After a meal, Brian went for a run. While running, his muscles needed more energy. How did diffusion play a role in supplying both nutrients and oxygen to his muscle cells?

After eating lunch, Brian went for a long run. His body needed more energy, and his breathing and heart rate increased. How did diffusion help his muscle cells receive what they needed during the exercise?  (1 mark)

Mary was treated for a cut. Her body needed new cells to repair the wound. What role did diffusion play in this healing process?

Mary was treated for a deep cut on her leg. During healing, her body needed energy and raw materials to make new cells. Explain how diffusion supported this healing process.  ( 1mark)

Faith inhaled deeply after climbing stairs. Based on the diagram, how does diffusion help remove waste gas from her body?

Faith inhaled deeply after climbing stairs. Her breathing became faster as her body worked to remove waste gases and take in oxygen. Based on the diagram, how does diffusion help remove waste gas from her body during this process?  (1 mark)

What process is shown in the image that helps the plant absorb essential nutrients?

During a science experiment, students watered one plant with a solution of dissolved mineral salts and left another plant in dry soil. After several days, the watered plant developed greener, healthier leaves, while the dry plant showed no improvement. What process is shown in the image below that explains why the watered plant absorbed nutrients and grew better?  (1 mark)

A farmer applied compost manure to his spinach garden. A week later, the leaves appeared healthier and darker green. Which process allowed nutrients from the manure to enter the root hairs to support this growth?

A farmer applied compost manure to two sections of his spinach garden. One section had dry soil, and the other was well-watered. After a week, only the watered section showed greener leaves. Which process most likely allowed nutrient uptake in the successful section, and why did the other section show no change?  (1 mark)
