The key difference between keratinized and nonkeratinized epithelium is that keratinized epithelium is impervious to water while nonkeratinized epithelium is pervious to water. Based on the presence of keratin protein, there are two types of epithelia as keratinized epithelium and nonkeratinized epithelium. Keratinized epithelium forms the epidermis of land vertebrates. Nonkeratinized epithelium lines the buccal […]

Difference Between N2O4 and NO2
The key difference between N2O4 and NO2 is that N2O4 is diamagnetic, whereas NO2 is paramagnetic. N2O4 is dinitrogen tetroxide while NO2 is nitrogen dioxide. Although the chemical formula N2O4 can be obtained by doubling the stoichiometric values of the chemical formula NO2, these two are different chemical compounds with different chemical and physical properties. […]
Difference Between Catecholamines and Noncatecholamines
The key difference between catecholamines and noncatecholamines is that catecholamines are mainly direct-acting adrenergic drugs that have catechol, while noncatecholamine can be direct-acting, indirect-acting, or dual-acting adrenergic drugs that do not have catechol. Adrenergic drugs mimic the effects of adrenergic nerve stimulation. Catecholamines and noncatecholamines are two types of adrenergic drugs. They can be direct-acting […]
Difference Between Carbon Monoxide and Natural Gas
The key difference between carbon monoxide and natural gas is that carbon monoxide is a harmful greenhouse gas, whereas natural gas is an important source of hydrocarbon compounds. Carbon monoxide and natural gas are two types of gases that occur naturally. Among these two gases, carbon monoxide is considered a toxic gas, while natural gas […]
Difference Between Pyrolusite and Psilomelane
The key difference between pyrolusite and psilomelane is that pyrolusite has a tetragonal crystal system, whereas psilomelane has a monoclinic crystal system. Pyrolusite and psilomelane are two different minerals containing manganese atoms. Although both are oxide minerals, we can easily identify the difference between pyrolusite and psilomelane by their appearance. CONTENTS 1. Overview and Key Difference […]
Difference Between Generative Nucleus and Pollen Tube Nucleus
The key difference between generative nucleus and pollen tube nucleus is that generative nucleus is one of the two male nuclei of seed plants that fuses with the female nucleus in the embryo sac while pollen tube nucleus is the nucleus that guides pollen tube to grow along the pistil into the female embryo sac. […]
Difference Between Muscularis Layer of Esophagus and Stomach
The key difference between muscularis layer of esophagus and stomach is that muscularis layer of the esophagus has two layers while muscularis layer of the stomach has three layers. Gastrointestinal tract or GI tract has four layers. They are mucosa, submucosa, muscularis and serosa. Each layer is composed of different tissues. They also fulfill different […]
Difference Between FeO and Fe2O3
The key difference between FeO and Fe2O3 is that FeO has iron in +2 oxidations state, whereas Fe2O3 has iron in +3 oxidation state. In brief, FeO and Fe2O3 are oxides of iron but having the iron atoms in different oxidation states. FeO is the chemical formula of iron(II) oxide while Fe2O3 is the chemical formula […]
Difference Between Noble Gas Configuration and Electron Configuration
The key difference between noble gas configuration and electron configuration is that a noble gas configuration has only electron pairs whereas an electron configuration can have both paired and unpaired electrons. The term electron configuration refers to the electron sequence or the order of the electrons present in an atom of a particular chemical element. […]
Difference Between Vinylic Halides and Aryl Halides
The key difference between vinylic halides and aryl halides is that vinylic halides are named according to the carbon atom to which the halide atom is bonded whereas aryl halides are named depending on the presence of a cyclic structure to which the halide atom is attached. Vinylic halides and aryl halides are organic chemical […]
