Answer: The reading on the scale will decrease as the elevator descend.
According to Newton's second law of motion which explains that the rate of change of the momentum of a body is directly proportional to, and in the same direction as, the net force acting on it.
In essence as a body moves towards ground, it weighs less and even weighs more upon impact with the ground.
If peradventure, the whole system is in free fall, you, the elevator and the scale will weigh nothing at all.

The best answer to fill in the blank in the question: Active transport is the protein-mediated movement of substances _____, would be: Against a concentration gradient.
Explanation:
In cellular activity there are several means by which a cell may either introduce, or expell, molecules, ions, gases, waste, or water to survive. While some of these elements may enter a cell´s intracellular environment, and leave it, relatively easily, some require the help of proteins present in a cell membrane in order to either enter or exit the cell. Ions, especially, given that they are vital to maintain the cell´s capability of reacting to different stimulus, have to be particularly balanced out and controlled. In order to do so, the cells membrane possesses a series of proteins inserted between the layers that work as both gated channels and also as transporters that will allow the ions to move as they are required by the cell. Active transport then is the active passage by these proteins on the cell´s membrane of ions against their concentration gradients.
