Adam Smith described self-interest and competition in a market economy as the "invisible hand" that guides the economy. This episode of the Economic Lowdown Podcast Series explains these concepts and their importance to our understanding of the economic system.
Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
Answer:
The action of the shifting continental plates of Earth has important effects on the course of speciation of living organisms by reproductively isolating populations or allowing previously separated populations to interbreed..
Explanation:
The formation of geological barriers such as mountains special cause of allopatric type, these barriers cause isolation which prevents two or more groups from mating each other regularly and finally there is speciation. On the other hand the movement of continental masses for example can cause the union of islands that allows a new genetic crossing between populations.
The amplitude. Don't mind that other dude that attempted to answer. lol.
