Chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures into its components. It is quite versatile for it can be used to separate mixtures of solids.
Explanation:
- The two elements of chromatography are the stationary phase and the mobile phase. There are many choices of stationary phases, some being alumina, silica, and even paper. The mobile phase, in liquid chromatography, can also vary. It is often either a solvent or a mixture of solvents and is often referred to as the eluant.
- A careful choice of eluting solvent helps to make the separation more successful. The mixture is placed on the stationary phase. The eluant passes over the mixture and continues to pass through the stationary phase carrying along the components of the mixture.
- Chromatography is used in industrial processes to purify chemicals, test for trace amounts of substances, separate chiral compounds and test products for quality control. Chromatography is the physical process by which complex mixtures are separated or analyzed.
- Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase

Answer:
The correct answer is option c.
Explanation:
Entropy is illustrated as a thermodynamic quantity that demonstrates the thermal energy that does not possess the tendency to get transformed into mechanical work.
At the time of perspiration, the entropy of the body diminishes because of the evaporation of the water that discharges energy from the body and permits the cooling effect to take place. On the other hand, the entropy of water upsurges as the molecules of liquid converts into vapor form, which captivates larger space in the environment.
Yes it could change the park if you remove a population from the national park
Answer:
The correct option is C.
Explanation:
The Wildlife Conservation and Restoration Program and Wildlife Grant Program are two governmental programs that work toward ensuring that wildlife resources are conserved and protected from destruction. These program typically give funds to qualified states to take care of their wildlife resources. To be qualifies for the grant, applicants must be able to present feasible Wildlife Action Plan that spell out how the grant will be utilized. Such plans usually serve as blueprints that showcase the works that need to be done and how it will be executed. Any state that is not able to present a convincing Wildlife Action Plan may end up not getting the grants.
