Answer the following question given this paragraph: You consist of a great many cells, but like all other organisms, you started life as a single cell. How did you develop from a single cell into an organism with trillions of cells? The answer is cell division. After cells grow to their maximum size, they divide into two new cells. These new cells are small at first, but they grow quickly and eventually divide and produce more new cells. This process keeps repeating in a continuous cycle. Q: What process allows an individual to develop from a single cell into an organism with trillions of cells? A:
OPTIONS:
- cell transition
- Cell multiplication
- cell function
- cell division

Answer: cell division

Answer the following question given this paragraph: Glaciers form when more snow falls than melts each year. Over many years, layer upon layer of snow compacts and turns to ice.

Answer the following question given this paragraph: The four-chambered mammalian heart can pump blood in two different directions. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart pumps blood containing oxygen to the rest of the body. Because of the dual pumping action of the heart, all of the blood going to body cells is rich in oxygen. Q: How many chambers does a mammalian heart have? A:
OPTIONS:
- one
- five
- three
- four

Answer:
four
