net movement of water molecules from a region of a higher water potential to a region of lower water potential through a partially permeable membrane.
 * Diffusion-** Net movement of particles from a region of higher concentration to a region of lower concentration

MAINTAINING EQUILIBRIUM


 * Energy is stored in the organization of matter
 * Living organisms use matter and energy to build and maintain body structures
 * Living organisms obtain and process matter and energy- Humans eat to get energy so that our body can function. Our cells need glucose so that the mitochondria can convert it into ATP, for the cell to use.
 * The structure of a molecule always dictates its function.
 * The structure and function of biological living systems obeys the laws of thermodynamics.
 * Communities of organisms depend on the cycling of matter and the flow of energy
 * The constant flow of energy and cycling of matter in the biosphere leads to a balanced or steady state.
 * Energy cannot be created or destroyed!
