The key difference between extinction and extirpation is that extinction refers to the complete disappearance of a species from the earth while extirpation refers to the disappearance of a species from a given or specific area. Extinction and extirpation are two different phenomena often confused people. Extinction is the termination of an evolutionary lineage. There […]
Difference Between Cilia Stereocilia and Microvilli
The key difference between cilia stereocilia and microvilli is that cilia are tiny hair-like structures composed of microtubules while stereocilia are bundles of hair-like projections composed of actin filaments and microvilli are folds of cell membranes composed of actin filaments. Cilia, stereocilia and microvilli may appear as similar structures when observed from the outside. But […]
Difference Between Aerosol and Particulate Matter
The key difference between aerosol and particulate matter is that the term aerosol refers to a collection of suspended particles and the surrounding gases whereas the term particulate matter refers to the suspended solid or liquid matter in the air. Both terms aerosol and particulate matter describe particles in the air. An aerosol is a […]
Difference Between Acid Value and Saponification Value
The key difference between acid value and saponification value is that acid value gives the mass of potassium hydroxide that is required to neutralize one gram of a chemical substance whereas saponification value gives the mass of potassium hydroxide required to saponify one gram of fat. Although acid value and saponification value are different from […]
Difference Between Flagship and Umbrella Species
The key difference between flagship and umbrella species is that flagship species is a species that acts as a symbol or icon for a defined habitat while umbrella species is the species indirectly involved in the conservation of many other species at the ecosystem or landscape level. In an ecosystem, there are different types of […]
Difference Between Pyrrolidine and Piperidine
The key difference between pyrrolidine and piperidine is that pyrrolidine contains a five-membered ring, whereas piperidine contains a six-membered ring. Pyrrolidine and piperidine are organic compounds that have cyclic structures. Both these compounds are non-aromatic, heterocyclic structures – meaning, these compounds have no delocalized electron clouds (because there are no double bonds) and they have […]
Difference Between Corpus Luteum and Corpus Albicans
The key difference between corpus luteum and corpus albicans is that corpus luteum is the hormone-secreting body formed immediately after ovulation from the opened follicle while corpus albicans is the white degenerated fibrous body. Post ovulation is the period after ovulation (release of ovum). It is also called the luteal phase. During this period, the […]
Difference Between Sodium Propionate and Calcium Propionate
The key difference between sodium propionate and calcium propionate is that sodium propionate contains a sodium cation bound to the propionate anion, whereas calcium propionate contains a calcium cation bound to two propionate anions. Sodium propionate and calcium propionate are ionic compounds containing a cation and an anion. These compounds are two different salts of […]
Difference Between Conditioned Stimulus and Unconditioned Stimulus
The key difference between conditioned stimulus and unconditioned stimulus is that conditioned stimulus produces a learned response to the previously neutral stimulus while unconditioned stimulus produces a response without any previous learning. A stimulus is any internal or external thing that induces our nervous system to respond to it. They cause a reaction in an […]
Difference Between Aluminium Chlorohydrate and Aluminium Zirconium
The key difference between aluminium chlorohydrate and aluminium zirconium is that aluminium chlorohydrate is comparatively less effective as an antiperspirant, whereas aluminium zirconium is more effective as an antiperspirant. Both aluminium chlorohydrate and aluminium zirconium are important as antiperspirants. An antiperspirant or a deodorant is a substance that we can apply on the body to […]
