guajiro [1.7K]

Answer:

99 to 138.6 bpm

Explanation:

The heart rate of an individual is a measure of how many times the heart beats in a given time, usually measured in beats per minute (bpm).

Resting heart rate is the number of beats per minute when an individual at rest. Generally, it can be understood that the lower the resting heart rate, the more physically fit an individual is.

The maximum heart rate for an individual is 220 minus their age. The target heart rate for moderate physical activity is 50-70% of the maximum heart rate and for vigorous physical activity it is 70-85% of the maximum heart rate.

Based on Holly's age, her maximum heart rate is 220 - 22 = 198 bpm

Her heart rate zone for moderate physical activity is 50-70% of 198 bpm: 99 to 138.6 bpm

Her heart rate zone for vigorous physical activity is 70-85% of 198 bpm: 138.6 to 168.3 bpm

Whats are the pros and cons of a endoskeleton?
Softa [21]

Well, an endoskeleton is an internal skeleton, like humans have. Pro: Bones do not get broke as easily, since they are inside of the body. Bones that break also heal more quickly in an endoskeleton, since they have tissue and blood surrounding it and transferring nutrients. Con: The flesh can get easily damaged. There is no shedding with endoskeletons, so a new skeleton cannot be grown in the event of an injury.
