Question
- A. Describe how heart rate increases during exercise to supply muscles with more oxygenated blood. is linked to...
- B. An unrelated statement about Respiration
- C. A conclusion that ignores the evidence in the question
- D. A broader claim that goes beyond this specification point
Answer
Describe how heart rate increases during exercise to supply muscles with more oxygenated blood. is linked to... is correct for this objective.
Explanation
Describe how heart rate increases during exercise to supply muscles with more oxygenated blood. is linked to... is the supported choice because it connects directly to "Describe how heart rate increases during exercise to supply muscles with more oxygenated blood" and keeps the explanation inside the AQA GCSE Biology Respiration curriculum. The other options are weaker because they are either unrelated, unsupported by the objective, or too broad for this page.
Common mistake
Misunderstanding Heart Rate Response
Students often state that heart rate increases during exercise solely to pump more blood, without mentioning the need for more oxygenated blood specifically for muscle use.
Emphasize that the increase in heart rate during exercise is primarily to supply muscles with more oxygenated blood, which is crucial for meeting the heightened energy demands.
