The disease is called Scleroderma
Answer:
d. 60
Explanation:
Both the American College of Sports Medicine and the U.S. Department of Health and Human Services recommend at least 60 minutes of exercise daily for youth under the age of 18. This has been determined to be a good daily dose of exercise in order to allow healthy growth and development of youth below the age of 18th. Which is also why Physical Education classes in the United States are mandatory and last 60 minutes.
When we say energy, we are referring to calories or your calorie count. So when we say energy balance, we mean that your calorie count has to be balanced. Now we all know that when you eat too much, then you will gain much more calories. So if you want to maintain a healthy weight, then your calorie count should be just right. Also, exercise is also very important because if you intake more calories, then you have to make sure to burn it off through exercise so that you can maintain your balanced calorie count.
That situation is a tricky situation...i wish i knew myself.
