◉ Characteristics of Life. Answer: 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. Answer: the smallest unit that displays all characteristics of
life

smaller units called monomers. (Example -Deoxyrbonucleic Acid
[DNA])
◉ Two main types of cells. Answer: Prokaryotic and Eukaryotic
◉ Prokaryote. Answer: Small and simple, do not have clearly defined
