Terminal Hair vs Vellus Hair Terminal hair and vellus hair being two types of hair, knowing what is hair is useful for a better understanding of the difference between terminal hair and vellus hair. The presence of hairs is considered as unique mammalian characteristic feature. Hairs (hair fibers) are dead structures formed of keratin proteins […]
Difference Between Keratinocytes and Melanocytes
Keratinocytes vs Melanocytes To understand the difference between keratinocytes and melanocytes, one must first understand the anatomy of skin. Skin is the largest organ of the body and acts a mechanical barrier between the underlying tissues and the external environment. Skin is mainly composed of two layers; outer- protective epidermis and inner-connective dermis. Epidermis […]
Difference Between Lophotrochozoa and Ecdysozoa
Lophotrochozoa vs Ecdysozoa Difference between lophotrochozoa and ecdysozoa, the two major bilaterian, is discussed in this article. Based on the recent studies using nuclear and mitochondrial DNA sequences, scientists revised the taxonomy of Animal Kingdom. According to the new molecular phylogenies, scientists identify deutersomes as a separate natural group. Moreover, the major group of […]
Difference Between Fertilization and Implantation
Fertilization vs Implantation The key difference between fertilization and implantation is that they two are different stages in the fetal development process. In this article, the two processes, fertilization and implantation, and the difference between them will be discussed in detail. Both fertilization and implantation are crucial stages of fetal development or pregnancy. Fatal development […]
Difference Between Urea and Urine
Urea vs Urine There are differences between urea and urine though both are considered as the nitrogenous waste products that are excreted through the urinary system in animals. Metabolism of amino acids and nucleic acids results in nitrogenous wastes. When these acids are metabolized, ammonia is formed as the immediate by-product, which is quite toxic to […]
Difference Between Pores and Hair Follicles
Pores vs Hair Follicles Since the words pores and hair follicles are often used interchangeably to define tiny openings in the skin that lately cause acne lesion, let us find out the difference between pores and hair follicles, if there is any. What are Pores? Pores are the tiny openings in the skin and […]
Difference Between Hybridization and Inbreeding
Hybridization vs Inbreeding As breeding and hybridization are important aspects in protecting species, it is useful to know the difference between hybridization and inbreeding. Hybridization and inbreeding are two different types of selective breeding processes. Both processes involve plants and animals with different genetic qualities. The selective breeding methods are usually done artificially to produce […]
Difference Between Coelom and Haemocoel
The key difference between coelom and haemocoel is that the coelom is the principal body cavity of annelids, echinoderms and chordates that originated from the mesothelium while haemocoel is the primary body cavity of arthropods and molluscs which is a reduced form of a coelom. Most multicellular animals possess body cavities filled with fluids that […]
Difference Between Mass Extinction and Background Extinction
Mass Extinction vs Background Extinction Knowing the difference between mass extinction and background extinction becomes important because they are both categories that come under the umbrella term extinction. Extinction is defined as the irreversible disappearance of an entire species of animal or plant from the Earth. It is important to consider the elimination of […]
Difference Between Mendel’s First and Second Law
The key difference between Mendel’s First and Second Law is that Mendel’s first law describes the segregation of the alleles of a given locus into separate gametes during gametogenesis while Mendel’s second law describes the independent transmission of alleles of genes into daughter cells without the influence of each other. Mendelian inheritance describes Mendel’s first […]
