Answer 1

Three strategies to define 'heart rate' include using contextual analysis, applying scientific knowledge, and conducting research to confirm the phrase refers to the frequency of the heart's beats.

Step-by-step explanation:

To understand the definition of heart rate as used in the sentence 'After I ran my fastest time ever in a race, my heart rate was very high,' you can employ several strategies:

1. Contextual Analysis: Analyze the context of the sentence to infer that heart rate refers to the speed at which the heart beats, which increases with physical exertion such as running a race.
2. Scientific Knowledge: Utilize your knowledge of Biology to recognize that the phrase heart rate pertains to the number of times the heart beats per minute (beats per minute).
3. Research: Look up reliable sources or educational material that define heart rate to confirm that it means the frequency of the heartbeat, which is a measure of cardiac activity and overall cardiovascular health.

By using these strategies, you can better understand that the heart rate is indicative of the body's response to exercise, as running a race would elevate it due to increased demand for oxygen and nutrients by the muscles.
