The male reproductive structure of a plant produces a sticky substance called pollen. Pollination occurs when a butterfly moves the pollen from the stigma to the ovule." Which statement will correct the error in the passage?

Pollen moves from the ovule to the pistil.
Pollen moves from the stamen to the stigma.
Pollen moves from the stigma to the ovule.
Pollen moves from the stigma to the stamen.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !
