Question
- A. Identify variables that should be controlled when investigating light intensity and photosynthesis rate. is linked...
- B. An unrelated statement about Photosynthesis
- C. A conclusion that ignores the evidence in the question
- D. A broader claim that goes beyond this specification point
Answer
Identify variables that should be controlled when investigating light intensity and photosynthesis rate. is linked... is correct for this objective.
Explanation
Identify variables that should be controlled when investigating light intensity and photosynthesis rate. is linked... is the supported choice because it connects directly to "Identify variables that should be controlled when investigating light intensity and photosynthesis rate" and keeps the explanation inside the AQA GCSE Biology Photosynthesis curriculum. The other options are weaker because they are either unrelated, unsupported by the objective, or too broad for this page.
Common mistake
Controlling Variables in Photosynthesis Experiments
Students often forget to identify all the variables that need to be controlled, focusing only on light intensity.
Remember to consider other factors such as temperature, carbon dioxide concentration, and the type of aquatic organism used, ensuring a fair test.
