There are a large number of different types of body cells. Each type has a certain job and is perfectly built to do it. Cells of the body depend on one another to keep the body working. Some examples of different types of cells include nerve cells, muscle cells, and stem cells. Unlike most cells, stem cells are not specialized for a particular job. However, they can change into specialized cells. Stem cells can divide and replicate many times. Since stem cells are so useful, scientists are studying new ways to use them for medicine.
What concept best describes the interdependence and specialized functions of various types of cells in the human body?
A. Genetic Variation B. Cellular Organization
C. Evolutionary Adaptation D. Molecular Synthesis

H. pylori is a bacterium that lives in the extreme acidic environment of the stomach. These bacteria release an enzyme called urease. This enzyme neutralizes the hydrochloric acid produced in the stomach, allowing the bacteria to survive. When spiral-shaped H. pylori bacteria burrows into the stomach wall, it can cause ulcers and even stomach cancer in humans. According to the Centers for Disease Control and Prevention (CDC), most of the world's population have the bacterium. However, the germs don't cause illness in most individuals.
