A girl on a bicycle has a specific amount of kinetic energy at the base of a hill. She then coasts up the hill without pedaling. She
comes to a stop at the top of the hill. Why is her potential energy at the top of the hill less than her kinetic energy at the bottom of
the hill?
les )
The hill did work on the bicycle as she went up the hill.
The rest of the energy is stored in the muscles of her body.
She still has kinetic energy while stopped on top of the hill
Friction and air resistance created heat on her trip up the hill

18. determine whether each stateme blank space given. ach statement is true (t) or false (f). place your answer in the 8. when a cell is put into an isotonic solution, individual wat put into an isotonic solution, individual water molecules cannot move back and forth across the cell membrane. d. when a cell is put into a hypertonic solution, there is a net movement of water molecules across the cell membrane into the cell. c. when a cell is put into a hypotonic solution, there is a net movement of water molecules across the cell membrane out of the cell. d. the movement of any solvent across a semi-permeable membrane is called osmosis. e. carrier proteins have the ability to change shape and physically move molecules across the cell membrane. f. in facilitated diffusion, the concentration of the molecules to be moved across the cell membrane is higher inside the cell.
