What does species transformation mean? Art transformation, also known as anagenesis (Greek: ana = upwards; genesis = genesis), is the phenotypic and genotypic alteration of a species without the formation of a new species. The existing species continues to develop. Species conversion is particularly likely in those environments that provide relatively stable conditions for a long time but at the same time have light, transforming selection pressure in a particular direction.
Function, Effects and Synthesis Adrenaline, also known as epinephrine, is used by the adrenal cortex as a stress hormone, especially in mental as well as physical stress situations. The evolutionary purpose of the hormone lies in the physical adaptation to an extraordinary situation, which requires either flight or fight (Fight or Flight).
Definition: The archaic describes an early part of the Earth's early season, the so-called Precambrian. It began about four billion years ago and is divided by scientists into four phases, namely those of the Eoarchic, the Paleo-Archaic, the Meso-Archeic and the Neo-Archeic.
Definition: Allergens are foreign proteins that trigger an immune reaction. This includes allergens to the antigens. The immune system recognizes the antigens and subsequently forms antibodies to fight the supposed, harmful foreign substances. In most cases, allergens are safe for the body.

Australopithecus - ancestor of man? The Australopithecines are an extinct genus of hominids. The name derives from the location (South Africa) of the first fossil of this genus (Latin australis for "south" and Greek pithekos = "monkey"). The fossil, known as the Taung Kid, was discovered in 1924 in a quarry near the South African city of Taung.

What is meant by the atomic radius? Definition and Explanation ... As atomic radius, the distance between atomic nucleus and electron cloud can be defined quite generally. All values for the atomic radius can therefore at best be approximate values, because the distance between the nucleus and the outermost electron in the electron shell is practically barely measurable.
Selection factors Selection factors are those environmental conditions / factors that affect the individuals and thus their fitness. A distinction is made between abiotic (inanimate) and biotic (living) selection factors. The selection factors are crucial for the direction of evolution.
What is biodiesel? Definition, history and production: Biodiesel describes a fuel made entirely from oil plants. In Europe, it is obtained in particular from sunflower or rapeseed (see picture) with the addition of alcohols. Biodiesel produced from vegetable oil is also known as FAME, the short form for Fatty Acid Methyl Esther.

What are CO2 emissions? Definition and explanation: CO 2 emissions refer to greenhouse gases produced by the combustion of various carbonaceous materials such as coal, diesel and gasoline, natural gas, wood or LPG. As a result of these processes, high levels of CO 2 (carbon dioxide) are emitted, which accumulate in the earth's atmosphere in ever-increasing concentrations.
