The key difference between type 1 and type 2 pneumocytes is that type 1 pneumocytes are thin and flattened alveolar cells that are responsible for the gas exchange between alveoli and capillaries, while type 2 pneumocytes are cuboidal alveolar cells that are responsible for the secretion of pulmonary surfactants that reduce surface tension in the […]

Difference Between Compressed Gas and Compressed Air
The key difference between compressed gas and compressed air is that compressed gas contains natural gas, whereas compressed air contains a mixture of gases having a composition similar to atmospheric air. The term “compressed” refers to flattened by pressure. In the case of gases, it describes the process of filling gas into cylinders under a […]
Difference Between Acceleration and Momentum
The key difference between acceleration and momentum is that acceleration refers to the rate of change in velocity of a moving object, whereas the momentum of an object is the product of the mass of the object and its velocity. Acceleration is the rate of change of the velocity of an object along with time. […]
Difference Between Composite Transposons and IS Elements
The key difference between composite transposons and IS elements is that composite transposons are a type of transposons that carry accessory genes such as antibiotic resistance genes, while IS elements (or Insertion Sequence elements) are transposable elements that carry only genes that code transposase that catalyze the transposition activity. A transposon is a fragment of DNA that can change […]
Difference Between Capsule and Glycocalyx
The key difference between capsule and glycocalyx is that capsule is an organized, well defined, condensed extracellular layer that is tightly bound to the cell envelope of bacteria, while glycocalyx is an additional layer composed of polysaccharides and/or polypeptides outside the cell wall of bacteria. Some bacteria have an additional layer called glycocalyx outside the […]
Difference Between Molten and Aqueous
The key difference between molten and aqueous is that the term molten refers to the liquid state of materials that are liquified by heat, whereas the term aqueous refers to the liquid state of materials that are liquified by dissolving in water. The terms molten and aqueous has different meanings, but both are liquid states […]
Difference Between Clay and Ceramic
The key difference between clay and ceramic is that clay contains moistened minerals such as aluminum silicates and crystalline silica, whereas ceramic contains metal oxides such as zirconium oxide, silica oxide or silica carbide. The terms clay and ceramic are usually compared in the field of pottery and as kiln materials. These materials have many important […]
Difference Between Unambiguous and Degenerate Code
The key difference between unambiguous and degenerate code is that genetic code is an unambiguous code since a particular codon always codes for the same amino acid, while genetic code is a degenerate code since one amino acid may be specified by more than one codon. Genes are the structural units of heredity. There is […]
Difference Between Freeze Fracture and Freeze Etching
The key difference between freeze fracture and freeze etching is that freeze fracture is the breaking of a frozen specimen to reveal internal structures, while freeze etching is the vacuum-drying of an unfixed, frozen and freeze-fractured biological sample. Freeze fracture and freeze etching are two procedures that are helpful to study details of three-dimensional structures […]
Difference Between Detrital and Grazing Food Chain
The key difference between detrital and grazing food chain is that detrital food chain is a food chain that begins with dead organic matter as the main source of energy while grazing food chain is a food chain that begins with green plants as the main source of energy. A food chain illustrates the feeding […]
