Passive transport does not require ATP energy to be spent by the cell; active transport involves the cell spending energy to move materials.
Explanation:
Molecules naturally move from areas where they are abundant (high concentration) to where they are less common (low concentration) in a process called diffusion. Some molecules will cross in or out of a cell membrane in this way without the cell having to spend any energy to do so. This is passive transport.
When the cell wants to build up an excess of molecules on one side of the cell membrane (inside or outside) it must spend energy to counteract the tendency towards diffusion (described above). The cell must spend energy to do this and this is referred to as active transport.

Answer:
Hardness of a mineral is defined as the resistance to breaking, and density is defined as the mass of a substance per unit volume.
The density and hardness of a mineral, that is formed from through metamorphism are relatively much harder because the metamorphic minerals are formed under extremely high temperature and pressure conditions. These are high-grade minerals.
On the other hand, the density and hardness of a mineral formed through evaporation are much weaker in nature, because these minerals are formed when the water is eliminated due to the high rate of evaporation.
So, it can be concluded that the density and hardness of as mineral formed through the metamorphic process is highly stronger and harder than those that are formed through evaporation.
