Gastritis is often caused by the gastric mucosa failing to produce the right amounts of gastric juices, the MUSC Digestive Disease Center reports. Sometimes an endoscopic exam reveals the stomach's mucosal layer to be inflamed and swollen. The exam may even show bleeding areas in the stomach.
Daltonâs atomic theory stated that: All the matter is made of atoms which are tiny particles and indivisible. All the given atom of the element is identical in mass, size, shape, and in other properties. All different elements have different types of atoms and also different in their mass, size, shape, and in other properties.
John Dalton. *All substances are made of atoms. Atoms are small particles that cannot be created, divided, or destroyed. *Atoms of the same element are exactly alike, and atoms of different elements are different. *Atoms join with other atoms to make new substances. *Performed experiments and found that elements combine in specific proportions because they are made of individual atoms. *British school teacher and scientist in late 1700's.
