Biomolecule
A biomolecule or biological molecule is a loosely used term for molecules and ions that are present in organisms, essential to some typically biological process such as cell division, morphogenesis, or development.

Coal
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.

Exoskeleton
An exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton") is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human.

Geologic time scale
The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time.

Inorganic compound
An inorganic compound is typically a chemical compound that lacks C-H bonds, that is, a compound that is not an organic compound, but the distinction is not defined or even of particular interest.

Life
Life is a characteristic that distinguishes physical entities that do have biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased, or because they never had such functions and are classified as inanimate.

Limestone
Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs.
New!!: Biogenic substance and Limestone · See more »
Mineral
A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes.

Neurotransmitter
Neurotransmitters are endogenous chemicals that enable neurotransmission.

Organic compound
In chemistry, an organic compound is generally any chemical compound that contains carbon.
