MS6:

- Diffusion is the movement of molecules from an area of high concentration to low concentration (1)

- In lungs, oxygen diffuses from the air into the blood, and carbon dioxide diffuses from the blood into the air (1)

MS7:

- 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂ (1)

MS8:

- Limiting factors (e.g., light, carbon dioxide, water) restrict the rate of photosynthesis (1)

- If one factor is in short supply, it limits the overall rate, even if other factors are in abundance (1)

- Understanding limiting factors helps optimize plant growth and crop yields (1)

MS9:

- Population growth rate is initially exponential (1)

- As population size increases, resources become limiting and growth rate decreases (1)

- Eventually, the growth rate levels off and the population reaches a carrying capacity (1)

- Carrying capacity is the maximum population size that can be sustained by the available resources (1)

MS10:

- Genetically modified crops can be created with desirable traits, such as resistance to pests or herbicides (1)

- Crops can be modified to produce higher yields or improved nutritional value (1)

- Biotechnology can help address food security challenges (1)
