The key difference between ionization energy and binding energy is that ionization energy is the minimum amount of energy needed to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule whereas binding energy is the minimum amount of energy required to remove a particle from a system of particles. Ionization […]
Difference Between Autogenous Theory and Endosymbiotic Theory
The key difference between autogenous theory and endosymbiotic theory is that autogenous theory states that nucleus and cytoplasm form through evolutionary changes in a single prokaryotic lineage while endosymbiotic theory states that some organelles, especially mitochondria and chloroplasts in eukaryotic cells, were once prokaryotic microbes living in a symbiotic relationship. Eukaryotic cells are notably different […]
Difference Between Ethylene and Ethylidene
The key difference between ethylene and ethylidene is that ethylene is a neutral chemical compound, whereas ethylidene is a divalent radical compound. Ethylidene radical forms from ethylene molecules via the rearrangement of molecules; the ethylene molecule contains two carbon atoms bonded to each other via a double bond, and there are two hydrogen atoms attached […]
Difference Between Spontaneous Generation and Panspermia
The key difference between spontaneous generation and panspermia is that spontaneous generation theory believed that life can arise from nonliving matter while panspermia theory believed that life on earth was transferred from somewhere else in the universe to earth. The origin of life on earth is a very big mystery to human beings. There are […]
Difference Between Pyramid of Biomass and Pyramid of Energy
The key difference between pyramid of biomass and pyramid of energy is that a pyramid of biomass shows how much biomass is present in the organisms of each trophic level while a pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level. Ecological pyramids are pyramid-shaped diagrams of energy flow, biomass […]
Difference Between Shape and Geometry of a Molecule
The key difference between shape and geometry of a molecule is that shape of a molecule is the structure of the molecule, excluding the lone pair on the central atom, whereas the geometry of a molecule describes the arrangement of lone pair and bond pair electrons around the central atom of the molecule. We usually […]
Difference Between Ester and Thioester
The key difference between ester and thioester is that ester compounds contain carbon, hydrogen and oxygen atoms whereas thioester compounds contain carbon, hydrogen, oxygen and sulfur atoms. Ester and thioester compounds are related to each other as their name implies; thioester differs from ester due to the presence of a sulfur atom, which replaces one […]
Difference Between First Order and Pseudo First Order Reaction
The key difference between first order and pseudo first order reaction is that first order reactions proceed at a rate that depends linearly only on one reactant concentration whereas pseudo first order reactions are second order reactions that are made to behave as first order reactions. The term “pseudo” means “not genuine”. Therefore, a pseudo […]
Difference Between Miasmatic Theory and Contagionism
The key difference between miasmatic theory and contagionism is that miasmatic theory states that diseases such as cholera and chlamydia are caused by a miasma, which is a poisonous vapour or mist filled with particles from decomposed matter while contagionism is a concept that states the infectious diseases are contagious due to person to person contact or […]
Difference Between Extremophiles and Hyperthermophiles
The key difference between extremophiles and hyperthermophiles is that extremophiles are microorganisms that inhabit extreme environments such as hot niches, ice, and salt solutions, while hyperthermophiles are a category of extremophiles that thrive in extremely hot environments such as thermal vents, etc. Extremophiles are fascinating organisms that thrive in extreme environments where other terrestrial life […]
