Question 2
What is Austyn's heartrate before exercising? (1 point)
Answer: 90
Question 3
What is Shanice's heart rate before exercise? (1 point)
Answer: 80
Question 4
Identify Austyn's highest heart rate. (1 point)
Answer: 210
Question 5
Identify Shanice's highest heart rate. (1 point)
Answer: 200
Question 6
Which minute shows both girls' peak heart rate? (1 point)
Answer: Minute 7
Question 7
Describe in 1-2 sentences, what happens to the heart rates between the second and third minutes. (2 points)
Answer: The heart rates of both girls increase between the second and third minutes.
Question 8
Are the girls exercising more or resting during minutes nine and ten? Justify your answer in 1-2 sentences. (2 points)
Answer: The girls are resting during minutes nine and ten as their heart rates decrease back towards their resting levels.
Question 9
Explain how the graph demonstrates homeostasis with at least 3 sentences. Be sure to include specific data from the graph. (4 points)
Answer: The graph shows the heart rates of the two girls returning to their resting levels after exercise, demonstrating homeostasis. Both Austyn and Shanice's heart rates peak during exercise but then gradually decrease back down towards their initial levels. This ability of the body to regulate and maintain stable internal conditions is an example of homeostasis.
Question 10
Why is it important for heart rate to be monitored during exercise? (2 points)
Answer: Monitoring heart rate during exercise is important to ensure that individuals are working out at an appropriate intensity level to achieve their fitness goals without overexertion. It can also help identify any potential cardiovascular issues or abnormalities that may arise during physical activity.
