is the study of microscopic organisms, those being unicellular (single
cell), multicellular (cell colony), or acellular (lacking cells).
Microbiology encompasses numerous sub-disciplines including
parasitology, and bacteriology.
is a biological scientist
who studies microscopic life forms and processes or works in the field of
microbiology. Microbiologists investigate the growth, interactions and
characteristics of microscopic
fungi, and some types of parasites and their vectors. They contribute much
to the field by trying to understand and learn about the interaction
between these microbes
and the environment and also among themselves and other organisms.
is a branch of
biochemistry, and biophysics concerned with the molecular structure of
biological macromolecules, especially proteins and nucleic acids, how they
acquire the structures they have, and how alterations in their
their function. This subject is of great interest to biologists because
macromolecules carry out most of the functions of cells, and only by
coiling into specific three-dimensional shapes that they are able to
perform these functions. This architecture, the "tertiary structure" of
molecules, depends in a complicated way on the molecules' basic
composition, or "primary structures."
aims at the mathematical
representation, treatment and modeling of biological processes, using
techniques and tools of applied mathematics.
involves the development and
application of data-analytical and theoretical methods, mathematical
modeling and computational simulation techniques to the study of
biological, behavioral, and social systems.
uses natural variation and disparity to understand
the patterns of life at all levels—from genes to communities—and the
critical role of organisms in ecosystems. Comparative biology is a
cross-lineage approach to understanding the phylogenetic history of
individuals or higher taxa and the mechanisms and patterns that drives it.
Comparative biology encompasses Evolutionary Biology
, Systematics, Neontology, Paleontology, Ethology, Anthropology, and Biogeography as well
as historical approaches to Developmental biology,
and many other areas of the biological sciences. The comparative
approach also has numerous applications in human health, genetics,
biomedicine, and conservation biology. The biological relationships
(phylogenies, pedigree) are important for comparative analyses and usually
represented by a phylogenetic tree or cladogram to differentiate those
features with single origins (Homology) from those with multiple origins (Homoplasy).
is any substance – such as an element, isotope,
molecule, or phenomenon – that provides scientific evidence of past or
present life. Measurable attributes of life include its complex physical
and chemical structures and also its utilization of free energy and the
production of biomass and wastes. Due to its unique characteristics, a
biosignature can be interpreted as having been produced by living
organisms; however, it is important that they not be considered definitive
because there is no way of knowing in advance which ones are universal to
life and which ones are unique to the peculiar circumstances of life on
Earth. Nonetheless, life forms are known to shed unique chemicals,
including DNA, into the environment as evidence of their presence in a

biology of regeneration, asexual reproduction and metamorphosis and in the
growth and differentiation of stem cells

is the biological process that causes an
organism to develop its shape. It is one of three fundamental aspects of
developmental biology along with the control of cell growth and cellular
differentiation, unified in evolutionary developmental biology (evo-devo).The
process controls the organized spatial distribution of cells during the
embryonic development of an organism. Morphogenesis can take place also in
a mature organism, in cell culture or inside tumor cell masses.
Morphogenesis also describes the development of unicellular life forms
that do not have an embryonic stage in their life cycle, or describes the
evolution of a body structure within a taxonomic group. Morphogenetic
responses may be induced in organisms by
, by environmental
chemicals ranging from substances produced by other organisms to
radionuclides released as pollutants, and other plants, or by mechanical
stresses induced by spatial patterning of the cells. (beginning of the
Biological Life Cycle
is a series of changes in form that an
organism undergoes, returning to the starting state. The concept is
closely related to those of the
, development and ontogeny, but differs from them in
stressing renewal. Transitions of form may involve growth, asexual
reproduction, and/or sexual reproduction.

sub-discipline of biology, its focus is in how organisms, organ systems,
organs, cells, and biomolecules carry out the chemical or physical
functions that exist in a living system.
is a complex network of biologically
relevant entities. As biological organization spans several scales,
examples of biological systems are populations of organisms, or on the
organ- and tissue scale in mammals and other animals, the circulatory
system, the respiratory system, the nervous system, etc. On the micro to
the nanoscopic scale
, examples of
biological systems are cells, organelles, macromolecular complexes and
regulatory pathways. A biological system is not to be confused with a
living system, which is commonly referred to as life. For further
information see e.g. definition of life or synthetic biology.
is a taxonomic rank used in the
classification of organisms and recognized by the nomenclature codes.
Other well-known ranks are life, domain, kingdom, phylum, class, family,
genus, and species, with order fitting in between class and family. An
immediately higher rank, superorder, may be added directly above order,
while suborder would be a lower rank. A taxonomic unit, a taxon, in that
rank. In that case the plural is orders (Latin ordines). Example: The
Juglans (walnut) and Hickory trees belong to the family Juglandaceae (or
walnut family), which is placed in the order Fagales.

is any substance that has been
engineered to interact with biological systems for a medical purpose -
either a therapeutic (treat, augment, repair or replace a tissue function
of the body) or a diagnostic one.
is a material intentionally made from
substances derived from living (or once-living) organisms.
is a material engineered to have a
property that is not found in nature. They are made from assemblies of
multiple elements fashioned from composite materials such as metals or
plastics. The materials are usually arranged in repeating patterns, at
scales that are smaller than the wavelengths of the phenomena they
influence. Metamaterials derive their properties not from the properties
of the base materials, but from their newly designed structures. Their
precise shape, geometry, size, orientation and arrangement gives them
their smart properties capable of manipulating electromagnetic waves: by
blocking, absorbing, enhancing, or bending waves, to achieve benefits that
go beyond what is possible with conventional materials.
is a multi-step, enzyme-catalyzed
process where substrates are converted into more complex products in
living organisms. In biosynthesis, simple compounds are modified,
converted into other compounds, or joined together to form macromolecules.
This process often consists of metabolic pathways. Some of these
biosynthetic pathways are located within a single cellular organelle,
while others involve enzymes that are located within multiple cellular
organelles. Examples of these biosynthetic pathways include the production
of lipid membrane components and nucleotides.

is a similarity of one organism, usually an
animal, to another that has evolved because the resemblance is selectively
favoured by the behaviour of a shared signal receiver that can respond to
both. Mimicry may evolve between different species, or between individuals
of the same species. Often, mimicry evolves to protect a species from
predators, making it an antipredator adaptation. The resemblances that
evolve in mimicry can be in appearance, behaviour, sound or scent. Mimicry
may be to the advantage of both organisms that share a resemblance, in
which case it is a mutualism, or mimicry can be to the detriment of one,
making it parasitic or competitive.
