This is an example of facilitated diffusion.
Facilitated diffusion is the process of impulsive passive transport of molecules, it is the transfer of substances across a biological membrane from an area of higher concentration to lower concentration by means of carrier molecule.
Answer: A puddle will eventually disappear after a rainstorm ends due to evaporation. This is caused by the heat of the sun, which converts the liquid water into steam (a gas) and evaporates.
Answer: Homeostasis
Explanation: One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.
The box stopped moving because the force stopped pushing . The average speed of the box would be 5 meters per second
