The endurance of an athlete is dependent on his or her body's ability to uptake oxygen efficiently, a task carried out by the red blood cells.
Whats the question exactly i dont get it
The average weight of a 7th grader is supposed to be 95-105.
Perhaps, it really, really and really depends on your sex, age and the food you eat.
For boys that are aged 12 to 13 in 7th grade, their weight should be an average of 96 - 110
For girls that are aged 12 to 13 in 7th grade, their average should be 95 to 108...since many girls don't like eating too much food and hate getting fat! :D
Btw, if you might ask me, I am 14 in 10th and weigh 75 pounds, I am really skinny, I hate food, and do some push-ups and other excersices in the morning (this is one way you can loose weight)
So what about you?
