Two test tubes were filled with a solution of bromothymol blue. A student exhaled through a straw into each tube, and the bromothymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. Which statement best explains why the solution in the tube placed in sunlight returned to a blue color?

• Oxygen was produced by photosynthesis.

• Carbon dioxide was removed by photosynthesis.

• Carbon dioxide was produced by respiration.

• Oxygen was removed by respiration.

A potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in the sun and the plant's growth is monitored. Which statement best describes what will most likely happen to the plant over time?

• The plant will grow faster because it is sheltered from the wind.

• The plant will die because it does not have oxygen for photosynthesis.

• The plant will not grow rapidly because carbon dioxide to perform photosynthesis will run out.

• The plant will grow at a slower rate because it requires more water.

Which of the following statements describes cellular respiration?

• Cellular respiration is a chemical process in which the bonds in food molecules and oxygen molecules are broken and new compounds are formed so that energy can be supplied to cells

• Light energy is converted into stored chemical energy

• High-energy sugars and oxygen are formed from carbon dioxide and water

• Usable energy is converted to stored chemical energy for the body to use later
