Which of the following tools and activities would measure muscular endurance? pedometer during a mile run test stop watch to count the number of pull-ups performed

Using a pedometer during mile run.  

You're doing a mile run, which helps with cardiovascular endurance. That isn't muscular endurance, so cross that off.

Using a ruler to measure sit and reach results.  

If you feel the tension or pain in your legs and back, that's flexibility, so this is not the right one either.

Using a scale to measure body weight.  

I do not think this is even a type of exercise. You're just measuring your BMI and weight when you do this kind of thing.  

I'd say it's "Using stop watch to count number of pull-ups."  

I think it is this one because, everyone's body is different.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
