Name:_______________________________ Period:_____ PRACTICE QUESTIONS FOR SECOND NINE WEEKS FINAL TEST Directions: Use your notes from the second nine weeks (Chemistry of Life, Active & Passive Transport, Circulatory System, and Blood Notes) to find the answers to these questions. Function/Definition/List Answer: Cell membranes allow some molecules into and out of a cell but not others, this is called… Answer: Which type of cell transport requires the cell to use energy? Answer: 1.________ List these three states of matter, slowest 2.___________________ 3.________ Answer: liquid, gas, solid, in order from the slowest moving molecules to the fastest moving molecules. ____fastest When there is a high concentration of molecules in one area and a low concentration of the same molecules in another area, a ________________ is created. Answer: Which type of cell transport does not require the cell to use energy? Function/Definition/List Answer: Type of blood vessel that only carries blood away from the heart. Answer: Type of blood vessel that only carries blood toward the heart. Answer: Process that causes molecules to move from an area of high concentration to an area of low concentration. Answer: Process that causes water molecules to move from an area of high concentration to an area of low concentration. Function Answer: Carries oxygen to body cells and takes some carbon dioxide away from body cells. Answer: Helps create blood clots to prevent loss of blood from a cut. Answer: Carries nutrients and hormones to body cells, takes wastes, including some carbon dioxide, away from body cells, helps create blood clots. Answer: Fight invading organisms (bacteria, virus, fungus) and clears the blood stream of debris. Answer: Which type of blood cell needs to have a nucleus?
