Which term means the basic unit of all living things?

• A. Breach
• B. Therapeutic Effect
• C. Cells
• D. Anaphylaxis

Answer: (C)

The basic unit of life is the cell. In biology, life processes such as metabolism, growth, responding to the environment, and reproduction happen at the cellular level, and every organism is built from cells. A cell can carry out all necessary life functions, and complex organisms are made up of many cells organized into tissues and organs. This idea, known as cell theory, states that all living things are composed of cells and that new cells arise from existing cells. The other terms don’t describe a unit of life—breach relates to breaking something, therapeutic effect refers to how a treatment works, and anaphylaxis is a severe allergic reaction.
