UNIT 4 TEST REMEDIATION Q'S

Aria used arrows to represent the gases that enter and leave a plant during the process of photosynthesis, as shown below. Which gases do arrows 1 and 2 represent?

• Arrow 1 is oxygen and arrow 2 is nitrogen.

• Arrow 1 is nitrogen and arrow 2 is oxygen.

• Arrow 1 is oxygen and arrow 2 is carbon dioxide.

• Arrow 1 is carbon dioxide and arrow 2 is oxygen.

In a biology experiment, Sarah places 6 plants in a row, with the first plant positioned right next to a light source and the last plant 12 meters away from it. She ensures all plants receive the same amount of water and nutrients. She then measures the gas emitted by each plant. Which gas is Sarah measuring and what pattern is she likely to observe in her results?

• She is measuring oxygen. The gas emission should be highest for the plant nearest to the light source and lowest for the plant farthest from it.

• She is measuring carbon dioxide. The gas emission should be highest for the plant nearest to the light source and lowest for the plant farthest from it.

• She is measuring oxygen. The gas emission should be highest for the plant in the middle and lowest for the plants at the ends.

• She is measuring carbon dioxide. The gas emission should be highest for the plant in the middle and lowest for the plants at the ends.

Rohan just finished eating his lunch. After the food is consumed, chemical nutrients are absorbed into the blood. The blood then carries these nutrients to the body's cells where the nutrients 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.

Avery is running a marathon and notices that she starts to breathe faster as she continues. Why does increased cellular respiration cause Avery to breathe faster?

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

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

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

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

Aria and Benjamin are studying how living organisms obtain energy. Which statement about cellular respiration in plants and animals is true?

• Both plants and animals need water to start cellular respiration.

• Both plants and animals release energy from glucose in cellular respiration.

• Both plants and animals take in carbon dioxide to break down glucose in cellular respiration.

• Both plants and animals need chlorophyll to make glucose before using it in cellular respiration.

Benjamin, an aspiring marathon runner, decides to train in the mountains where the air is thinner and contains less oxygen. His body adapts to this environment by becoming more efficient at transporting and using oxygen. What is Benjamin most likely trying to enhance through this high-altitude training?

• energy production in the mitochondria

• enhancement of the nervous system

• pH balance of red blood cells

• building of muscle tissue

During a biology class, Alex is asked to explain the carbon cycle. He describes how carbon dioxide from the atmosphere is absorbed by plants, which are then eaten by animals. The animals use the carbon to build their bodies and release carbon dioxide back into the atmosphere through respiration. Which statement below identifies an error in Alex's explanation?

• Animals do not release carbon dioxide; only plants do.

• Animals do not use carbon dioxide directly; they use organic compounds like glucose.

• Plants do not absorb carbon dioxide from the atmosphere; they only absorb it from water.

• Plants do not pass carbon to animals; animals get it directly from the air.

Emma is using clay to create a sculpture. After finishing, she decides to break it down to make something new. Which stage of the carbon cycle does this action best represent?

• carbon atoms being stored in fossil fuels

• plants absorbing carbon dioxide during photosynthesis

• decomposition of organic matter releasing carbon into the soil

• animals incorporating carbon into their bodies

Sophia needs an image to represent the carbon cycle for a presentation in her science class. Based on the information represented in the concept models above, which statement is true?

• Model A would be the best model for the carbon cycle because carbon depletes over time as it is used by different organisms.

• Model B would be the best model for the carbon cycle because carbon will follow the same path when it is transferred from one place to another.

• Model C would be the best model for the carbon cycle because the carbon cycle has a definite beginning and end where carbon eventually cannot be reused.

• Model D would be the best model for the carbon cycle because the carbon cycle is a flow of matter which can take different paths bringing carbon back to the same place.

In a diagram of the carbon cycle, what role do herbivores play in the movement of carbon?

• Herbivores consume plants and release carbon dioxide into the atmosphere through cellular respiration.

• Herbivores consume plants and release oxygen into the atmosphere through cellular respiration.

• Herbivores absorb carbon dioxide from the atmosphere and convert it into oxygen during photosynthesis.

• Herbivores absorb oxygen from the atmosphere and convert it into carbon dioxide during photosynthesis.
