Answer: Alfred Wegener ; Continents
Explanation:
The continental drift theory states that continents of earth have moved over geologic time period relative to each other which appears to have drifted along the ocean bed.
This concept was fully developed and explained by Alfred Wegener in the year 1912 but due to the lack of information about any motive mechanism his theory was rejected.
It is being subsumed by the theory of the tectonic plates by the continents moving because of the movement of the tectonic plates.
A chemical equation is said to be balanced when the number of atoms of each element on the reactant side is equal to the number of atoms of those elements on the product side.
The process of photosynthesis involves carbon dioxide and water, which reacted together to form glucose and oxygen. The balanced equation for photosynthesis is given below:
6H2O + 6CO2 = C6H12O6 + 6O2.
Looking at this chemical equation, you will discover that: there are 12 atom of hydrogen, 18 atoms of oxygen and 6 atoms of carbon on both sides of the equation.
Answer:
Regurgitation of acidic stomach contents into the esophagus, commonly called "heartburn"
Explanation: Esophagus is the part of the alimentary canal,which is a tube that transports food and water substance from the mouth to the stomach. Esophagus has an upper Esophagus sphincter and and the lower Esophagus sphincter. The lower Esophagus sphincter contains muscles that connects the Esophagus and the stomach. When the lower Esophagus sphincter is closed it prevents the movement of Acids and contents in the stomach from traveling backwards from the stomach. When it fails to effectively constrict it causes what is called "HEARTBURN".
