Abiotic Non-living Ex. A rock crystal can "grow" in a simple fashion. But rock crystals don't sense or respond to changing environments thus they aren't alive. Biotic living - Be made of materials organized in hierarchical patterns. - Use energy and raw materials to survive. - Sense and respond to changing environments also to maintain homeostasis. - Grow, develop, and reproduce. - Evolving populations Atom Basic unit of matter Molecule a chemical structure consisting of at least...

atom Ans: the smallest particle to which matter can be broken down molecule Ans: substance formed by the chemical bonding of two or more atoms cell Ans: the functional unit of life; all living things are composed of them; the smallest living unit of an organism tissue Ans: a group of cells organized to perform a common function organ Ans: a number of tissues organized to perform a common function population Ans: a single species living in a given area community Ans: all of the org...

Biology - the scientific study of life Characteristics of Life - 1. Be made of materials organized in a hierarchical pattern. 2. Use energy and raw materials to survive 3. Sense and respond to changing environments and maintain internal stability, or homeostasis. 4. Grow, develop, and reproduce. 5. Be part of a population that evolves. The Cell - the smallest unit that displays all characteristics of life Matter - Any substance that has mass and takes up space. All matter can be classifie...
