Answer: EXERGONIC; ENDERGONIC
Explanation:
An Exergonic reaction is one that occurs spontaneously, with the release of high amount of energy usually in form of ATP. a good example of this is the oxidation of glucose (glycolysis) in the Human body. 
Whereas an energetic reaction is one that will ONLY occur in the supply of energy. A good example is biosynthethic reaction such as
- formation of glycogen (glycogenesis) 
- formation of lipids etc
 
        
             
        
        
        
Answer:
C
Explanation:
Because between the earth and sun is empty space (vacuum) transfer of heat from the sun to earth can only occur through radiation-  because convection and conduction require a medium. The is the same process that warms your hands when you place them beside a fire. When you put your hands above the fire, they are warmed through convection.

The answer is (3) an increase in the proportion of offspring <span>that have favorable characteristics.
</span>In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Peppered moth color variation is a good example of natural selection.<span>During the Industrial revolution, due to pollution, trees become darker in the urban area. Light-colored moths were, thus, easy prey. The dark-colored moths were able to camouflage on dark trees and avoid predators. The phenomenon is known as industrial melanism. So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.
Therefore, the </span>proportion of offspring <span>that have favorable characteristics in such environment will increase.</span>
