The way in which organisms are expressed differently between different species is because they are diverse.

1.Constructing Expression: Constructing expression is the implantation of a foreign gene into an organism to produce a specific protein to demonstrate the function of the gene.
2.Cell expression: Cell expression refers to the process of genetic transcription, translation, and protein modification within the silver number of cells, as well as how gene information is expressed in cells.
3.Animal model expression: Animal model expression refers to the implantation of genes into animals to express specific proteins to study gene function.
4.Mouse expression: Mouse expression refers to the implantation of genes into mice to express specific proteins to study gene function.
5.Plant expression: Plant expression refers to the implantation of genes into plants to express specific proteins in order to study gene function.
6.Bacterial expression: Bacterial expression refers to the implantation of genes into bacteria to express specific proteins in order to study gene function.
7.Prokaryotic expression: Prokaryotic expression refers to the implantation of genes into prokaryotes to express specific proteins to study the function of basal mosaicot.
8.Antibody expression: Antibody expression refers to the implantation of a gene into an animal or bacterium to express a specific antibody to study gene function.

There are two types of types: intraspecific relationships and interspecific relationships.
Intraspecific relationships include intraspecific mutual assistance and intraspecific competition. It refers to an interspecific relationship in which two species live together and struggle for limited nutrition, space, and other common needs. The result of competition may have a restraining effect on both competitors, most of the time in favor of one party, the other party is eliminated, and one party replaces the other.
Interspecific relationships include parasitism, predation, competition, and mutualistic symbiosis. There are two concepts of symbiosis, broad and narrow. In a narrow sense, it refers to two kinds of living together to create favorable living conditions for each other, which is more advantageous and more life-effective than living alone; Interdependence, mutual interdependence, once separated, neither side can live normally.
According to the cohabitation status, it is divided into external symbiosis and internal symbiosis. Symbiosis is one.

There are seven relationships: interspecific coexistence, mutualism, symbiosis, antagonism, competition, parasitism, and predation.
Interspecific coexistence: two microorganisms live together without affecting each other and do not show obvious beneficial or harmful relationships. Such as Lactobacillus and Streptococcus.
Mutuality: A loose association between microorganisms, in which one or both parties are beneficial. Such as ammoniating bacteria and nitrifying bacteria.
Symbiosis: Two microorganisms are closely combined to form a special symbiont, which produces a new structure in tissue and morphology, and has a certain division of labor in physiology. Symbiosis is divided into reciprocal symbiosis and partial symbiosis. For example, lichens formed by the symbiosis of algae and fungi.
Antagonism: When two microorganisms live together, one microorganism produces a special metabolite or changes environmental conditions, thereby inhibiting or even killing the other microorganism.
Competition: Microorganisms living together compete for limited nutrients or space to grow, resulting in inhibition of the growth of both microorganisms. Competition is ubiquitous in nature and is the driving force behind the development and evolution of microorganisms.
Parasitism: An organism lives on the surface or body of another organism and obtains nutrients from the cells, tissues or fluids of the latter, the former is called a parasite, the latter is called a host, and the parasite is generally harmful to the host. Such as bacteriophages and bacteria.
Predation: One microorganism directly ingests another microorganism. For example, the predation of protozoa on bacteria, the predation relationship is of great significance in controlling population density and forming the ecological food chain.
There are five basic ways of expression, one is narrative, the second is descriptive, the third is lyrical, the fourth is argumentative, and the fifth is illustrative. >>>More

It's really embarrassing to be invited because I opened a small teahouse, and it's really a big question about the taste of tea, just like a thousand people reading Shakespeare and having a thousand Hamlets, there are personal feelings, and the mood is not the same, the feeling of drinking tea may be different, today it is bitter, tomorrow it is sour, and the day after tomorrow it is sweet; There are also scientific standards, different processes, different tree species, and different tea ages, all of which determine the final result of the tea - the color and taste of the soup are different. Therefore, I personally think that to clearly understand the taste of tea is to drink more and learn more, if you drink more, you will naturally feel the difference, black tea is definitely different from black tea; Learn more, you can find a special term to describe it, and the two answers with the highest votes above are different aspects that are professionally described. <>
