The absolute magnitude is the magnitude the stars would have if viewed from a distance of 10 parsecs or some 32.6 light years. Obviously, Deneb is intrinsically very bright to make this list from its greater distance. Rigel, of nearly the same absolute magnitude, but closer, stands even higher in the list.

The benefits of using insecticides to kill
mosquitoes that might be carrying Plasmodium is the prevention against the malaria. <span>The malaria
is a serious tropical disease, which in severe cases can be fatal. It is
widespread in tropical and subtropical areas around the world. From a
global point of view, it constitutes a huge public health problem, with 300 to
500 million new cases every year. In Europe, thousands of cases are
diagnosed annually, both among visitors from endemic areas (where the disease
exists), and among immigrants from these areas. Some of these cases end
with the death of the patient.</span>
An endergonic reaction, like photosynthesis, refers to a reaction, which needs the energy to be driven. The activation energy for the reaction is usually greater in comparison to the entire energy of the exergonic reaction. The endergonic reactions are non-spontaneous.
In the given case, in order to accomplish the process, the coupling of the endergonic reaction, that is, thermodynamically unstable reaction with an exergonic, that is, the thermodynamically stable reaction is done so that the entire free-energy change of the coupled reactions becomes negative.
