  6. Living Thing = Organism • 5 Characteristics: • Cells & DNA • Reproduce • Grow & Develop • Homeostasis • Adapt

  7. In depth explanation of 5 characteristcs of living things: • 1. Cells & DNA • Cell- Basic unit of life • DNA- Genetic info • 2. Reproduce • To further species Species- a group of similar organisms that can interbreed and have fertile offspring.

  8. Liger & Zonkey

  9. (con’t) Grow Develop • 3. • 4. Homeostasis • *Internal balance • Ex. Sweating, dogs panting. • Without it you will die! Become larger. Mature; become like an adult.
