What happens with aerobic respiration? Definition: Aerobic respiration is the internal respiratory processes of organisms using oxygen. The function is to obtain adenosine triphosphate, the universal energy source. From the chemical point of view, oxidation takes place during the reaction: elemental oxygen (O 2) is reduced to water (H 2 O).
Definition: Antigens are foreign proteins against which the immune system forms antibodies. It is not a gene in the traditional sense. The word 'antigen' derives not from 'Genetics', but from the English 'anti body gen erating' (= antibody-producing). What the receptors of the antibodies record as an antigen is the surface structure of the proteins.
Charles Lyell (born November 14, 1797, February 22, 1875) The geologist Charles Lyell is considered the most important co-founder and representative of the principle of actuality. Under the influence of his father, the eponymous botanist Charles Lyell, he initially took a law degree, but nevertheless dealt intensively with botany, geology and the general natural sciences.
Atomic mass, symbol and atomic number Arsenic is a naturally occurring element with the elemental symbol As and the atomic number 33. In the periodic table it stands with an atomic mass of 74.921 u in the 5th main group. The chemical element discovered by Albertus Magnus 1250 is not radioactive and is in a solid state at room temperature.
Definition: The term allergy (from the Greek allos = foreign, ergon = reaction) refers to a reaction of the immune system to contact with allergens. More than 90% of allergens are harmless to the human body. Nevertheless, the immune system usually reacts violently to the antigens. The symptoms are extremely diverse, depending on the allergen and human individually different: itching, rash, shortness of breath, abdominal pain, vomiting, diarrhea, eczema, hives, hay fever and edema are just a selection of possible symptoms.
Atomic mass, symbol and atomic number Aluminum is a naturally occurring element with the elemental symbol Al and the atomic number 13. In the periodic table it stands with an atomic mass of 26.981 u in the 3rd main group. The chemical element discovered by Humphry Davy in 1808 is not radioactive and is in a solid state at room temperature.
Definition: Amphibians (ancient Greek amphibium = double-leaved), also called Lurche, are cold-blooded animals and are considered to be the oldest taxon of terrestrial vertebrates. About 400 million years ago the first amphibians appeared in the geological era of Devon. Almost all amphibians undergo a so-called metamorphosis during their lifetime, which means that their shape changes.
Atomic mass, symbol and atomic number Antimony is a naturally occurring element with the element symbol Sb and atomic number 51. In the periodic table it stands with an atomic mass of 121.750 u in the 5th main group. The chemical element is not radioactive and is in a solid state at room temperature.
What is an atom? Explanation: The word 'atom' goes back to the Greek philosopher Democritus and means 'indivisible'. The idea of the indivisibility of atoms, that is the smallest unit of matter, is thus well over 2,400 years old. However, atoms are not indivisible despite the terminology.
Atomic mass, symbol and atomic number Berkelium is an artificially created element with the element symbol Bk and atomic number 97. In the periodic table it belongs to the actinoids with an atomic mass of 247 u. The chemical element discovered by Glenn T. Seaborg in 1949 is radioactive and is in a solid state of aggregation at room temperature.

Definition: Autoimmune diseases (alt. Autós = self) are diseases in which the immune system recognizes its own body tissue as alien. The triggered immune reaction is directed against the own body. As a result, severe limitations of natural body functions may occur.

What is bioenergy? Definition and explanation: Bioenergy is biomass-derived energy that is available in both solid, liquid and gaseous states. Therefore, this form of renewable energy is universally applicable. The extraction of bioenergy has recently become an important economic factor for many states with little or no gas, coal or oil resources.
