Active transport is a cellular transport mechanism. It’s the movement of molecules that are assisted by enzymes along the way to a higher concentration.
In an energy absorbing reaction, the energy of the products is greater than the energy of the reactants. In an energy releasing reaction, the energy of the reactants is greater than the energy of the products.
Answer: Option D.
The atoms and molecules of the liquid water are moving, and the atoms and molecules of the
table are not moving.
Explanation:
The atoms and molecules of the liquid water are moving, and the atoms and molecules of the table are not moving and this is because the atoms and molecules of liquid water are closely packed together and they collide to each other often, thereby moving in random motion in all directions.
The molecules of solid cannot move because they are closely packed together and there is a very strong of attraction which make them to only vibrate and not move and this make solid to have definite shape.
