What is biodiversity? Definition and explanation: The term biodiversity describes as part of biodiversity the totality of all animal and plant species as well as all microorganisms and fungi that inhabit a certain area. Depending on whether some species dominate in the region in question and others are rare or all the species living there are about the same number, species diversity is considered to be smaller or larger.
Information and Definition: "Only act on the maxim that you want at the same time to become a universal law." - Immanuel Kant Altruismus (from the Latin age = the other) refers to selfless behavior, in which by using personal resources a service is provided, without requiring or to expect a return for it.
Discovery, structure and function The neurotransmitter acetylcholine (ACh) is considered the most important neurotransmitter due to its elementary control function of vegetative processes in vertebrates. In 1921, acetylcholine, the first neurotransmitter ever, was discovered by pharmacologist Otto Loewi in experiments with frog hearts.
Species genesis through geographical isolation Allopatric speciation is considered one of the main reasons for the emergence of new species and requires a geographical isolation of at least two subpopulations. Reasons for this kind of geographical separation can be, for example: Continental drift Mountain formation Climate change (eg.

Living thing or no living thing? The vast majority of biologists and scientists believe that viruses are not living things. On the one hand, because a virus does not have its own metabolism. On the other hand, because it can not multiply without a foreign host cell. For viruses 'infiltrate' into other host cells and reprogram them so that only their own virus DNA is read and replicated, instead of the actual DNA of the cell.
