Fatima is watching her pet cat, Winter, napping in the sun. Fatima is curious about the heart rate of Winter when she is napping, so she develops this scientific question: Does a cat’s heart rate change while it is napping?

She decides to develop a hypothesis to test this scientific question. What could Fatima’s hypothesis be?

Fatima's hypothesis could be: "If a cat is napping, then its heart rate will be lower compared to when it is awake."

Fatima's hypothesis could be: "If Winter, while napping, is in a relaxed state with lowered physical activity and arousal levels, then her heart rate will decrease compared to when she is awake and active."
