Imagine you somehow developed a chronic disease?

the answer is:

i had an assignment in the biology course where i should write a few paragraphs about an experience. the teacher didn't give us a rubric. if i had one i could have paid closer attention to the criteria that has the highest scores. this could have improved my grade.

hope it !

transportation i would say maybe sorry it its not correct

when you rub, you also apply pressure, that pressure can urge the poop to come out. i think that when your rubbing, you also might be slightly breaking it up and that can further fill the stomach.
