Which term best describes scientists' knowledge of how the brain behaves during sleep?

You didn't list the terms out for me, so I can't say which word is best. But to help, when you're sleeping, the brain is most active.

1. entire bag, then the entire bag of calories

2. the percent of fat would be the percent of fat from the serving size, added up to the entire bag of calories

3/4. the saturated fat would be on the bag label, but im pretty sure if you take the serving size and do the math to figure it out you could find out in total the fiber, saturated fat,etc..

5. no probably not
