Animal movements of the handa are said to be autovisible. Chimpanzees are able to imitate, using even parts of their own body which they cannot see, simple movements (nonautovisible versus autovisible or hand movements).
autovoxiphillia (s) (noun), autovoxiphillias (pl)
The fondness or adoration of a person’s own voice: Marie loved to sing and even recorded her songs to listen to, which showed her strong tendency for autovoxiphillia.
A reference to a parasite that passes through the different stages of its life cycle in the same host individual.
autoxidation, auto-oxidation, autooxidation
1. The oxidation by direct combination with oxygen (as in air) at ordinary temperatures: "The rancidity of fats and oils is caused by autoxidation."
2. The combination of a substance with molecular oxygen at ordinary temperatures.
An independent polyp capable of feeding itself.

A polyp is described as a cylindrical organism with a thin body-wall consisting of two single layers of cells, the ectoderm and the endoderm separated by a gelatinous noncellular layer or mesogloea.

At one end there may be a mouth which is usually surrounded by tentacles. Polyps may be single (e.g, Hydra) or colonial (e.g. the coral-forming organisms). The latter are formed by repeatd budding from a parent polyp.

In such colonies a tube or coenosarc links the body-cavities of all the individuals with one another. There may be many different kinds of polyp in a colony, each specialized for some different function; such as, feeding, reproduction, protecting, etc.

1. Pertaining to genes in a homozygote that are copies of the same ancestral gene as a result of a mating between related individuals.
2. Indicating genes in a homozygote that are copies of the identical ancestral gene as a result of a consanguineous (common ancestor) mating.

A homozygote is a nucleus, cell, or organism with identical alleles ( forms of the same gene) of one or more specific genes.

auxoautotrophic (adjective), more auxoautotrophic, most auxoautotrophic
1. A reference to an increase in the nursing, tending, and self-nourishing; of plants: Farmers are specialists in the care auxoautotrophic wheat, corn, and other food products.
2. Relating to an organism capable of increasing the synthesizing of its own food from inorganic substances, using light or chemical energy: Green plants, algae, and certain bacteria are examples of auxoautotrophic vegetation.
1. A bioassay of certain compounds, usually antibiotics or vitamins, by evaluating their ability to enhance the growth of some organism and to repress that of others.
2. Classification of organic material by using solid absorbents that have affinities for specific elements.
3. An analytical technique in which organic compounds are separated by chromatography and identified by studying their effects on microorganisms.
1. A microorganism that can derive the energy required for growth from oxidation of inorganic compounds such as hydrogen sulfide or ammonia.
2. Any autotrophic bacteria or protozoan that is not involved in the process of photosynthesis.
3. An organism that depends on chemicals for its energy and principally on carbon dioxide for its carbon.
chemoautotrophic (adjective)
A reference to an organism that produces its own food using inorganic materials and chemosynthesis; such as, certain bacteria.
A reference to microorganisms that obtain metabolic energy by the oxidation of inorganic substrates, such as sulphur, nitrogen, or iron; chemotrophic.
