Living Systems and Processes

Imagine Oliver, Emma, and Mia are on a wild adventure in the jungle. They come across a strange animal. Which of the following could this animal do to obtain a substance needed for cellular respiration?

• Feast on the delicious fruits of the jungle

• Drink from a crystal clear stream

• Exhale oxygen while running from a predator

• Bask in the warm sunlight filtering through the trees

Imagine William, Charlotte, and Kai are on a thrilling adventure in a magical forest. They stumble upon a mysterious image carved on a tree, which turns out to be the carbon cycle. Can you help them figure out which letter represents carbon being released through cellular respiration?

• C

• D

• E

• G

Imagine Jackson, Zoe, and Elijah are on a mission to Mars. They are studying the carbon cycle and need to know which processes would add carbon to the Mars atmosphere. Can you help them?

• evaporation and decomposition

• photosynthesis and combustion

• cellular respiration and combustion

• photosynthesis and cellular respiration

Imagine this, Isla, Anika, and James are on a space mission. They brought a plant with them and somehow all the oxygen in their spaceship got depleted for a week. What do you think would happen to the plant in such a situation?

• The plant would start a party and photosynthesis would increase.

• The plant would feel a bit under the weather and photosynthesis would decrease.

• The plant would start working out and cellular respiration would increase.

• The plant would take a nap and cellular respiration would decrease.

Imagine this, Jackson, Henry, and Luna are having a science debate. They are discussing about cellular respiration. Jackson claims that if an organism starts with 6 grams of material, the same amount of material will be produced, based on the Law of Conservation of Mass. Is Jackson correct?

• No, 0 grams will be produced

• Yes, 6 grams will be produced

• No, 12 grams will be produced

• No, 18 grams will be produced

Imagine this: Zoe, Daniel, and Arjun are high-level athletes. After an intense workout, they start their "cool down" routine. They slow down their actions, breathe deeply, and munch on a snack. Can you guess why this routine speeds up their recovery process?

• By breathing deeply, they release more carbon dioxide, which kickstarts the energy production process in their cells.

• Through this cool down routine, they take in oxygen and sugar. This allows their cells to produce energy through cellular respiration.

• By cooling down, they take in carbon dioxide and water. This enables their cells to produce energy through cellular respiration.

• When they snack, they take in energy which converts to sugar. This sugar is needed by the body to produce oxygen for their muscles to begin cellular respiration.

Imagine Henry, Aria, and Grace are tiny explorers journeying inside a cell! Which of the following statements best explains the exciting adventure they would experience during the general process of cellular respiration?

• They would see the cell taking in oxygen and water to create food in the form of sugar.

• They would witness the cell using energy from the sun and water to create food in the form of sugar.

• They would observe the cell breaking down sugar from food to combine with oxygen, creating usable energy.

• They would watch the cell taking in carbon dioxide and releasing oxygen through the cells, thereby providing energy.

James, Henry, and Benjamin were having a debate about photosynthesis. They were trying to figure out how the materials used during photosynthesis provide evidence for the Law of Conservation of Mass. Can you help them out?

• James suggested that the total mass of oxygen used in photosynthesis is equal to the amount carbon dioxide used.

• Henry thought that the total mass of glucose used in photosynthesis is equal to the amount of carbon dioxide produced.

• Benjamin argued that the total amount of water and carbon dioxide produced will equal the total amount of glucose and oxygen initially used.

• Or, could it be that the total amount of glucose and oxygen produced will equal the total amount of water and carbon dioxide initially used?

Imagine Henry, Aria, and Evelyn are playing a game of 'Carbon Cycle Tag'. How would this game support the Law of Conservation of Mass?

• The total amount of carbon decreases, as it moves from Henry to Aria to Evelyn in the game.

• The total amount of carbon does not change as it moves from Henry to Aria to Evelyn in the game.

• The total amount of carbon gradually increases, as it moves from Henry to Aria to Evelyn in the game.

• The total amount of carbon changes depending on whether it's with Henry, Aria, or Evelyn in the game.

Imagine Scarlett, Arjun, and David are on a thrilling adventure to understand the carbon cycle. They come across a mysterious point labeled 'G'. Can you help them figure out what's happening at this point?

• Scarlett suggests that carbon is transformed by plants to make food

• Arjun thinks that carbon is being absorbed by the water from the atmosphere

• David believes that carbon is entering the atmosphere due to the combustion of fossil fuels

• Or is it that carbon is being manufactured by removing fossil fuels from the environment?
