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 happens in anaerobic respiration? Definition: Anaerobic respiration is the inner respiratory process of organisms that are able to do their energy metabolism completely without oxygen. On the chemical level, a redox reaction takes place. Instead of oxygen (O 2), however, nitrates, sulfates or fumarates (and a few others) serve as electron acceptors.
Adaptive Radiation Adaptive Radiation is the evolution of many new species from a single strain. Adapative radiations occur when the species is introduced into different ecological niches. Factors such as geographical isolation and the absence of natural enemies favor the process of Adaptive Radiation.
Overview From the Atom to the Chemical Reaction ... General Chemistry forms the basis for all other branches of chemistry. Without knowing the basics of chemical reactions, chemical bonds and properties of the elements, there is a scientific examination of the other subareas, in particular the Inorganic and Organic Chemistry, not possible.

What is the Beaufort scale? The Beaufort scale is a thirteen-level scale for measuring wind force. Although the use of wind forces is common in the weather forecast, the Beaufort scale is almost never mentioned. Although named after the British admiral and hydrograph Francis Beaufort (see picture), Beaufort has not developed the scale itself.

What is the blastocyst? Definition: The blastocyst (Greek blastos = bud) emerges on the 5th day after fertilization from the morula. At this point, the blastocyst is already in the womb. For the first time in embryogenesis, differentiation of cell types occurs. From the internal cells (embryoblast) the embryo will develop later.

What is a chemical element? Definition: A chemical element is a so-called pure substance, which consists only of itself and can not be split into different individual components using chemical methods. Currently, 118 different elements are known. Chemical elements can be clearly distinguished from each other by their atomic number.
Breathing simply explained: respiration (lat. Respirare = respiration) or respiration is a bi-ambiguous term used in biology, which is why it requires a more precise demarcation. External breathing describes the absorption of oxygen from the air. These include, for example, pulmonary respiration (mammals), gill respiration (fish) or tracheal breathing (insects).
