10. Explain why this diagram represents passive transport.

11. high low Weeee!!! Explain why this diagram represents passive transport.

12. HIGH LOW + energy 1.Identify the high and low concentration. 2.Identify the type of transport occurring. Support your answer.

13. Active Transport Movement of materials from LOW  HIGH concentration ENERGY IS NEEDED!

20. Exit Card… Compare and contrast passive and active transport by completing one of the following. Write a paragraph of at least 4 sentences comparing and contrasting passive and active transport. Be sure to use the following terms: particles, energy, high concentration, low concentration. OR Compare and contrast passive and active transport by drawing diagrams of each type. Be sure to label the particles, high concentration, low concentration, energy. Draw an arrow showing the movement of the particles.

50. TRUE OR FALSE 1. Respiration is when structures and organs move oxygen into the body and waste gases out of the body. 2. Breathing can help respiration when its waste gases move out of the body. 3. Respiration is the chemical reaction that happens when oxygen delivered to the cells is used to release energy from glucose.

51. 4. So when you breathe out you are using cell respiration. 5. Respiration spreads necessary items into cells that need it. 6. Breathing is the movement of the chest that brings air into the lungs and removes gas. 7. Respiration is the process when CO 2 and H 2 O molecules are carried back to the lungs in the blood.
