Answer:
True
Explanation:
Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.

This depends on the person, as people have different needs and athletes need more calories then normal scholars. The average is about 1,600-2,100. But again it depends on the person, for example I can only eat about 1,500 calories a day, despite the fact I'm an athlete, my friend however can eat about 2,500. If this is for personal use I would recommend consulting a doctor or trusted adult before you go on a diet. 
Hope this helps :)
