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

Bond [772]

Answer:Dehydration

Explanation:

Dark urine is usually indicative of dehydration; but there could be more reasons responsible for it. Ideally, when you eat or drink something, it goes through your digestive tract, circulatory system and then to your kidney. Kidneys are where everything is filtered and urine is produced. Urine contains the harmful toxins which need to be eliminated from the body. Darker urine is more concentrated. It is indicative of the fact that unnecessary toxins and wastes are circulating in your body which could mess with your health. This, again, depends on how much fluids you drink throughout the day. But there could be many other reasons responsible for the same.
