Elijah wants to test the effect of carbon dioxide on rates of photosynthesis in radishes. He will keep the water, carbon dioxide, fertilizer, and light provided to one group of radishes constant and compare the growth of these radishes with a second group of radishes.

 

What conditions should Elijah use for the second group of radishes?

• He should keep the conditions consistent with the first group.

• He should keep the amounts of water, fertilizer, and light consistent with the first group while varying the amount of carbon dioxide.

• He should vary the amounts of light, fertilizer, and carbon dioxide while keeping the amount of water consistent with the first group.

• He should vary the amounts of water and fertilizer while keeping the amounts of light and carbon dioxide consistent with the first group.

Tony spaces 5 plants apart equally along a line, with the first plant directly in front of a window and the last plant 30 feet away from the window. He gives them equal access to air and water and then monitors the amount of gas each plant releases.

 

Which gas is Tony monitoring and what trend is he most likely to see in the data he collects?

• He is monitoring oxygen. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.

• He is monitoring carbon dioxide. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.

• He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.

• He is monitoring carbon dioxide. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.

One living plant leaf, still attached to the plant, is placed into a cup and covered with water. A light source is placed above the cup shining into the cup of water so that the leaf receives the light. In moments, bubbles appear at the surface of the plant leaf.

Which statement explains what causes the bubbles to appear?

• Photosynthesis is occurring and bubbles of carbon dioxide gas are being released by the surrounding area and absorbed into the plant leaf.

• Photosynthesis is occurring and bubbles of carbon dioxide gas are being released by the leaf into the surrounding area.

• Photosynthesis is occurring and bubbles of oxygen gas are being released into the surrounding area.

• Photosynthesis is occurring and bubbles of air are entering the water from the area around the plant.

Margie illustrated the process of photosynthesis, as shown below.

Which mistake did she make?

• The arrow for sugar should point away from the plant.

• The arrow for carbon dioxide should point away from the plant.

• The arrows for carbon dioxide and sugar should point away from the plant.

• The arrow for carbon dioxide should point away from the plant, and the arrow for oxygen should point toward the plant.

Which statement about cellular respiration is true?

• Oxygen is a waste product of cellular respiration in both plants and animals.

• Oxygen is a waste product of cellular respiration in plants, but not in animals.

• Carbon dioxide is a waste product of cellular respiration in both plants and animals.

• Carbon dioxide is a waste product of cellular respiration in plants, but not in animals.

Cellular respiration occurs in the body 24 hours per day. During exercise, the rate of cellular respiration increases. Why does increased cellular respiration cause people to breathe faster?

• More water is lost from the body, and breathing hydrates the body.

• More heat is generated by the body, and breathing cools the body quickly.

• More nutrients are needed to produce more energy, and more oxygen must be removed from the body.

• More oxygen is needed to produce more energy, and more carbon dioxide waste must be removed from the body.

After food is consumed, chemical nutrients are absorbed into the blood. These nutrients then enter mitochondria. Which reaction must occur next for the cell to carry on other activities?

• Glucose and water combine to produce high-energy molecules.

• Glucose and oxygen combine to produce high-energy molecules.

• Oxygen, light, and glucose combine to produce high-energy molecules.

• Oxygen, carbon dioxide, and glucose combine to produce high-energy molecules.

Altitude training is done by many athletes. Athletes travel to areas of high altitudes where there is less oxygen in the air. The body adapts to the stress of less oxygen by getting more efficient at transporting oxygen by red blood cells and using the oxygen needed for cellular respiration. What role of oxygen are athletes who train in altitude trying to enhance?

• energy production

• building of muscle tissue

• pH balance of red blood cells

• enhancement of the immune system

How does cellular respiration directly benefit animals?

• by producing glucose

• by consuming oxygen

• by forming carbon dioxide

• by storing energy in adenosine triphosphate (ATP)
