What is morphology?In biology, morphology is the study of the shape and arrangement of parts of living organisms in order to determine their function, development and shape that may have been shaped by evolution. Morphology is particularly important in classifying species because it can indicate how closely related one species is to another. Morphology is also studied in other sciences, such as astronomy and geology. And in language, morphology studies where words come from and why they look the way they do. The concept of form as opposed to function in biology goes back to Aristotle However, the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach (1800).

Drug Antagonism is when two drugs cancel out each other's effects on the body, for example, nicotine canceling out the beneficial effects of blood pressure medicine.
Drug Antagonism is an interaction between two or more medications that have diametrically opposed physiological effects. Drug antagonists may prevent or lessen one or more medications' ability to work. Chemical antagonism is the process by which a drug interacts chemically with either a chemical or another drug, resulting in a diminished or nonexistent effect.
When two medications operating on various receptors and pathways have opposing effects on the same physiologic system, this is referred to as physiologic antagonism. Drugs that form drug-receptor complexes with their targets but do not activate or activate a response are known as antagonists.
