Explanation:

Question 5

Step1: Recall the formula for maximum heart rate (MHR)

The formula to estimate maximum heart rate is \( MHR = 220 - age \).

Step2: Substitute Jeremy's age into the formula

Jeremy is 16 years old, so \( MHR = 220 - 16 = 204 \) bpm. Wait, but let's check again. Wait, the formula is 220 - age. So 220 - 16 = 204? Wait, no, wait, maybe I made a mistake. Wait, 220 - 16 is 204? Wait, 220 - 10 is 210, 220 - 16 is 204? Wait, but let's check the options. Option D is 204 bpm. Wait, but let's confirm the formula. The standard formula for maximum heart rate is \( MHR = 220 - age \). So for a 16 - year - old, \( 220-16 = 204 \) bpm.

Endorphins are known as "happy hormones" that are released during exercise and are associated with feelings of happiness and reduced pain. Cortisol is a stress hormone, adrenaline is related to the fight - or - flight response, and progesterone is a sex hormone. So the hormone released that makes Mariam feel happier is endorphins.

Body composition is defined as the proportion of fat, bone, water, and muscle in the body that contributes to overall weight. BMI (Body Mass Index) is a ratio of weight to height squared, cellulite is a type of fat deposition, and overall health is a broad term for the state of well - being. So the term that fits the description is body composition.

Answer:

D. 204 bpm
