- Homologation is the process of certifying that a particular car is roadworthy and matches certain specified criteria laid out by the government for all vehicles made or imported into that country.omologation in India is expensive and time consuming because the authorised body often has to begin by buying the equipment required to test technology-rich cars. Also, the rush for certification means that the authorities sometimes don't have the capacity to handle the volumes.

Whatâs the difference between autologous, homologous (allogenic), and heterologous blood transfusions? Autologous blood transfusion is the collection and re-infusion of the patient’s own blood or blood components. Homologous, or more correctly allogenic, blood transfusions involves someone collecting and infusing the blood of a compatible donor into him/herself.

- Homologous characters (or just homologues) are characters derived through evolutionary descent.For example, hair is a homologous character among mammals because it has a common evolutionaryorigin (ascertained by examination of development, anatomy, genetics, etc).or example, mammals all share some characters incommon (e.g., hair and mammary glands). However, only homologous characters (defined below)should be used for classifications and to infer evolutionary relationships. Character states are the various conditions of a homologous character.

What is Homologous Recombination? Image Credit: Main Image: Homologous recombination is a type of genetic recombination in which nucleotide (molecules which are joined make the structural units of RNA and DNA) sequences are exchanged between two similar or identical molecules of DNA.

Milankovitch Cycles: How the Earth and Sun Interact While we're all familiar with the axis of the earth pointing toward the North Star (Polaris) at an angle of 23.45° and that the earth is approximately 91-94 million miles from the sun, these facts are not absolute or constant.

What is DNA Methylation? 10 most extreme places on Earth. DNA methylation is the biological process by which a methyl group, which is an organic functional group with the formula CH 3, is added to DNA nucleotide. DNA, or deoxyribonucleic acid, is an important nucleic acid that stores the genetic information for any given organism.

Homology (biology) The principle of homology: The biological relationships (shown by colors) of the bones in the forelimbs of vertebrates were used by Charles Darwin as an argument in favor of evolution. In the context of biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different taxa. A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.

- The word homology, coined in about 1656, derives from the Greek ὁμόλογος homologos from ὁμός homos same and λόγος logos relation. In biology, two things are homologous if they bear the same relationship to one another, such as a certain bone in various forms of the hand. common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.

Homogamy (sociology) Homogamy (sociology) Homogamy is marriage between individuals who are, in some culturally important way, similar to each other. Homogamy may be based on socioeconomic status, class, gender, ethnicity, or religion, or age in the case of the so-called age homogamy. It is a form of assortative mating.

Homologous recombination Homologous recombination is a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. It is most widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks.omologous recombination is also used in horizontal gene transfer to exchange genetic material between different strains and species of bacteria and viruses.

Pasteurized vs. Homogenized Milk: Whatâs The Difference? Homogenization is an entirely separate process that occurs after pasteurization in most cases. The purpose of homogenization is to break down fat molecules in milk so that they resist separation. Without homogenization, fat molecules in milk will rise to the top and form a layer of cream.

Definitions &Translations Homologation is the granting of approval by an official authority. This may be a court of law, a government department, or an academic or professional body, any of which would normally work from a set of strict rules or standards to determine whether such approval should be given. The word may be considered very roughly synonymous with accreditation, and in fact in French and Spanish may be used with regard to academic degrees. Certification is another possible synonym, while to homologate is th

Human evolution Homo sapiens. Human evolution, also known as hominization, is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus Homo – and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.

Evidence of Evolution Homology is the relationship between biological structures or sequences that are derived from a common ancestor. Homologous traits of organisms are therefore explained by descent from a common ancestor.
